Kepler-730: A Distant Star With Two Known Planets
Kepler-730 is a star 6310 light-years away with two planets orbiting it. The star is 9.5 billion years old and has a mass of 1.05 solar masses, a radius of 1.41 solar radii, and a temperature of 5620 K. Its reported radius estimate is larger than the Sun's, while its reported temperature is cooler than the Sun's.
Both planets were found 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. Kepler-730 b is a Jupiter-like planet discovered in 2016, with an orbital period of 6.49 days and a radius of 12.3 Earth radii. Kepler-730 c is a Super-Earth discovered in 2018, with an orbital period of 2.85 days and a radius of 1.57 Earth radii. These size classes compare radius with Earth's: a Jupiter-like planet exceeds 4 times Earth's radius, while a Super-Earth reaches 2.5 times.
Among the listed planets, Kepler-730 c has the shortest year by reported estimates, at 2.85 days, and the smallest radius, at 1.57 Earth radii. Kepler-730 b has the longest year by reported estimates, at 6.49 days, and the largest radius, at 12.3 Earth radii.
