Kepler-277
Kepler-277 is a large yellow star about 961 ± 10 parsecs (3,134 ± 33 ly) away in the constellation of Lyra. It is 1.69 R☉ and 1.12 M☉, with a temperature of 5946 K, a metallicity of -0.315 [Fe/H], and an unknown age.[3] For comparison, the Sun has a temperature of 5778 K, a metallicity of 0.00 [Fe/H], and an age of about 4.5 billion years. The large radius in comparison to its mass and temperature suggest that Kepler-277 could be a subgiant star. Planetary system
Kepler-277bKepler-277b (KOI-1215.01) is the second most massive and third-largest rocky planet ever discovered,[improper synthesis?] with a mass close to that of Saturn. It was discovered in 2014. Kepler-277b orbits close to its host star, with one orbit lasting 17.324 days.[3] Kepler-277cKepler-277c (KOI-1215.02) is the third most massive and second-largest rocky planet ever discovered,[improper synthesis?] with a mass about 64 times that of Earth. It was discovered in 2014. Kepler-277c orbits close to its host star, with one orbit lasting 33.006 days.[3] See alsoReferences
