55 Cancri e (abbreviated 55 Cnc e, also known as Janssen / ˈ dʒ æ n s ən /) is an exoplanet orbiting a Sun-like host star, 55 Cancri A.The mass of the exoplanet is about eight Earth masses and its diameter is about twice that of the Earth.
Because the companion to PSR J1719-1438 is planet-sized, made primarily of carbon (with an unknown amount of oxygen), and very dense, it may be similar to a large diamond. In the science press, the object has been called the "Diamond Planet". [4] [5] [6]
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.
Kepler-70b and Kepler-70c are often described as the hottest known exoplanets, both at >6800 K (assuming an albedo of 0.1 for both), [46] but their existence are highly doubtful. [47] [48] Hottest (self-luminous) GQ Lupi b: GQ Lupi: 2650 ± 100 K [49] (2377 °C) GQ Lupi b may be either a massive planet or a brown dwarf. [49] Coldest: OGLE-2005 ...
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]
This planet was the first known exoplanet to be discovered with the transit method. The object was discovered by the OGLE project, announced on July 5, 2002 [2] and confirmed on January 4, 2003 by the Doppler technique. [3] The period of this confirmed planet was the shortest until the confirmed discovery of WASP-12b on April 1, 2008. [4]
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.
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.
