0:01 Let's start with the ones that are
0:03 terrifying and work our way towards the
0:05 ones that are hellish nightmares. Number
0:08 seven, the burning ice planet. Giza 436b
0:10 is one of the most terrifying planets
0:13 you will ever hear about. A hot Neptune
0:15 gas giant that orbits very close to its
0:17 star and is about four times Earth's
0:19 radius. But let's talk about what makes
0:21 this planet so terrifying. It is
0:23 believed that the planet's entire
0:26 surface is covered in extremely hot ice
0:28 capable of reaching temperatures above
0:30 800° F. Now, I know that sounds
0:33 confusing and makes no sense. But don't
0:36 worry, lucky for you guys, I know how to
0:38 read, so let me break this down a bit
0:40 further. This bizarre superheated ice is
0:42 formed by the planet's immense
0:45 atmospheric pressure, not by cold. But
0:46 instead of me just rambling off facts
0:48 and telling you about these terrifying
0:50 planets, let's make this a bit more fun.
0:52 I will be placing you on each of these
0:54 planets so we can see exactly what would
0:56 happen to a human under these extreme
0:59 conditions. Let's begin. You are now in
1:01 a modern spaceship and are just about to
1:05 enter Giza 436b's atmosphere. A terrible
1:07 decision. Instantly, the spaceship
1:09 begins to overheat and its structural
1:12 components start to deform thanks to the
1:14 planet's atmosphere being primarily made
1:16 of heated helium and hydrogen. Around
1:18 the 30-second mark, things can go one of
1:20 two ways. The ship could be crushed from
1:22 the increasing pressure or the entire
1:24 ship could vaporize from the blazing
1:27 heat. Congratulations, you survived
1:29 anywhere from 30 to 90 seconds. But for
1:31 the sake of the video, let's say you
1:33 were in an indestructible spacecraft and
1:35 managed to safely land on the planet's
1:38 icy surface. What would you experience
1:40 then? As you step out of the ship, all
1:42 the moisture in your body instantly
1:46 flash boils, then vaporizes, leaving you
1:48 dead within a couple of seconds. Let's
1:50 try that again, but this time you're
1:52 wearing an indestructible spacuit. As
1:54 you step out of the ship, you see the
1:57 glowing ice covered surface and you feel
2:00 the spacuit vibrate from the high winds.
2:02 You look up and are greeted with a dark
2:05 black red sky. Powerful lightning storms
2:07 light up the atmosphere, revealing the
2:09 enormous and violent storms all around
2:12 you. Honestly, it's a pretty chill
2:14 experience compared to what's to come.
2:17 Number six, the terrifying gas planet HD80606b
2:19 HD80606b
2:22 is yet another horrifying planet. A hot
2:24 Jupiter gas giant with a wildly
2:26 elongated orbit that is about 11 times
2:29 larger than Earth's radius. The reason
2:31 why this planet is so scary has to do
2:33 with its incredibly wild temperature
2:36 swings as it goes from deep space to
2:38 nearly touching its star. When the
2:40 planet is closest to its star, the
2:42 temperature goes from around 450 to over
2:47 2,000° F in just 6 hours. Now, I know
2:49 it's hard to visualize these numbers, so
2:51 let me put it in a way we can all
2:53 understand. 450°
2:57 cooks a beautiful pizza, while 2,000°
3:00 cooks a terrible pizza. Hope that helps.
3:02 But let the simulation begin. You are
3:04 back in a modern-day spaceship and are
3:06 about to enter the planet's atmosphere.
3:08 Of course, you will be entering the
3:10 planet at its hottest. As you enter, the
3:12 ship's speed instantly begins to
3:14 accelerate at incredible speeds thanks
3:17 to the planet's gravitational pool.
3:18 Within seconds, the outside of the
3:21 ship's temperature rises over 7,000°,
3:23 which begins to erode the craft's heat
3:26 shield. Around the 30-second mark, you
3:28 begin to descend past violent storms,
3:31 high winds, and violent jet streams as
3:34 pieces of your ship melt and vaporize.
3:36 Around 60 seconds, the hull begins to
3:38 deform and eventually implode due to the
3:41 everinccreasing atmospheric pressure,
3:44 which means you have imploded as well.
3:46 Congratulations. You survived an entire
3:49 minute, a new personal best. Let's try
3:51 that again. But this time, you invested
3:53 in Bitcoin at 10 cents and were able to
3:55 purchase an indestructible spacecraft.
