Kepler-1031 and Its Sub-Earth Planet
Kepler-1031 is a star 2230 light-years away with one planet, Kepler-1031 b. The star is 3.39 billion years old and has a mass of 1.09 solar masses, a radius of 1.12 solar radii, and a temperature of 6010 K. Its reported mass estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.
Kepler-1031 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. The planet is classified as a Sub-Earth, a size class for planets smaller than Earth. Its radius is 0.87 Earth radii, and its orbital period is 1.23 days.
