The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth -- a so-called super-Earth. One of the largest observing campaigns to date using data from a world-wide array of telescopes has revealed this frozen, dimly lit world. The newly discovered planet is the second-closest known exoplanet to the Earth. Barnard's star is the fastest moving star in the night sky.
