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


A planet the size of Mars and the composition of Mercury was discovered at a distance of 31 light years from the Sun. In 2019, TESS recorded an area of ​​the southern sky that included the star GJ 376. The distance at which the planet is from the Sun is very small by cosmic standards, which allowed astronomers to determine its characteristics. 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. 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. What is known about the discovered planet? Scientists analyzed the data and found a transit object with an ultra-short eight-hour orbit. 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. As a result, the daytime side of the planet warms up to 1500 degrees Celsius. How did you find the new 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. Thus, a year on this planet lasts eight hours. This telescope is used to observe changes in the brightness of nearby stars. The planet was named GJ 367 b. It turned out to be one of the lightest planets discovered to date. mit.edu/2021/tess-exoplanet-orbit-dwarf-star-1202

However, scientists believe that there is a possibility that the planet has habitable neighbors. The size of the planet GJ 367 b is comparable to Mars. This is stated in an international study of astronomers, published in the journal Science. Sources :
