Beta Pictoris c (abbreviated as β Pic c) is the second exoplanet discovered orbiting the young star Beta Pictoris, located approximately 63 light-years away from Earth in the constellation of Pictor. Its mass is around nine times that of Jupiter, and it orbits at around 2.7 astronomical units (AU) from Beta Pictoris, about 3.5 times closer to its parent star than Beta Pictoris b.[1] It has an orbital period of 1,200 days (3.3 years).[1] The orbit of Beta Pictoris c is moderately eccentric, with an eccentricity of 0.24.[4][5]
This exoplanet is notable for having been detected by three different methods: initially radial velocity,[1] then direct imaging[3] and astrometry.[6]
