4 rocky exoplanets found around Barnard's Star, one of the sun's nearest neighbors
The planets are all too hot for life as we know it, but astronomers haven’t given up searching for more planets in Barnard's Star's habitable zone.
Four small rocky planets confirmed orbiting nearby Barnard's star
Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - though they concluded that all of them are too hot to harbor life, much like our solar system's innermost planet Mercury.
4 Tiny Planets Found Orbiting Earth's Closest Solitary Star
Considered a solitary star for its lack of stellar companions, Barnard's Star is notoriously lonely—signs of any exoplanets in its orbit have come and gone without reliable evidence. But today, astronomers know the star is in good company.
Four tiny planets are orbiting one of our nearest stars
Astronomers have revealed new evidence that not just one, but four tiny planets are circling around Barnard's Star, the second-nearest star system to Earth.
Four small planets discovered around one of the closest stars to Earth – an expert explains what we know
Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it is too faint to be seen with the naked eye. Now, four small planets have been found orbiting the star.
