Revision as of 12:43, 1 March 2005

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 x 10 kg) or multiples of Earth's mass (ME = 5.9737 x 10 kg), and have approximate distances in astronomical units (1 AU = 1.496 x 10 km, distance between Earth and Sun) from their parent stars. For more information on how planets may be detected, see extrasolar planet.
