Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.
Proper names of planetary systems often follow common themes – for example, the planets of the star Copernicus are named after European astronomers. Proper names for planets outside of the Solar System – known as exoplanets – are chosen by the International Astronomical Union (IAU) through public naming contests known as NameExoWorlds.
Motion is interpolated from annual observations. Comparison of the probable size of WASP-17b, an exoplanet in the constellation of Scorpius to Jupiter (on left) using approximate models of planetary radius as a function of mass. [1][2] An exoplanet or extrasolar planet is a planet outside the Solar System.
List of largest exoplanets. Jupiter as seen by Voyager 1 in 1979. It is the largest planet having its surface resolved [1][2] [3] and it is the largest planet in the Solar System. [4] Below is a list of the largest exoplanets so far discovered, in terms of physical size, ordered by radius.
As of June 16 2023, the Kepler space telescope and its follow-up observations have detected 2,778 planets, including hot Jupiters, super-Earths, circumbinary planets, and planets located in the circumstellar habitable zones of their host stars. [1][2][3][4] Kepler has detected over 3,601 unconfirmed planet candidates [5][6] and 2,165 eclipsing ...
The International Astronomical Union has assigned proper names to some known extrasolar bodies, including nearby exoplanets, through the NameExoWorlds project. Planets named in the 2015 event include the planets around Epsilon Eridani (10.5 ly) and Fomalhaut , [ note 4 ] [ 11 ] while planets named in the 2022 event include those around Gliese ...
This list of exoplanets discovered in 2021 is a list of confirmed exoplanets that were first observed in 2021. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information. Name. Mass (MJ)
The individual planet data pages also contain the data on the parent star, including name, distance in parsecs, spectral type, effective temperature, apparent magnitude, mass, radius, age, and celestial coordinates (Right Ascension and Declination).
