1. 0:00Mercury Mercury is the closest planet to
2. 0:02the Sun but if you think that means it's
3. 0:04hot all the time you're wrong at night
4. 0:06temperatures can plummet to an icy minus
5. 0:09180° C during the day however they can
6. 0:12Skyrocket to 430° C this extreme
7. 0:15imbalance happens because Mercury
8. 0:17doesn't have a proper atmosphere to
9. 0:19regulate temperature instead it has a
10. 0:21very thin exosphere which doesn't
11. 0:22maintain heat while apart from
12. 0:24temperature you wouldn't have to worry
13. 0:25about weather on Mercury the real
14. 0:27dangers come from solar radiation and
15. 0:29the lack of breathable air in fact
16. 0:31Mercury gets almost seven times the
17. 0:33solar irradiance that Earth receives as
18. 0:35the smallest planet in the solar system
19. 0:37Mercury is full of craters Cliffs and
20. 0:39bumpy terrain making it a pretty tough
21. 0:41place to land as well the low air
22. 0:43resistance doesn't help either it would
23. 0:44make slowing down a spaceship much
24. 0:46harder increasing the chances of a
25. 0:48high-speed crash landing during the
26. 0:50daytime is out of the question because
27. 0:51of the extreme heat the latest NASA SPAC
28. 0:54suits can only handle up to 121° C
29. 0:57nowhere near Mercury's daytime
30. 0:59temperatures of 430° C plus keep in mind
31. 1:03that Mercury's day lasts about half a
32. 1:04year due to its slow rotation nighttime
33. 1:07isn't much better temperatures of - 180°
34. 1:10C far exceed NASA suit's lower limit of
35. 1:13- 157° c so you'd still freeze your best
36. 1:17bet would be to try Landing in The
37. 1:18Terminator Zone the area between day and
38. 1:20night where temperatures are more
39. 1:22moderate even there however it can be
40. 1:24risky as temperatures can change
41. 1:25relatively quickly Venus Venus is the
42. 1:28closest planet to Earth Earth sitting
43. 1:30just 40 million km away this means the
44. 1:32journey there would be relatively short
45. 1:34about 4 months its size and gravity
46. 1:36wouldn't pose much of a problem as
47. 1:38they're pretty similar to Earth's the
48. 1:39first real issue you'd face though would
49. 1:41be those beautiful yellow clouds you'd
50. 1:43see as you approached the surface
51. 1:45unfortunately they're made of sulfuric
52. 1:47acid a highly corrosive substance that
53. 1:49would destroy your lungs in seconds but
54. 1:51let's assume you've got a space suit
55. 1:52Advanced enough to filter it out as you
56. 1:54descend to the surface you'd notice
57. 1:55visibility dropping drastically the
58. 1:57atmosphere becomes incredibly thick made
59. 1:59most of carbon dioxide so you wouldn't
60. 2:01be able to see much then there's the
61. 2:03heat an unbearable 450° C if that wasn't
62. 2:06enough only about 10% of the sunlight
63. 2:08reaches the surface as it's blocked by
64. 2:10the thick atmosphere so it would be
65. 2:12pretty dark on the surface moving your
66. 2:14arms and legs would be a serious
67. 2:15struggle even though gravity is nearly
68. 2:17the same as on Earth the air is so dense
69. 2:19you'd feel like you're waiting through a
70. 2:21heavy liquid with a good pressurized
71. 2:23suit you might last a few seconds down
72. 2:25there but before long the pressure about
73. 2:2792 bars compared to Earth's one bar at
74. 2:30level would crush your suit and if that
75. 2:31didn't kill you the sulfuric acid you'd
76. 2:34start breathing once your suit broke
77. 2:35definitely would Mars Mars is the second
78. 2:38closest planet to Earth and the most
79. 2:40habitable of all eight planets daytime
80. 2:42temperatures are much less extreme
81. 2:44compared to Mercury and Venus reaching
82. 2:46up to a relatively comfortable 20° C
83. 2:49however the real challenge comes at
84. 2:50night or in certain parts of the planet
85. 2:52where temperatures can drop as low as
86. 2:55-13° another big issue similar to
87. 2:57Mercury is Mars's incredibly thin thin
88. 3:00atmosphere it's mostly made up of carbon
89. 3:01dioxide with only Trace Amounts of
90. 3:03oxygen meaning there's not that much
91. 3:05breathable air this thin atmosphere also
92. 3:07results in low pressure and high levels
93. 3:09of radiation exposure both of which are
94. 3:11incredibly dangerous the average natural
95. 3:14radiation level on Mars is 24 to 30 RADS
96. 3:17which is about 40 to 50 times the
97. 3:19average on Earth on top of that Mars
98. 3:21experiences frequent and extremely
99. 3:22violent dust storms with wind speeds
100. 3:24reaching up to 100 kmph these storms
101. 3:27could pose serious challenges so any
102. 3:29attempt at habitation would require a
103. 3:31sustainable airtight and well insulated
104. 3:33life support system Jupiter Jupiter is
105. 3:36the biggest planet out of the eight and
106. 3:38it's one of the hardest planets to land
107. 3:39on primarily because of its extreme
108. 3:41radiation levels even 300,000 km away
109. 3:44the radiation would start penetrating
110. 3:46your suit and you'd be done for but
111. 3:48since that's a boring outcome let's
112. 3:49assume you have a hypothetical suit that
113. 3:51can block the radiation Jupiter's
114. 3:53gravity is 2.4 times stronger than
115. 3:55Earth's meaning you'd be falling
116. 3:57incredibly fast as you enter the first
117. 3:59layers of the atmosphere you'd encounter
118. 4:01white clouds made of Frozen ammonia
119. 4:03crystals with temperatures around
120. 4:05-150° C the winds here are no joke
