Kepler-15 (also known as KOI-128 or KIC 11359879 [5] [6] is a G-type main sequence star with a mass of 1.018 solar masses and a radius of 1.253 solar radius. The star lies at a temperature of 5595 Kelvin. [7]
Kepler-15 is orbited by one known planet named Kepler-15b, a hot jupiter enriched in heavy elements. It was discovered by the transit method in 2011. [2]
