Kepler-887: A Distant Star With Two Small Worlds
Kepler-887 is a single star located 2890 light-years away, and two planets have been found orbiting it. The host star is estimated to be 3.09 billion years old, with a reported mass estimate of 1.19 solar masses, a reported radius estimate of 1.29 solar radii, and a temperature of 6190 K. Its mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
The two planets were both discovered by transit in 2016. Kepler-887 c is an Earth-like planet with a radius of 1.13 Earth radii, larger than Earth's, and an orbital period of 7.64 days. Kepler-887 b is a Super-Earth with a radius of 1.84 Earth radii, also larger than Earth's, and an orbital period of 20.4 days. Among the listed planets, Kepler-887 c has the shortest year and the smallest radius, while Kepler-887 b has the longest year and the largest radius, all by reported estimates.
