Astronomers found a 'cold super-Earth' less than 6 light-years away — and it may be the first rocky planet we'll photograph beyond the solar system



  • Astronomers think they've found a "cold super-Earth" exoplanet orbiting Barnard's star.
  • Barnard's star, less than six light-years from us, is the closest single-star system to our sun.
  • The new world, called Barnard's star b, or GJ 699 b, is at least 3.2 times as massive as Earth.
  • It orbits in its parent star's "snow line," a region at the edge of a star'shabitable zone where scientists suspect most rocky planets form.
  • This roughly Earth-size exoplanet may be the first to be photographed by a new generation of powerful telescopes.

1% chance of detection with Gaia. 10% chance if they put some HST time to it. If HST does not detect it, then an upper mass of 8 Earth-masses can be obtained. WFIRST may have a ~99% chance of detecting it.

Prospects for detecting the astrometric signature of Barnard's Star b
