Scientists have discovered three new rocky planets the size of the Earth, one of which with a great ability to support life, gravitating around a star about 12 light-years away.
The masses of the three exoplanets represent at least 1.4 to 1.8 times that of the Earth, and their red dwarf star Gilese 1061 orbits every three to 13 days.
The star is 12 light-years away, making it the 20th star of the solar system.
The three planets discovered around the red dwarf are called Gliese 1016b, Gliese 1016c and Gliese 1016d.
The outer rocky planet, Gliese 1016 d, would have the most pleasant qualities to live in, located in the habitable stellar region, where temperatures allow the presence of liquid water on the surface.
Unfortunately, red dwarfs such as those around them can be turbulent and strike their environment with stellar and radiological radiation.
This means that if the planet Gliese 1016 d does not bear any life, its star can kill it or make life impossible.
The star Gilese 1061 seems relatively quiet compared to red dwarfs, but that does not mean that it was always like that.
The three planets were discovered using radial velocity or a method of "wobbling" based on a slight change in the wavelength of light emitted by a celestial body passing through its star and modifying the amount of light released by the star.
Astronomers continue to search for exoplanets in the hope of finding conclusive evidence of a "life" outside our solar system. (RT)
