Found the nearest planet capable of supporting life
Astronomers from Australia have discovered the nearest potentially habitable planet located outside the Solar system.
Discovered planet is located at the distance of only 14 light years from Earth and about four times more massive than her. It is one of three planets orbiting a red dwarf called Wolf 1061.
“This is a very interesting finding, because all three planets have a relatively small mass to be rocky objects with a solid surface. Planet Wolf 1061c and does amazing as it is located in the “habitable zone” where liquid water and even different forms of life,” says the study’s lead author Duncan Wright from the University of New South Wales.
For their work, the team used the HARPS spectrograph mounted on the 3.6 meter telescope of the European southern Observatory (ESO) in La Silla, Chile.
Need to mention that Wolf 1061 is not the closest star around which planets were discovered. However, it is around 1061 Wolf discovered a rocky planet, and one of them is located in the “habitable zone”.
Three discovered planets revolve around a relatively small, cool star about every 5, 18 and 67 days.Their mass of at least 1.4, 4.3 and 5.2 times greater than the mass of the Earth respectively.
The largest planet is located in the vicinity of the external boundaries of the “habitable zone” and most likely has a hard surface. The smaller a planet is too close to the star, so the presence of her life in the form which we know as mercury, is impossible.
The new study is in the Astrophysical Journal Letters.
A small rocky planet with a solid surface like our Earth, are not so rare. However, their study is quite challenging, since they removed hundreds and thousands of light-years away.
The exception is Gliese 667Cc, which is located at a distance of 22 light years from Earth. It revolves around a red dwarf star every 28 days and at least 4.5 times the mass of Earth.
