Bernard's Star Has a Planet (Again)!


The red dwarf Barnard's Star is the closest single star to the Sun, only six light-years away. Astronomers have announced the discovery of a planet with half the mass of Venus, orbiting the star every three days. This puts it too close to be in the habitable zone, with a surface temperature of 125 °C. The team also found a hint of three additional planets in the system but will require further observations to pin down their sizes and orbits.
