What new planet the size of Mars and with the composition of Mercury have scientists found?

The discovery of GJ 367 b around such a star indicates the possible presence of other planets in this system, which could help scientists understand the origin of GJ 376 b and other similar planets. At such extreme temperatures, any atmosphere would have evaporated long ago, along with any signs of life we ​​are used to. The planet was discovered by the Transiting Exoplanet Survey Satellite (TESS) space telescope. behind the planet's star using the High Accuracy Radial Velocity Planet Searcher (HARPS) in Chile. Since GJ 376 b is a short distance from its star, it receives 500 times more radiation than the Earth receives from the Sun. A planet the size of Mars and the composition of Mercury was discovered at a distance of 31 light years from the Sun. It turned out to be one of the lightest planets discovered to date. So, scientists found out that GJ 376 b & mdash; it is a rocky planet that may contain a solid core of iron and nickel, similar to the interior of Mercury. Sources :
https: //news. How did you find the new planet? She orbits her star in just eight hours. The core probably occupies 86% of the planet's interior. Its weight is 55% of the Earth's mass, radius & mdash; 72%. Scientists analyzed the data and found a transit object with an ultra-short eight-hour orbit. This is stated in an international study of astronomers, published in the journal Science. The thing is that her star & mdash; red dwarf or M-dwarf & mdash; they are a type of stars that usually have multiple planets. This telescope is used to observe changes in the brightness of nearby stars. Thus, a year on this planet lasts eight hours. The size of the planet GJ 367 b is comparable to Mars. What is known about the discovered planet? The study was carried out by scientists from the Institute for Planetary Research of the German Aerospace Center in collaboration with an international team of researchers. The distance at which the planet is from the Sun is very small by cosmic standards, which allowed astronomers to determine its characteristics. mit.edu/2021/tess-exoplanet-orbit-dwarf-star-1202

Истoчник aif.ru As a result, the daytime side of the planet warms up to 1500 degrees Celsius. However, scientists believe that there is a possibility that the planet has habitable neighbors. The planet was named GJ 367 b. In 2019, TESS recorded an area of ​​the southern sky that included the star GJ 376.
