Kepler-268: A Distant Star With Two Neptune-Like Worlds

Kepler-268 is a star located 2780 light-years away. It has 2 known planets, both discovered by the transit method in 2014. The transit method detects a planet when it passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods.

The host star is 3.8 billion years old and has a reported mass of 1.13 solar masses, a radius of 1.22 solar radii, and a temperature of 6060 K. Its mass and radius estimates are larger than the Sun's, and its temperature is hotter than the Sun's.

Kepler-268 b and Kepler-268 c are both Neptune-like planets. Kepler-268 b has an orbital period of 25.9 days and a radius of 2.55 Earth radii. Kepler-268 c has an orbital period of 83.4 days and a radius of 3.38 Earth radii. Both planets are larger than Earth in radius. Among the listed planets, Kepler-268 b has the shortest year and the smallest radius, while Kepler-268 c has the longest year and the largest radius.
