Kepler-452b, sometimes called “Earth 2.0” or “Twin Earth,” is the planet with the most similar environment to our own. Kepler-452b was discovered by NASA’s Kepler satellite in 2015. This planet is located in the Kepler-452 star system, a star system similar to the Sun but larger and older.
Similarities of Kepler-452b to Earth:
Size and mass: Kepler-452b is larger in size and mass than Earth and is considered a “super-Earth” when there is the possibility of liquid water on the surface.
Orbit: Kepler-452b orbits its star at a similar distance as Earth orbits the Sun. Therefore, it receives the same amount of light and heat from the star as Earth.
Rotation time: The time it takes Kepler-452b to orbit its star is 385 days, which is almost the same as the 365 days it takes the Earth to orbit the Sun.
Kepler-452b has an environment suitable for life. So the question is whether there is any life on this planet. This is an issue that is being researched.
However, there is some possibility that Kepler-452b may differ from Earth in some other ways, and we need more research to better understand it.
