Moscow, February 8, 2016, 22:42 – REGNUM The astronomers found that the planet is in the constellation of Aries is a celestial body, like the Earth, based on the obtained values of the mass, according to an article on the site of Cornell University library.
Researchers in recent years have found outside the solar system are many planets sizes, several times higher than the earth. Last year, it was assumed that all the extrasolar planets whose radius exceeds the Earth more than 1.6 times, is a “mini-Neptune,” ie, the likes of the gas giants, in contrast to the smaller diameter of the “super-Earths” – planets, presumably having a dense structure.
However, the analysis of the planet in a star system BD + 20 594, similar to the Sun and located at a distance of 500 light years from Earth, has denied this theory. Researchers from the Catholic University of Chile in Santiago using the HARPS spectrograph specified mass of the planet. It was found that the planet density is about 7.9 grams per cubic centimeter at the earth’s diameter exceeding twice the mass of earth and – 16 times. That is discovered planet is still “super-Earth”, and not “mini-Neptune».
Due to the lack of atmosphere life on this planet will most likely does not exist. However, the discovery of BD + 20594b the planet could help scientists understand the characteristics of different planets and to increase the possibility of detecting planets similar to Earth.
