A sun-like star in our solar system's backyard may host five planets, including one perhaps capable of supporting life as we know it, a new study reports. Astronomers have detected five possible alien planets circling the star Tau Ceti, which is less than 12 light-years from Earth - a mere stone's throw in the cosmic scheme of things. 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. With a minimum mass just 4.3 times that of Earth, this potential planet would be the smallest yet found in the habitable zone of a sun-like star if it's confirmed, researchers said. '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.' 'They are everywhere, even right next door.'
