Researchers at Cornell University discovered that the temperature of WASP-76b, which has been called the "Planet of Hell," is higher than initially thought in 2016 (4,400 degrees Fahrenheit).

They affirmed that part of the exo-planet evaporates iron from the intensity of heat, causing iron rain to fall from its sky, and winds like cinders, at a speed of 11.184 miles per hour.

Researchers observed the planet via the Gemini North observatory near the summit of Mount Manoa Key in Hawaii, and discovered that the temperature on the planet's floor was 10,000 degrees Fahrenheit, and its atmosphere is saturated with calcium ions.

The planet is estimated to be one and a half times the size of the sun, and it does not move or rotate like other planets. It is said to be 640 light years away from Earth.
