A spacesuit designed for Venus would need to be constructed of titanium. Its surface. How could this be possible? No such luck on Venus or Mars, though, with the surface of the former being hot enough to melt lead, and the second dropping lower than -150oC (-225oF). Its surface pressure is also about 90 times greater than that of Earth. Why Is Microsoft Planning To Move Data Centers Under Water?

The Armstrong limit, often called Armstrong’s line, is the minimum altitude beyond which the boiling point of water becomes so low, that it is  almost equal to the normal temperature of the human body. (That’s how long it would take the … We would get vaporized in less than a second, even with a spacesuit on, let alone without one! The time period of survival is roughly a second, even though the gravity force is equal to that of Earth (the more you know!). The temperature on its surface is approximately 400C. To put things into perspective, Earth receives enough. It’s just a big ball of nothing (until you reach the core). The surface pressure is well below the Armstrong limit for the unprotected human body.

Visiting Venus would be like landing inside of an oven. What Would Happen If The Sun Suddenly Disappeared? Just like Jupiter, Saturn, Uranus  and Neptune are enormous balls of gas. remember, Earth is the only planet that has life-giving chocolate! As everyone knows, the lack of oxygen, extreme temperatures and atmospheric pressures of our planetary neighbors don’t make for ideal conditions if you’re an earthling. The spacesuit completely covers a spacewalker's body. At its hottest, Mars could hit 80°F near the equator in the middle of the day. We would need to blast off from Mars. All this begs the question, which planet would you last the longest on without a space suit? However, for the sake of argument, what if someone decided to jump into space without a space suit?

Jupiter is literally just a ball of gas, so there’s nothing to land on. Obviously, visiting other planets comes with all sorts of other complications. To put things into perspective, Earth receives enough solar energy in an hour to satisfy the entire world’s energy requirements. You've found yourself "spaced": tossed out of the airlock of a capsule or space station without a spacesuit.
