| Posted: 03 Jun 2014 04:40 PM PDT Astronomers have discovered two new planets orbiting a very old star that is near to our own sun. One of these planets orbits the star at the right distance to allow liquid water to exist on its surface, a key ingredient to support life. Kapteyn's Star, named after the Dutch astronomer, Jacobus Kapteyn, who discovered it at the end of the 19th century, is the second fastest-moving star in the sky and belongs to the Galactic halo, an extended group of stars orbiting our Galaxy on very elliptical orbits. With a third of the mass of the Sun, this red-dwarf can be seen with an amateur telescope in the southern constellation of Pictor. |
