Venus is the hottest planet in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.
What is the next livable planet?
Another likely candidate is Alpha Centauri, Earth’s nearest Sun-like star system 4.37 light-years away. Estimates place the probability of finding a habitable planet around Alpha Centauri A or B at roughly 75%.
Can we live on Titan?
Plus, Titan is the only place in the solar system, other than Earth, with stable surface liquids: Titan has lakes and seas on its surface. … But these damaging particles cannot make it to Titan’s surface; they’re absorbed by the atmosphere, meaning that it’s a safe environment for humans.

What would happen if the moon broke apart?
If the moon exploded, the night sky would change. We would see more stars in the sky, but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter, and our ocean tides would be much weaker.