3:57 So, what would happen if you were to
3:58 step out of the ship at the planet's
4:00 buoyancy point wearing no protective
4:03 gear? In less than a millisecond after
4:05 the hatch opens, you would be crushed to
4:07 a pulp, then completely vaporized into
4:09 the metallic ocean. Now, for that one
4:12 person at NASA who accidentally let this
4:14 video autoplay, I got you. If you were
4:16 to step outside the ship, this time
4:19 wearing a modern-day NASA space suit,
4:20 you would be crushed to a pulp than
4:23 completely vaporized. This is because
4:24 the atmosphere is millions to hundreds
4:26 of millions of times more pressurized
4:29 than Earth's, and oceans made of metal
4:31 are apparently very hot. Let's try that
4:32 again, but this time you're wearing an
4:35 indestructible and highly advanced space
4:37 suit. What would you experience then? As
4:40 you exit the spaceship, you instantly
4:42 lose sight of it in the hazy glowing
4:45 infinite ocean. You no longer know up
4:48 from down as you float suspended in the
4:50 endless abyss. Out of nowhere,
4:53 electrical currents trickle around you,
4:56 giving off light, if only for a second.
5:00 An absolute nightmare. permanently stuck
5:03 playing an ocean level. Number five, the
5:05 disappearing planet. Cororo 7b is one of
5:07 the hottest rocky planets ever
5:09 discovered. A rocky super Earth,
5:12 approximately 70% larger in radius than
5:14 Earth. Now, what makes this planet so
5:17 terrifying is its extreme proximity to
5:20 its star as it is 60 times closer to its
5:22 sun than Earth is. It is also tidily
5:24 locked, meaning that the same side is
5:26 always facing its star, creating a lava
5:29 ocean on one side and a dark rocky oven
5:32 inferno on the other. The planet reaches
5:34 temperatures up to 3,600°
5:37 F, which is so hot that its rocky
5:39 surface is literally evaporating into
5:42 space, slowly shrinking the planet.
5:43 Here's what would happen if you were to
5:45 enter the planet's atmosphere with this
5:47 state-of-the-art spacecraft. Instantly,
5:49 the craft's heat shield reaches over
5:52 7,000° and begins to erode rapidly.
5:54 [music] Within 20 seconds, the craft's
5:56 outer shell begins to crack and melt,
5:58 destroying insulation and causing the
6:00 inside of the ship's temperature to
6:03 quickly rise, baking you alive. Within
6:06 30 to 45 seconds, the entire ship is
6:08 shredded to pieces, then quickly
6:10 vaporize with no traces of its existence
6:12 left behind. But let's say you were in
6:14 an indestructible ship and managed to
6:17 land on the planet's surface. What would
6:19 happen then? As the hatch opens, your
6:22 eyes, skin, and organs would vaporize in
6:25 seconds before you ever felt a thing.
6:27 Let's try that again, but this time
6:28 you're in an indestructible and highly
6:31 advanced space suit. As you step out of
6:32 the ship, you're instantly blinded by
6:35 the sun. Since it's 360 times larger
6:38 than our sun from Earth, luckily, you
6:40 would be able to walk on the lava ocean
6:42 since molten rock is incredibly dense.
6:44 It would feel like walking on burning
6:46 tar that clings to your feet with every
6:48 step you take, turning the fun outdoor
6:51 adventure into an exhausting workout.
6:53 But if you were lucky enough to spawn on
6:54 the dark side of the planet, you would
6:56 actually be able to walk around freely
6:59 on solid ground. Well, at least when
7:00 you're not busy being tossed hundreds of
7:02 feet into the air by the planet's
7:04 violent and powerful winds. Number four,
7:09 Wasp 127b. Wasp 127b is yet another
7:11 incredibly horrifying planet. a gas
7:14 giant that is about 15 times Earth's
7:16 radius. One of the many reasons why this
7:18 planet is so terrifying is that it
7:20 currently holds the record for the
7:22 highest winds ever recorded. For
7:24 reference, the highest non-turnatic wind
7:26 speed ever recorded on Earth is
7:30 approximately 250 mph, which is strong
7:31 enough to send a human hundreds of feet
7:34 into the air. Neptune, which has the
7:36 highest winds in our solar system, has
7:39 winds that reach as high as 1,500 mph,
7:41 faster than the speed of sound and
7:43 almost four times faster than the winds
7:46 of Jupiter's red spot. Winds this high
7:48 would obliterate you on contact,
7:50 reducing your body to a cloud of
7:53 vaporized tissue. But get this, WASP
7:56 127b has a recorded wind speed of over 20,500
7:58 20,500
8:01 mph. A regular person hit by a wind
8:03 force this strong would be completely
8:06 erased from existence instantaneously.
