Kepler-903 and Its Two Worlds
Kepler-903 is a star located 4470 light-years away, and two planets have been found in its orbit. The host star is 4.79 billion years old and contains 0.98 solar masses, with a radius of 0.97 solar radii. Its temperature of 5680 K is cooler than the Sun's.
Both planets were discovered by the transit method in 2016, which detects the small dip in a star's brightness when a planet passes in front of it. Kepler-903 b is a Super-Earth with a radius of 2.01 Earth radii and an orbital period of 10.4 days, giving it the shortest year among the listed planets. Kepler-903 c is Neptune-like, with a radius of 2.53 Earth radii and an orbital period of 62.9 days, the longest year among the listed planets. Both planets have radii larger than Earth's, and Kepler-903 b has the smallest radius among the listed planets while Kepler-903 c has the largest.
