“The hottest in the universe” … the discovery of a planet whose heat melts metals

Recently, astronomers discovered a planet that they believe is the hottest in the universe and has unique characteristics.

The planet TOI-1431b is 490 light-years from Earth, twice the size of Jupiter, and is hotter than the red dwarf stars in the Milky Way.

Commenting on the discovery, Brett Addison, an astrophysicist at the University of South Queensland in Australia, said: “The planet is like hell, with a daytime temperature of 2700 degrees Celsius and a nighttime temperature of 2300. It can’t having atmospheric life, “according to a newspaper. British Independent.

The temperature of the planet is higher than that of molten metals, which ranges from 200 degrees, while it is 1770 degrees for platinum and 1670 for titanium.

Among the things that distinguish the planet is also its sense of rotation, which is what Edison explains, saying: “If you look at the solar system, all the planets rotate in the same direction that the sun rotates and they will all position it. is in the same plane, while the orbit of this new planet tilts to the point where it moves Located in the opposite direction to the rotation of its host star. “

The planet TOI-1431b was monitored by the exoplanet survey satellite transiting NASA, and was also detected by the telescope of the Star Observation Network in the Canary Islands.
