A planet that is more than three times as large as the Earth, as it is called super-ground, has been found in an orbit around one of the nearest stars.
An example of how the planet will turn around Barnard's star.
The new planet discovered turns around the Barnard star, which lies at six distances of light years of the star, in a galactic perspective. This is the nearest second planet that has to be found.
The celestial body is described as having frozen and lighted a bit and goes around the star in 233 days. Barnard's star is a red star, and it is estimated to be almost twice as old as the sun. So, its light is much weaker, which has made it harder to discover the planet.
It also means that it receives around two percent so much energy from star to Earth as it goes from the sun. Therefore, it is estimated that the area temperature is less than 170 degrees Celsius.
– Definitely not in the living zone, no fluid water. If he has some water or gas, it's probably a solid form, so that's why we call the planet to freeze, said one of the researchers behind to the discovery, Ignasi Ribas at the IEEC Space Center in Spain.
The planet is 3.2 times as large as the ground, but it's hard to decide what the mass means.
"We have seen planets with this mass of stone, which can look like the ground with a solid surface, possibly with an atmosphere or some layers frozen at the top," he said Ribas.
– Or, it may be what we call mini-Neptun, as a gradual variation of gas gases in our solar system.
The only known planet closer to us is this is Proxima b, which lies on a light four years in the Alpha Centauri star system.
