Discovered in 2004, 55 Cancri e (also called Janssen), was the first Super Earth to be discovered: it has a mass 8.6 times that of Earth and a radius about twice that of our planet. It orbits the star 55 Cancri in less than one Earth day. It is located about 40 light years away from us. The light curve was obtained with the Galhassin Robotic Telescope 2 (GRT2) as part of the ExoClock observational program (2020.10.11). Credits: GAL Hassin/Carmelo Falco

WASP-76b is a giant exoworld, about 640 light-years away in the constellation of Pisces. It has a permanent day side where temperatures soar above 2,400 degrees Celsius, high enough to vaporize metals like iron. Strong winds carry iron vapor to the cooler night side where it condenses into iron droplets.

Discovered in 2013, WASP-76b is a Hot Jupiter, a gas giant with a mass 0.92 times that of Jupiter and extremely hot: the temperature in the illuminated side of its star is about 2400 °C such that neutral iron is vaporized.
