List of stars with confirmed extrasolar planets

Extrasolar planets were first confirmed to be orbiting pulsars PSR B1257+12 and PSR B1620-26. These discoveries were announced in 1992 and 1993 respectively. The first extrasolar planet to be found orbiting a normal star, 51 Pegasi b, was first discovered to be orbiting 51 Pegasi in 1995.

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 assume arbitrarily 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).

There are 264 planets listed — 251 orbiting normal stars (61 in multiple planet systems, and 190 in single planet systems), 4 orbiting pulsars, and 1 orbiting a brown dwarf. 252 planets were found by radial velocity or doppler method, 31 were found by transit method, 1 by direct imaging, and 5 by timing method.
