Kepler-603 and Its Three Planets
Kepler-603 is a star 5020 light-years away with three planets. It is 4.37 billion years old and has 1.01 solar masses, 1.01 solar radii, and a temperature of 5810 K. A light-year is a unit of distance, and solar masses and radii compare stellar mass and radius with the Sun.
The planets were all discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness.
Kepler-603 d is Earth-like, with a radius of 1.32 Earth radii and an orbital period of 6.22 days, the shortest year among the listed planets. Kepler-603 b is Neptune-like, with a radius of 2.65 Earth radii and an orbital period of 21.1 days, the second-shortest year among the listed planets. Kepler-603 c is Jupiter-like, with a radius of 6.5 Earth radii and an orbital period of 128 days, the longest year among the listed planets. Among the listed planets, Kepler-603 d has the smallest radius and Kepler-603 c has the largest. Each planet's reported radius estimate is larger than Earth's.
