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.
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.
For instance, they believe that it rains diamonds on those planets -- diamonds that sink into their interior and form a sparkly crust around their solid cores. Since it might take a long time ...
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]
A proposal that diamonds may also form in Jupiter and Saturn, where the concentration of carbon is far lower, was considered unlikely because the diamonds would quickly dissolve. [16] Experiments looking for conversion of methane to diamonds found weak signals and did not reach the temperatures and pressures expected in Uranus and Neptune.
