Kepler-303 is a star with 0.3799999999999998 times the mass of the Sun, and 0.48 times its radius. It is located 688.22 light years away from the solar system.
Kepler-303 is known to have 2 exoplanets in orbit around it.
Kepler-303 b was discovered by the Kepler observatory using the transit method. Its discovery was announced in 2014-03. Its semi-major axis is 0.02 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 1.94 Earth days to complete an orbit around its host star, Kepler-303.
The mass of Kepler-303 b is 0.72 times the mass of Earth. The radius of Kepler-303 b is 0.89 that of Earth. At less than 1.5 Earth masses, Kepler-303 b is a regular terrestrial planet, much like the terrestrial planets we find in our solar system, namely Mercury, Venus, Earth and Mars.
