Astronomers will find a frozen superterror near our solar system
The International Team has discovered the frozen Super Earth orbiting the second nearest star system or closest star of our Sun, according to a study published on Wednesday in Nature.
The cold planet revolves around Bernard's star, our fourth closest neighboring star in general, after the triple Alpha Centauri system. Star Bernard, just six light-years from the Earth, is smaller and older than our Sun and is one of the least active active red dwarves.
Astronomers spread data from seven instruments, including the Planet Finding spectrograph on the Magellan II telescope at the Carnegie Institution for Science in Washington DC.
"After a very careful analysis we have over 99% confidence that the planet is there," said lead author Ignasi Ribas of the Department of Space Studies in Catalonia, Spain.
The Barnard Observatory, called the "Barnard" star, has a planet of at least 3.2 times the Earth and circulates its star every 233 days at a distance where the water will freeze. Researchers estimated the surface temperature minus 150 degrees Celsius.
Using radial velocity techniques, astronomers have detected small movements that gravitate the planet into the orbit of the stars.
They said that the newly discovered planet's characteristics led him to an excellent target for direct imaging with the next generation of devices, such as NASA's Wide Field Infrared Inspection Telescope (WFIRST).
