Super-hot "hellish" exoplanet discovered "falling" on "its" star

The TESS Space Observatory, designedto search for exoplanets, she made another discovery of a planet with a unique climate and an unenviable fate. The exoplanet, called TOI-2109b, is located at a distance of 861 light years from the Sun and is located in the constellation Hercules, has a mass equal to 5 masses of "our" Jupiter and revolves around "its" star with a period of 16 Earth hours. In this case, the radius of the planet is only 1.35 of the radius of Jupiter.

The planet's climate can be imagined as "hellish" -the surface temperature heats up to 3300 degrees Celsius. For comparison: the melting temperature of steel is only 1400-1520 degrees, and only the melting temperature of tungsten (3400 degrees Celsius) is comparable to the temperature of the "hellish climate" of the planet TOI-2109b. The super-hot climate, according to astronomers, does not allow the formation of an atmosphere on the planet.

The high temperature on TOI-2109b is explained byблизким расположением планеты к «своему» Солнцу – желто-белому карлику, масса которого в 1,5 раза, а радиус – в 1,7 раза больше «нашего» Солнца. Предполагается, что «ночная» часть» планеты, благодаря отсутствию атмосферы, может быстро охлаждаться и каждые сутки на поверхности могут проходить сложные химические реакции, вызванные чудовищной разницей температур.

The fate of the planet TOI-2109b is sad enough -it rotates in a descending orbit and after 10 million years will finally "merge" with its star. Earthlings were lucky to find such a unique planet, because after a few Earth years, TOI-2109b cannot be detected even with the help of space telescopes, as its silhouette will merge with the bright background of the local star.
