Earth, Light-Year and Tiny Planets

Four Tiny Planets Discovered Near Earth, After Century-Long Search
Astronomers have made an exciting breakthrough by discovering four sub-Earth exoplanets orbiting Barnard’s Star, our closest single-star neighbor. Using the high-precision MAROON-X instrument on the Gemini North telescope,
Astronomers Find Four Sub-Earth Planets Just Six Light-Years Away
Barnard’s Star has fascinated astronomers for decades. At just six light-years away, it is the second-closest single star to our own Sun. Now, two separate research teams have found solid evidence that four tiny planets—each less than half the mass of Earth—circle this nearby star at incredibly close distances.
Four Mysterious Alien Worlds Discovered Just 6 Light-Years from Earth!
Astronomers have detected four small planets orbiting Barnard’s Star, one of the closest stars to Earth, at just six light-years away. This discovery, published in The Astrophysical Journal Letters, marks a significant step in the search for rocky exoplanets beyond our solar system.
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.
Earth has new neighbors: Four planets discovered just 6 light years away
Exciting new research suggests there are four miniature planets orbiting Barnard’s Star, each thought to be just 20 to 30% the mass of Earth.
