List Of Stars With Confirmed Extrasolar Planets

The following are lists of stars with confirmed extrasolar planets. Note that the masses of the planets are (for the most part) lower bounds only. If a planet is detected by the radial velocity method, no information is gained about the inclination of the planet's plane of orbit around its star, and a value for this is needed to calculate the mass. It has become customary to arbitrarily assume that the plane is exactly lined up with the line of sight from Earth (this produces the lowest possible mass consistent with the spectral line measurements). The planets are listed with indications of their approximate masses as multiples of Jupiter's mass (MJ = 1.898 × 1027 kg) or multiples of Earth's mass (ME = 5.9737 × 1024 kg), and have approximate distances in astronomical units (1 AU = 1.496 × 108 km, distance between Earth and Sun) from their parent stars. For more information on how planets may be detected, see extrasolar planet. According to astronomical naming conventions, the official designation for a body orbiting a star is the star's catalogue number followed by a letter. The star itself is designated with the letter 'a', and orbiting bodies by 'b', 'c', etc. Some extrasolar planets have been given unofficial names, but these are not sanctioned by the International Astronomical Union which oversees astronomical naming, or used in the scientific literature.
