An international team of astronomers has confirmed the existence of K2-415b, an Earth-sized exoplanet. She
The authors of a new study discovered maternalstar of the planet - K2-415, analyzing data from the Kepler telescope. They confirmed the discovery by studying data from the TESS (Transiting Exoplanet Survey Satellite) satellite. This is a space telescope designed for the discovery of exoplanets by the transit method, developed by the Massachusetts Institute of Technology as part of NASA's Minor Research Program.
It turned out that the planet K2-415b revolves aroundred M-dwarf—a small, cool star. Objects of this type are more common than others in the Milky Way. A red dwarf is a small and relatively cool main sequence star with a spectral class of M. They are quite different from other stars. The diameter and mass of red dwarfs does not exceed a third of the solar mass (the lower limit of the mass is 0.0767 solar, followed by brown dwarfs).
While studying K2-415b, scientists discovered that its sizevery similar to Earth's, although the mass of the exoplanet is much greater. It also orbits much closer to the star than the Earth around the Sun. K2-415b takes only four Earth days to complete one revolution.
Scientists believe that due to such a close orbitThe planet has unsuitable conditions for life, despite the fact that the host star is much cooler than the Sun. But astronomers believe that the planet has an atmosphere, which means it is suitable for further research. Scientists also hope that there may be other planets around the host star.
