Hot atmospheres could have iron rain, [107] molten-glass rain, [108] and rain made from rocky minerals such as enstatite, corundum, spinel, and wollastonite. [109] Deep in the atmospheres of gas giants, it could rain diamonds [ 110 ] and helium containing dissolved neon.
PSR J1719−1438 b is an extrasolar planet that was discovered on August 25, 2011, in orbit around PSR J1719−1438, a millisecond pulsar.The pulsar planet is most likely composed largely of crystalline carbon but with a density far greater than diamond.
55 Cancri d (abbreviated 55 Cnc d), formally named Lipperhey / ˈ l ɪ p ər h iː /, is an extrasolar planet in a long-period orbit around the Sun-like star 55 Cancri A.Located at a similar distance from its star as Jupiter is from the Sun, it is the fifth and outermost known planet in its planetary system. 55 Cancri d was discovered on June 13, 2002.
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.
This is the first time the atmosphere of a super-Earth exoplanet was analyzed successfully. [31] [32] In November 2017, it was announced that infrared observations with the Spitzer Space Telescope indicated the presence of a global lava ocean obscured by an atmosphere with a pressure of about 1.4 bar, slightly thicker than that of Earth.
Alpha Centauri is the target of several exoplanet-finding missions, including Breakthrough Starshot and Mission Centaur, the latter of which is chronicled in the 2016 documentary film The Search for Earth Proxima. [12] In 2023, astronomers used the radial velocity method to confirm that the exoplanet Wolf 1069 b sits in the habitable zone of ...
The exoplanet closely orbits its host star, and the intense heat and radiation received from that sun-like star — more than 4,000 times the amount of radiation that Earth gets from our sun ...
The IAU's names for exoplanets – and on most occasions their host stars – are chosen by the Executive Committee Working Group (ECWG) on Public Naming of Planets and Planetary Satellites, a group working parallel with the Working Group on Star Names (WGSN). [1] Proper names of stars chosen by the ECWG are explicitly recognised by the WGSN. [1]
