Kepler-63

Kepler-63 is a G-type main-sequence star located in the constellation Cygnus, approximately 850 parsecs (2,800 light-years) from Earth. It is slightly more massive and larger than the Sun.

Kepler-63 is notable for hosting a confirmed exoplanet, Kepler-63b, a hot Jupiter discovered by the Kepler space telescope using the transit method. This planet has a relatively low density for its size and proximity to its star.

Furthermore, observations of Kepler-63 have revealed evidence suggesting the presence of a circumplanetary disk around Kepler-63b. This disk is composed of gas and dust, and is considered a potential site for the formation of exomoons. The system is therefore of particular interest to astronomers studying planet formation and the evolution of planetary systems, especially in understanding the processes by which moons might form around exoplanets. Further observations are required to fully characterize the Kepler-63 system and confirm the properties of the circumplanetary disk.
