List of stars with confirmed extrasolar planets
Encyclopedia : L : LI : LIS : 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).
There are 197 planets listed—45 in multiple planet systems, 144 in single planet systems, 5 orbiting pulsars, 1 brown dwarf, and 2 free floating.
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.

Single planet systems
"Single" here means that only one planet has been detected to date. Since detection methods are not sensitive to low-mass planets, these stars may have smaller planets that are below the limits of detectability, or are so far from the star that they have not yet been observed over an orbital period. There are currently 144 known planets in single-planet systemsSorted by increasing mass.

Note:
(1) Transit detected, absolute mass of the planet.
(2) Planet found by gravitational lensing method.
(3) Another planet suspected.
(4) Planet imaged, mass derived from surface temperature of the planet.
(5) All the proper names are totally unofficial and not used in the scientific literature.
(6) Projected distance onto our line of sight possibly much larger
(7) Semimajor axis and minimum mass of the planet depend on the mass of the star.
