Main Sequence Stars

The following is a list of main sequence stars with confirmed extrasolar planets. Note that the masses of the planets are lower bounds only. If a planet is detected by the spectral line displacement 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), and some also have approximate distances in astronomical units (1 AU = 1.496 x 10 km) from their parent stars.

Other Stars

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 some also have approximate distances in astronomical units (1 AU = 1.496 x 10 km) from their parent stars.


StarMass of planet, distance from primary, and orbital period
(if known)
PSR B1620-26PSR B1620-26c: (2.1 MJ) (23 AU) (100 years)
PSR 1257+12 PSR 1257+12 A: (0.015 ME) (0.19 AU) (25.34 days)
PSR 1257+12 B: (3.4 ME) (0.36 AU) (66.54 days)
PSR 1257+12 C: (2.8 ME) (0.47 AU) (98.22 days)
