The Kepler-452 Exoplanetary System
Kepler-452 is a star with 1.04 times the mass of the Sun, and 1.11 times its radius. It is located 1828.50 light years away from the solar system and is estimated to be 6 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
Kepler-452 is known to have 1 exoplanets in orbit around it.
Kepler-452 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2015-07. Its semi-major axis is 1.05 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 384.84 Earth days to complete an orbit around its host star, Kepler-452.
The mass of Kepler-452 b is 3.09 times the mass of Earth. The radius of Kepler-452 b is 1.63 that of Earth. At 3.09 Earth masses, Kepler-452 b is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. No Super Earths are known to exist in our solar system, but if it exists, the so-called Planet Nine could very well be a super Earth, as it is hypothesized to have a mass between five and ten Earth masses.
With a semi-major axis of 1.046 astronomical units, and a mass of 3.09 Earth masses, Kepler-452 b could, potentially, be a habitable planet with stable bodies of liquid water on its surface, like Earth.
