What is the closest possible habitable planet?
What is life like on Proxima b? This planet in the next star system along is, at just four light-years, by far the closest Earth-like planet we know about.
Is Earth the only planet that can support life?
Life on Earth Earth is the only planet in the universe known to possess life.

What makes a planet more habitable than Earth?
Some of these systems also contain stars — potentially — even friendlier to life than our Sun. These superhabitable systems are generally warmer, wetter, larger and older than Earth, potentially making these worlds more habitable than Earth.
Can a planet be habitable but uninhabited?
“A planet can be habitable or superhabitable but uninhabited. This has to do with the natural history of the planet. There could have been a calamity (like a nearby Supernova explosion).” Schulze-Makuch identifies a superhabitable planet as “any planet that has more biomass and biodiversity than our current Earth.”
Is it better to live on bigger or smaller planets?
Also, when it comes to planets, bigger is better. A planet that’s even 10\% larger than Earth means it has more habitable land.
What makes a planet superhabitable?
These superhabitable systems are generally warmer, wetter, larger and older than Earth, potentially making these worlds more habitable than Earth. Stars with lifespans longer than the Sun would allow solar systems more time to develop life, researchers speculate.
