Likely larger than Poltergeist, but not confirmed as planet until 2003. First circumbinary planet, first planet to be found in a globular cluster and the oldest planet to be discovered (until 2020) at the age of 11.2–12.7 billion years old, [265] hence the nickname, "Methuselah". [264] [266] 1992 – 1995 Poltergeist (PSR B1257+12 c) Unknown: ←
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 [30] [b]), the most massive planets are those with true mass closest to that cutoff; if planets and brown dwarfs are differentiated based on formation ...
K2-38b, also designated EPIC 204221263 b, is a massive rocky exoplanet closely orbiting a Sun-like star and is one of the densest planets ever found.Discovered in 2016 by Crossfield et al. and later characterized by Sinukoff et al., K2-38b is a rocky super-Earth about 55% larger than Earth (nearly 20,000 km wide) but about 12 times more massive (around 7.2*10^25 kg, a bit less than Uranus ...
What is the largest planet ever discovered? The largest exoplanet (not including brown dwarfs, which are failed stars) is ROXs 42Bb, according to AZ Animals. This planet has a radius 2.5 times ...
TrES-4b is an exoplanet, one of the largest exoplanets ever found. It was discovered in 2006, and announced in 2007, by the Trans-Atlantic Exoplanet Survey , using the transit method . It is approximately 1,400 light-years (430 pc ) away orbiting the star GSC 02620-00648 , in the constellation Hercules .
Scientists have discovered a giant planet orbiting a massive pair of extremely hot stars, an environment previously thought too inhospitable for a planet to
Kepler-277b and Kepler-277c are a pair of planets orbiting the same star, both thought to be mega-Earths with masses of about 87.4 M E and 64.2 M E, and radii of about 2.92 R 🜨 and 3.36 R 🜨, respectively. [7] PSR J1719−1438 b is the most massive mega-Earth ever known with a mass of about 330 M E and a radius less than 4 R 🜨.
The planet is in a circumbinary orbit around the two stars of PSR B1620-26 (which are a pulsar (PSR B1620-26 A) and a white dwarf (WD B1620-26)) and is the first circumbinary planet ever confirmed. It is also the first planet found in a globular cluster. The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion ...
