WASP-76b

WASP-76b is a hot Jupiter exoplanet discovered during 2013 that can be found in the constellation Pisces. It orbits a F-type star BD+01 316 (WASP-76) and has a size 0.92 that of Jupiter's mass. In March 2020, it was speculated the temperature on the planet could reach on the hot side, hot enough to vaporize neutral iron. If the night side of WASP-76b had temperatures down to at least , the iron may condense then rain down as hot liquid iron on its surface. 
The planet equilibrium temperature is , yet measured dayside temperature is still hotter at .
Study shows that WASP-76b seems to be the only planet in its solar system.
In May 2020, it was discovered what the previous spectra of WASP-76b, taken by the Hubble Space Telescope, were distorted by the light from a suspected stellar companion. Therefore, updated atmospheric model is cloudy hydrogen-helium envelope, non-detection of alternatively reported neutral iron (including "iron rain"), and only upper limits on oxides of titanium and vanadium. Combination of data from the Hubble and Spitzer space telescopes have allowed to detect titanium oxide and traces of water in atmosphere of WASP-76b though. Later, higher resolution spectrum, has features of ionized Li, Na, Mg, Ca, Mn, K, and Fe, but no ionized Ti, Cr, Ni, or molecular oxides of titanium, vanadium or zirconium were found.
The atmosphere of WASP-76b is cloudy and mostly grey, with a significant amount of thermal incandescence.
