The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods, such as the transit method and the radial-velocity ...
Among the 1,235 possible extrasolar planet candidates detected by NASA's planet-hunting Kepler space telescope during its first four months of operation, 54 are orbiting in the parent star's habitable 'Goldilocks' zone where liquid water could exist. [41]
A recent study of an exoplanet 120 light-years away revealed it has elements that are believed to be essential in the formation of life.. NASA studied K2-18 b, an exoplanet 8.6 times as massive as ...
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
In 1995, astronomers using ground-based observatories discovered 51 Pegasi b, the first exoplanet orbiting a Sun-like star. [7] NASA launched the Kepler space telescope in 2009 to search for Earth-size exoplanets. By 2015, they had confirmed more than a thousand exoplanets, [note 1] while several thousand additional candidates awaited ...
HIP 116454 b, or K2-2 b, [2] is an exoplanet orbiting the star HIP 116454, 62 parsecs (201 ly) from Earth toward the constellation Pisces. It is 32,000 kilometres (20,000 mi) in diameter and 12 times as massive as Earth. [3] [4] It was discovered by the NASA Kepler spacecraft, and is the first exoplanet discovered during Kepler 's K2 mission. [5]
Gliese 367 b, formally named Tahay, [2] is a sub-Earth exoplanet orbiting the red dwarf star Gliese 367 (GJ 367), 30.7 light-years (9.4 parsecs) from Earth in the constellation of Vela. [5] The exoplanet takes just 7.7 hours to orbit its star, one of the shortest orbits of any planet. [1]
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 ...
