Another Mercury, but great as the Earth

Scientists have discovered a planet very similar in size to Earth at a distance of 340 light years. According to them, it could clarify the peculiarities of the planet closest to the Sun. Tha planet discovered has two and a half times the mass of our planet, which makes it at last much denser and, in its overall composition, more like Mercury.

The planet K2-229 b pulled in the consideration of the group by the size fundamentally the same as the Earth. Be that as it may, its metal center is relied upon to make up 68% of the mass, contrasted with not as much as a third on account of Earth. As per Vardan Adibekyan (IA and Universidade do Porto), one of the creators of the examination, which added to the substance portrayal of the star K2-229, this outcome would not be normal considering the concoction organization of the parent star.

This star is somewhat more youthful and less monstrous than our Sun and has a marginally littler extent of other heavier components than hydrogen and helium. This confusion amongst star and planet is the first to be identified in an additional nearby planetary group, yet even on our doorstep in Mercury, something comparative happens.

“Earth, Mars, and Venus, similar to the Sun, share an indistinguishable relative plenitude of certain concoction components from iron, magnesium or silicon,” says Vardan Adibekyan. “Mercury is unique and it is suspected that some outer procedure has altogether changed its piece. Presently we have discovered a planet that has an indistinguishable disposition from having an unexpected synthesis in comparison to one would anticipate from the piece of its parent star.”

“The group trusts that the revelation of different planets of a similar sort may enable us to better comprehend is that planets like Mercury have shaped and developed. You can even supplement the mission information to this body at the internal edge of the Solar System, for example, Messenger and the future BepiColombo, which will be propelled for the current year.”

In fact, the similitudes with Mercury end here. K2-229b circles substantially nearer to its star, finishing one transformation in only 14 hours (one year on Mercury endures 88 Earth days). As of now its temperature amid the day is in excess of four times more noteworthy than the daytime face of the littlest planet of the nearby planetary group, having the capacity to achieve the 2000 degrees Celsius, enough to meld press.

In the K2-229 framework two different planets were recognized, K2-229 and K2-229 d. The planetary framework has been recognized through the information space telescope Kepler, the NASA and affirmed and portrayed with the spectrograph HARPS, the ESO.

For Susana Barros (IA and University of Porto), coauthor of the article and who contributed to the detection and characterization of the planet K2-229 b, it is part of a very interesting class of planets. “It’s Earth-like but it orbits extremely close to its star, something surprising since they do not exist in the Solar System. This is another excellent example of how the discovery of extrasolar planets can help us understand the formation of our solar system. ”