121. 4:08reaching insane speeds of up to 482 kmph
122. 4:12if you manage to descend about 150 km
123. 4:14through these top layers you'd reach the
124. 4:16deepest point ever explored this is how
125. 4:18far NASA's Galileo probe got back in
126. 4:211995 Beyond this point things start
127. 4:23getting darker and both temperature and
128. 4:25pressure increase rapidly just as a fun
129. 4:27fact the pressure near Jupiter's center
130. 4:29is estimated to be about 100 million
131. 4:31times Earth's atmospheric pressure after
132. 4:33hours of falling you might reach
133. 4:35Jupiter's inner layers where you'd
134. 4:36encounter a super critical fluid a state
135. 4:38that's not quite liquid but not gas
136. 4:40either here you'd kind of be swimming in
137. 4:42this bizarre substance if you continued
138. 4:44further toward the center you'd
139. 4:46encounter metallic hydrogen an extremely
140. 4:48dense liquid that would trap you but if
141. 4:49you somehow managed to get through that
142. 4:51you'd reach Jupiter's core though we're
143. 4:53not entirely sure if it's solid or not
144. 4:55the temperatures here would be about
145. 4:5624,000 de C roughly 4 . 5 times hotter
146. 5:00than the sun's surface Saturn Saturn is
147. 5:04the second largest planet in the solar
148. 5:05system with an atmosphere primarily made
149. 5:07of hydrogen and helium the first
150. 5:09challenge would be avoiding a crash with
151. 5:11one of its 146 orbiting moons once you
152. 5:14manage that you'd encounter its iconic
153. 5:16Rings which are made of debris from old
154. 5:18moons ice pellets comets and asteroids
155. 5:20let's assume you're either an incredibly
156. 5:22skilled pilot or your spaceship is
157. 5:24indestructible so you don't meet your
158. 5:25end by smashing into space junk as you
159. 5:28approach Saturn's equator you'd w winess
160. 5:29an incredible spectacle of red and
161. 5:31purple auras caused by highly energetic
162. 5:34hydrogen in the atmosphere however this
163. 5:36beauty comes with a catch hurricane
164. 5:37force winds blasting at speeds of around
165. 5:401,800 kmph would make it nearly
166. 5:43impossible to stay steady trying to
167. 5:44enter from the North Pole wouldn't be
168. 5:46any better up there you'd face a massive
169. 5:48storm so large you could fit Two Earths
170. 5:51inside it this region also has ammonia
171. 5:53clouds similar to Jupiter's and
172. 5:55temperatures that can plummet to a bone
173. 5:56chilling minus 250° c as as you fall
174. 6:00deeper through the layers of clouds the
175. 6:01temperatures would start to rise again
176. 6:03eventually reaching 0° C at this point
177. 6:06while the cold becomes less of an issue
178. 6:08pressure becomes your biggest enemy it
179. 6:10increases to levels comparable to the
180. 6:11deepest parts of Earth's oceans
181. 6:13continuing further the gases around you
182. 6:15would transition into a liquid state if
183. 6:17you somehow survived long enough to
184. 6:19reach the center of Saturn you'd
185. 6:20encounter its molten Rocky core which is
186. 6:22about 10 times the size of Earth
187. 6:24temperatures here reach a scorching
188. 6:2611,700 de C more than twice as hot as
189. 6:30the sun's surface with pressure roughly
190. 6:321,000 times greater than Earth's Uranus
191. 6:35this is where planets start getting
192. 6:37really far from Earth making the journey
193. 6:38incredibly long Uranus is one of the two
194. 6:41ice Giants and the only planet in the
195. 6:42solar system that spins on its side it
196. 6:44also rotates faster than Earth with a
197. 6:47day lasting just 17 Earth hours by the
198. 6:49way being an ice giant doesn't mean the
199. 6:51planet is a solid ball of ice instead it
200. 6:53means it's primarily composed of
201. 6:55elements heavier than hydrogen and
202. 6:56helium like Saturn you'd need to avoid
203. 6:58crashing into rings once you pass them
204. 7:01you'd find yourself surrounded by toxic
205. 7:03gas and the temperature would drop
206. 7:04rapidly to below -2 200° C this makes it
207. 7:08the coldest planet in the solar system
208. 7:10if the freezing cold and poisonous
209. 7:11atmosphere didn't get you you'd descend
210. 7:13through the first layer of the
211. 7:14atmosphere here things get even worse
212. 7:17the air becomes dense and you'd be
213. 7:18pelted by ice pellets eventually you'd
214. 7:20reach something truly spectacular a rain
215. 7:22of diamonds driven by Winds of up to 900
216. 7:25kmph but once again there's a catch the
217. 7:28pressure here is about 100 times greater
218. 7:30than Earth's which would ultimately
219. 7:31Crush you Neptune Neptune is the second
220. 7:34ice giant after Uranus and its
221. 7:36composition is very similar being the
222. 7:38farthest planet from the sun 30 times
223. 7:40farther than Earth it's incredibly dark
224. 7:43like Uranus Neptune is extremely cold in
225. 7:45its outer layers but the inner layers
226. 7:47are intensely hot due to immense
227. 7:49pressure and heat from its core matter
228. 7:51of fact its core is about 7,000 de cels
229. 7:54which is hotter than the sun's surface
230. 7:56it also experiences the famous Diamond
231. 7:57rain caused by high pressure breaking
232. 7:59down methane and forming solid diamonds
233. 8:02Neptune's winds are among the strongest
234. 8:04in the solar system reaching supersonic
235. 8:06speeds in many ways it's basically a
236. 8:08twin of Uranus so there isn't much to
