The stars with the most confirmed planets are the Sun (the Solar System's star) and Kepler-90, with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets. The 1,033 multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d).
Planets from the Solar System were also included for comparison purposes. Discovered in 2006, OGLE-2005-BLG-390Lb is the coldest known exoplanet, and was nicknamed "Hoth" by NASA in reference to the planet from the Star Wars franchise. [1] All temperatures here are equilibrium temperatures.
Title Planet Star Data Notes Most massive The most massive planet is difficult to define due to the blurry line between planets and brown dwarfs.If the borderline is defined as the deuterium fusion threshold (roughly 13 M J at solar metallicity [29] [b]), the most massive planets are those with true mass closest to that cutoff; if planets and brown dwarfs are differentiated based on formation ...
There are 7,408 known exoplanets, or planets outside the Solar System that orbit a star, as of January 26, 2024; only a small fraction of these are located in the vicinity of the Solar System. [2] Within 10 parsecs (32.6 light-years ), there are 106 exoplanets listed as confirmed by the NASA Exoplanet Archive .
The bright giant star BD+20 2457 was proposed to host two super-Jupiter planets or brown dwarfs, although the claimed planetary system is not dynamically stable. [19] As BD+20 2457 is a halo star possibly having formed in the Gaia Enceladus, which are galactic remains of a former galaxy, the star and its planets might be extragalactic in origin ...
Astronomers say they have uncovered an unusual planet that’s about 50% bigger than Jupiter and somehow still the second lightest planet ever found.
A companion star may be destroyed during the interaction with a pulsar but leave a planet-sized remnant, [3] such a system is known as a "black widow". [14] Finally, it is possible that planets from companion stars or rogue planets are captured by a pulsar, [15] or that a pulsar merged with the original host star of the planets. [16]
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
