- PARIS (AFP), and one of them is probably a world of volcanic molten rock - a bright star in astronomy, dwarf star orbiting in a planetary system with three super-Earth was found Thursday..
Four-planet system of the M-shaped constellation Cassiopeia in the northern hemisphere might be hiding, "only" 21 light years from Earth, in the journal Astronomy and Astrophysics group.The name of one of the giant orbiting a star called HD219134 and three super-Earth - it consists of four planets.Super-Earth to have a high mass, but gas giants like Neptune and Saturn or Jupiter than light. It's gas, rock, or both can be made.It is now the planet, HD219134b, almost every three days, keeping the pin low orbit, and the Earth seen from the point of view that has passed across the face of its star.NASA's Spitzer Space Telescope to measure the Earth's land mass 4.5 times greater than was shown, and it had a 1.6-fold.Was released by NASA on July 30, this artist who, Delivery, 2015 shows the site map of the sky with T ..."Probably the same configuration as well, which suggests the Earth, its average density close to the density," the astronomer who participated in the study, said in a news release from the University of Geneva.Said study co-author Stephane Udry told AFP, said: "It is very close to the temperature of about 700 degrees." Kelvin (427 ° C 0.800)."Maybe the surface of the magma beneath the volcano in the world with ... ... is not a good life."Its star, the so-called "habitable zone" was not, it would not be for life need liquid water.But another reason HD219134b exciting: it is the closest planet to cross the well-known scientist, and thus further study of composition and atmosphere against the backdrop of a star is a rare opportunity."The interest in this cross is the star light through the atmosphere (through research), the planet's atmosphere to allow the characterization of the system," said Audrey.21 light years away from Earth, relatively close to the system. In comparison, three light-years of our sun to the nearest star, and six second light.HD219134b his colleagues planets, and stars orbit weighs 6.8 days and 2.7 times the Earth up to the second, and 8.7 times more massive than the Earth in the next 47 days is with them.Giant planet orbits every three years, the team said.
