CVSO 30 (PTFO 8-8695) is a T Tauri star, located in constellation Orion at 1200 light years from Earth away with two candidate planets (CVSO 30 b and CVSO 30 c). Both candidate planets are gas giants. It is the first star around which potential planets have been found both by the transit method and by direct imaging.

CVSO 30 b is calculated to have a period of 10.76 hours (0.008 AU) and CVSO 30 c a period of 27,000 years (660 AU). It is a hot Jupiter candidate planet orbiting the T Tauri star, with 6.2 Jupiter masses.[4]

Direct imaging of CVSO 30 c, with 4.7 Jupiter masses, has been achieved through photometric and spectroscopic high contrast observations carried out with the Very Large Telescope located in Chile, the Keck Observatory in Hawaii and the Calar Alto Observatory in Spain.[5]
