Kepler-1649 and Its Two Earth-Like Planets
Kepler-1649 is a single star located 301 light-years away, with two planets orbiting it. The star has a reported mass estimate of 0.198 solar masses, a reported radius estimate of 0.232 solar radii, and a temperature of 3240 K. Its mass, radius, and temperature are all lower than the Sun's corresponding values.
Both planets are Earth-like and were found by transit, the dimming of a star's brightness when a planet crosses in front of it. Kepler-1649 b was discovered in 2017 and has an orbital period of 8.69 days and a radius of 1.02 Earth radii. Kepler-1649 c was discovered in 2020 and has an orbital period of 19.5 days and a radius of 1.06 Earth radii.
Among the listed planets, Kepler-1649 b has the shortest year and the smallest radius by reported estimates, while Kepler-1649 c has the longest year and the largest radius by reported estimates.
