Kepler-1093 and Its Two Super-Earths

Kepler-1093 is a star located 3500 light-years away, and two planets have been found in orbit around it. Both were detected by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish orbital periods. The host star is 2.95 billion years old, with a reported mass estimate of 1.13 solar masses, a reported radius estimate of 1.2 solar radii, and a temperature of 6170 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.

Both worlds are Super-Earths, a size class that reaches up to 2.5 times Earth's radius. Kepler-1093 b has a radius of 1.95 Earth radii and an orbital period of 25.1 days, while Kepler-1093 c has a radius of 1.96 Earth radii and an orbital period of 89.7 days. Each planet's reported radius estimate is larger than Earth's, and among the listed planets Kepler-1093 b has the shortest year by reported estimates, at 25.1 days, as well as the smallest radius, at 1.95 Earth radii. Kepler-1093 c has the longest year by reported estimates and the largest radius by reported estimates.
