Kepler-1177 is a star with 0.98 times the mass of the Sun, and 0.97 times its radius. It is located 4239.93 light years away from the solar system and is estimated to be 4.47 billion years old, as compared to the Sun which is roughly 4.6 billion years old.
Kepler-1177 is known to have 1 exoplanets in orbit around it.
Kepler-1177 b was discovered by the Kepler observatory, in 2016-05, using the transit method. Its semi-major axis is 0.43 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of Kepler-1177 b is 4.261 times the mass of Earth. The radius of Kepler-1177 b is 1.900 that of Earth. With a mass below 5 Earth masses, a density of 3.42, and a semi-major axis of 0.4301 astronomical units, Kepler-1177 b could, potentially, be an ocean world - a planet with no dry land.
