[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] Beta Pictoris c is a super-Jupiter, an exoplanet that has a radius and mass greater than that of the planet Jupiter.
[9] Beta Pictoris c was detected indirectly, through 10 years of observation[10] of radial velocity data from the High Accuracy Radial Velocity Planet Searcher (HARPS) spectroscope on the European Southern Observatory's ESO 3.6 m Telescope at La Silla Observatory in Chile by a worldwide team led by Anne-Marie Lagrange, as the discovery of the planet was publicly announced in August 2019.
[11] The European Southern Observatory confirmed the presence of Beta Pictoris c, on 6 October 2020, through the use of optical interferometry.
[3] With a semi-major axis of approximatively 2.7 astronomical units, Beta Pictoris c is, as of 2020, the closest extrasolar planet to its star ever photographed.
