The following is a list of 456 extrasolar planets that were only detected by

radial velocity method Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in t ...

–– 31 confirmed and 323 candidates, sorted by orbital periods. Since none of these planets are transiting or directly observed, they do not have measured radii and generally their masses are only minimum. The

true mass In astronomy, minimum mass is the lower-bound calculated mass of observed objects such as planets, stars and binary systems, nebulae, and black holes. Minimum mass is a widely cited statistic for extrasolar planets detected by the radial veloci ...

astrometry Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. It provides the kinematics and physical origin of the Solar System and this galaxy, the Milky Way. His ...

calculates the inclination of the orbit. There are 160 members of the multi-planet systems –– 21 confirmed and 139 candidates.

List of confirmed extrasolar planets

The most massive confirmed exoplanet is Iota Draconis b, which masses 9.40 M_J (i.e. 9.4 times the mass of Jupiter); the least massive confirmed planet is

Gliese 581 e Gliese 581e or Gl 581e is an extrasolar planet orbiting within the Gliese 581 system, located approximately 20.4 light-years away from Earth in the Libra constellation. It is the third planet discovered in the system (fourth if the disputed plane ...

, which masses 0.007906 M_J or 2.51 M_🜨. The longest period of any confirmed exoplanet is 55 Cancri d, which takes 5169 days or 14.15 years to make one trip around the star; the shortest period is

Gliese 876 d Gliese 876 d is an exoplanet approximately 15 light-years away in the constellation of Aquarius. The planet was the third planet discovered orbiting the red dwarf Gliese 876. It was the lowest-mass extrasolar planet apart from the pulsar planets o ...

, which takes just 1.938 days or 46.5 hours to orbit the star. ''Yellow rows denote the members of a multi-planet system''

List of extrasolar planet candidates

The most massive exoplanet candidate is HD 217786 b, which masses 12.98 M_J; the least massive confirmed planet is HD 10180 b, which masses 0.004 M_J or 3.1 M_🜨. The longest period of any confirmed exoplanet is

47 Ursae Majoris d 47 Ursae Majoris d (sometimes abbreviated 47 Uma d) is an extrasolar planet approximately 46 light-years away in the constellation of Ursa Major. The planet was discovered located in a long-period orbit (38 years) around the star 47 Ursae Majoris. ...

, which takes 14002 days or 38.33 years to make one trip around the star; the shortest period is HD 156668 b, which takes just 1.26984 days or 31.162 hours to orbit the star. ''Yellow rows denote the members of a multi-planet system''
