Can a exoplanet support life?
A potentially habitable exoplanet is a hypothetical type of planet that has liquid water and may support life. As of March 2020, a total of 55 potentially habitable exoplanets have been found.

Which planet has a life?
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
Is Earth the only planet with life?
Among the stunning variety of worlds in our solar system, only Earth is known to host life. But other moons and planets show signs of potential habitability.
Which planet is the best to live on?
Mars is the best planet because Mars and Earth have more in common than any other worlds in the solar system. It cowers next to humongous Jupiter, but unlike that gas giant, its hard surface beckons visitors.
What is the second most livable planet?
Kepler-452b

What makes an exoplanet habitable?
The standard definition for a habitable planet is one that can sustain life for a significant period of time. As far as researchers know, this requires a planet to have liquid water. To detect this water from space, it must be on the planet's surface.
Is Kepler 452b habitable?
Kepler-452b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. … The habitable zone is a region around a star where temperatures are right for water—an essential ingredient for life as we know it—to pool on the surface.
