Astronomers have detected five possible alien planets, including one capable of supporting life as we know it, circling a sun-like star Tau Ceti, which is less than 12 light-years from Earth. One of the newfound worlds appears to orbit in Tau Ceti’s habitable zone, a range of distances from a star where liquid water can exist on a planet’s surface.
Steve Vogt, of the University of California, states that “This discovery is in keeping with our emerging view that virtually every star has planets, and that the galaxy must have many such potentially habitable Earth-sized planets.”
Researchers said that, the five planet are all relatively small, with minimum masses ranging from 2 to 6.6 times that of Earth. The possibly habitable world, which completes one lap around Tau Ceti every 168 days, is unlikely to be a rocky planet like Earth.
