Can we live in Kepler-452b?
We don’t know whether life exists on Kepler-452b, but we do know that it has some things in common with the Earth. Astronomers say that the planet is in the “Goldilocks zone”, meaning that the distance of the planet from its star is just right, making it not too hot and not too cold for life to exist.
Is there two Earth in the solar system?
Two earths, one solar system. In 2015, NASA’s super powerful Kepler Space Telescope discovered the closest copy of Earth to date. It’s called Kepler-452. Often nicknamed “Earth 2.0,” Kepler-452 orbits a star about the same size as our Sun every 385 days.

Which planet can support life?
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
What if there was a second Earth?
Since the Earth travels at almost 19 miles per second, or 67,000 miles per hour, two Earths smashing into each other would wipe out all life on each of them instantaneously. If “Earth 2” were simply another inner planet within our solar system’s habitable zone, then the planetary pile-up could well be avoided.