8:08 But okay, let's say you manage to enter
8:10 the planet's atmosphere with a modern
8:12 spacecraft. [music] Within 5 to 10
8:14 seconds, the craft's heat shield is
8:16 destroyed by the thick metalrich
8:19 atmosphere. Around the 15-second mark,
8:21 the craft and everything inside is torn
8:23 apart and swept into the jetream. The
8:25 craft and your body are shredded,
8:28 scattered, and absorbed into the winds,
8:30 erased. so completely that it's as if
8:33 you were never there. But just for fun,
8:35 let's say you were a stormchaser with
8:37 tech so advanced you could fly into
8:38 these storms in an indestructible
8:40 spacecraft and stepped out in an
8:43 indestructible space suit. Well, you
8:45 would instantly be taken by the wind and
8:47 crushed inside of the suit from the
8:50 extreme G-forces, separating soft tissue
8:52 from the bones. Obviously, the suit
8:54 still needs a bit of work. Number three,
8:58 the iron rain furnace. WASP 76b is a
9:00 terrifying hot Jupiter gas giant
9:02 infamous for its molten iron rain and
9:05 winds that reach over 10,000 mph. The
9:07 planet is massive, nearly twice the size
9:09 of Jupiter's radius and around 20 times
9:12 Earth's. The planet is also so close to
9:14 its star that it's tidily locked. One
9:16 side is forever scorched by intense
9:18 heat, while the other remains a dark,
9:21 hellish landscape lit only by its molten
9:23 iron rain. But let's say you were placed
9:25 in charge of a modern spacecraft and
9:27 enter the planet's atmosphere on its
9:30 sunny side. The craft will immediately
9:31 report temperatures hotter than molten
9:34 lava. Around the 3-second mark, the heat
9:35 begins to destroy the craft's heat
9:37 shield thanks to the iron vapor in the
9:39 atmosphere. And around the 5 to 10
9:41 second mark, the craft's entire
9:44 structure begins to melt, which includes
9:46 you. Around the 20 second mark, the
9:48 entire craft and you are nothing but
9:51 debris taken by the high winds, which
9:52 eventually get so hot that they
9:55 vaporize, leaving no traces of your
9:57 existence. Since I've already covered
9:59 what would happen if you exited a ship
10:01 at the buoyancy point of a gas planet,
10:02 let's switch it up a bit. This time,
10:04 you're an adrenaline junkie looking for
10:06 your next fix. So, you'll be skydiving
10:09 into the planet and gulping down some
10:11 air. Within a fraction of a second,
10:14 you're incinerated. Now, just because I
10:15 know you're wondering, let's say you
10:17 skydived on the dark side of the planet,
10:20 away from its sun. Within a fraction of
10:23 a second, your skin and eyes flash. Your
10:25 lungs and organs collapse under the
10:27 atmospheric pressure. And as your body
10:30 is ragdalled across the sky, molten iron
10:33 rain sears through your crushed body.
10:35 Within one to two seconds, the scorching
10:37 winds shred you into tiny pieces, which
10:40 quickly sizzle into vapor carried away
10:42 by the storm. So, a bit better this
10:45 time. But let's say you exited the craft
10:47 wearing an indestructible spaceacuit and
10:49 decided to skydive into the planet. What
10:52 would you experience then? As you freef
10:54 fall through thin gas clouds, your
10:56 descent quickly increases in speed. A
10:59 few minutes later, the sky shifts into a
11:01 glowing orange haze. As you continue
11:02 passing through thick vapors in the
11:05 atmosphere, out of nowhere, your body is
11:07 violently spun and tossed in random
11:10 directions as supersonic winds slam into
11:12 you. That's when the noise of the storm
11:14 roars all around you as if you were
11:17 inside a massive hurricane. Lightning
11:19 storms arc overhead, exposing the alien
11:21 metallic clouds in the environment.
11:23 Around this point, you will see the
11:26 infamous molten iron rain spreading as
11:28 far as your eyes can see. As you
11:30 continue to fall deeper into the
11:32 atmosphere, light fades, sounds
11:35 disappear as you are submerged deeper
11:37 into the reflective ocean of metallic
11:40 hydrogen. Once you finally reach the
11:42 planet's core, you will be completely
11:44 surrounded by what looks like a glowing
11:46 fog made of superheated matter. Your
11:50 final resting place. Number two, the
11:53 planet being eaten alive. Wasp 12b is
11:55 one of the most unique and terrifying
11:57 planets ever discovered. This is what
12:00 the planet looks like. Disgusting. The
12:02 reason it looks so ugly and deformed is
12:04 that it's currently in a death spiral
12:07 with its star slowly being eaten alive.
