Kepler-1038 and Its Two Planets
Kepler-1038 is a star located 1910 light-years away, and it hosts two known planets. The star is 4.27 billion years old and has a mass of 0.87 solar masses, a radius of 0.83 solar radii, and a temperature of 5340 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The two planets orbit Kepler-1038. Kepler-1038 b is a Neptune-like planet discovered by transit in 2016, with an orbital period of 148 days and a radius of 3.53 Earth radii. Kepler-1038 c is an Earth-like planet discovered by transit in 2021, with an orbital period of 7.13 days and a radius of 1.42 Earth radii. Both planets have reported radius estimates larger than Earth's.
Among the listed planets, Kepler-1038 c has the shortest year by reported estimates at 7.13 days and the smallest radius at 1.42 Earth radii. Kepler-1038 b has the longest year by reported estimates at 148 days and the largest radius at 3.53 Earth radii.
