How Long Could You Survive on Each Planet?

Today I break down one of the most extreme questions in space science and human survival: how long could you actually survive on each planet in our solar system with no spacesuit?From the crushing pressure of Venus, to the near-vacuum of Mars, to the chaos of the outer planets, every world presents a completely different way your body would fail. Some environments are instantly lethal, others give you just enough time to realize what’s happening, and that’s where things get interesting.This episode explores planetary environments, atmospheric pressure, temperature extremes, and the limits of human physiology in space. If you’ve ever wondered what would happen if you were suddenly exposed to another planet’s surface, this is the breakdown.And yes…I have a ranking system.Music thanks to Zapsplat.#SpaceFacts #Astronomy #ScienceExplained #planets #hypothetical #solarsystemHowStuffWorks.