12:09 A visible trail of gas can be seen
12:11 feeding the nearby star. Its close
12:13 proximity to its star also means it's
12:16 tidily locked. So, one side is forever
12:18 scorched with radiation and heat, while
12:20 the other is forever scorched with
12:23 radiation and heat, but also completely
12:25 dark. The planet is a hot Jupiter gas
12:27 giant that is almost twice the radius of
12:30 Jupiter and nearly 22 times Earth's. But
12:32 let's get to the good stuff. Let's say
12:33 you were to enter the planet's
12:36 atmosphere on the ugly deformed side.
12:38 Well, surprisingly, you would still be
12:39 pulled towards the planet rather than
12:41 the star since at this range, the
12:43 planet's gravitational pull is much
12:45 stronger. The moment you enter, the
12:47 craft's [music] heat shield begins to
12:49 glow from the intense heat, and the
12:51 temperature inside quickly begins to
12:54 skyrocket as well. Around the 5 to 20
12:57 second mark, winds as high as 1,000 mph
13:00 slam into the craft, vaporizing the
13:02 craft's shielding at incredible speed.
13:05 Then around the 20 to 60 second mark,
13:08 the entire ship is fully consumed,
13:10 shredded apart into molten debris as the
13:12 metal becomes liquid before everything
13:15 eventually vaporizes. Let's try again,
13:16 but this time you've entered the cheat
13:19 code indestructible spacecraft. And
13:20 [music] instead of exiting at the
13:22 planet's atmosphere, buoyancy point, or
13:25 core, you will be exiting here, right at
13:28 the center of the planet and its star.
13:29 Time to find out whether you would go
13:32 towards the star or towards the planet.
13:39 Place your bets in three, two, one, go.
13:40 Okay, try again, but this time we're
13:42 shedding the bulk and heavy weight of
13:44 the ship, only wearing a light and
13:47 indestructible spaceuit. Where would you
13:52 go then? Place your bets and three, two,
13:56 one, go. Yeah, obviously you head
13:58 towards the star again. That should have
14:01 been really, really obvious. Number one,
14:05 the glass storm planet. HD189733b
14:08 is a hellish planet that is worse than
14:10 any nightmare you could ever possibly
14:12 dream of. The planet is enormous, around
14:15 15 times Earth's radius. From the
14:17 outside looking in, it appears to be a
14:19 larger version of Earth covered with
14:21 beautiful tropical beaches. But I guess
14:23 it's time to find out what would happen
14:24 if you were to enter this planet's
14:27 atmosphere. You are back in a modern-day
14:29 spacecraft and have just entered what
14:31 you thought was a vacation getaway.
14:32 [music] Instantly, the ship begins to
14:34 glow due to the high heat of the
14:36 atmosphere. A great sign that you picked
14:38 the right day to go to the beach. Around
14:40 the 5-second mark, the craft's heat
14:43 shield begins to warp, melt, and
14:45 vaporize. 10 seconds in, supersonic
14:48 winds slam into the craft as molten
14:50 glass particles in the atmosphere shred
14:52 the craft to [music] tiny pieces. Within
14:55 20 to 30 seconds, the tiny pieces of the
14:58 craft and you are completely vaporized
15:00 and carried away by the wind. It turns
15:02 out that the planet is in a giant ocean
15:04 of water. It's almost entirely made up
15:06 of scorching hot hydrogen and helium,
15:09 reaches a whopping 2,200°
15:12 F, has stronger winds than Neptune, and
15:15 even rains molten glass sideways, making
15:18 it a horrible planet to vacation to. So,
15:20 you're probably wondering, why the hell
15:22 is the planet blue if it wasn't meant to
15:24 have any visitors? Well, that's because
15:26 the planet's atmosphere contains tiny
15:28 particles of glass, which are great at
15:30 scattering blue light, making it the
15:33 worst scam in the known universe. And
15:34 another reason why it deserves the
15:37 number one spot. And yes, just like all
15:39 gas planets, the simulation always ends
15:41 the same. Instant vaporization anywhere
15:43 on the planet, followed by suspended in
15:46 the dark metallic oceans. Honestly, we
15:48 are sick of these planets and we hate them.
15:49 them. [music]
