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,
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.
“Super-Earth” in planetary system shedding new light on planetary evolution
An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a Sun-like star, including an ultra-short period planet with one of the highest densities ever measured.
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.
Astronomers Confirm 4 Rocky Exoplanets in Earth’s Backyard, Just 6 Light-Years Away
The four exoplanets orbit Barnard’s Star so closely that their years last only a few Earth days. They are probably rocky and, given their proximity to the star, uninhabitable. In fact, the 2024 study estimates Barnard b’s surface temperature to be a balmy 257 degrees Fahrenheit (125 degrees Celsius).
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.
