Kepler-1222 and Its Sub-Earth Planet
Kepler-1222 is a star located 1350 light-years away, and it hosts one known planet. The star is 4.37 billion years old, has a mass of 0.84 solar masses and a radius of 0.8 solar radii, and its temperature is 5240 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet Kepler-1222 b was discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1222 b has an orbital period of 1.92 days and a radius of 0.79 Earth radii, smaller than Earth's. As a Sub-Earth, it is smaller in radius than Earth.
