Astronomers have discovered a low-mass "sub-Earth" planet orbiting the closest solo star to the solar system, Barnard's star, that has a year lasting just three Earth days.

The universe beyond our Solar System is vast and filled with mysteries, and some of its most fascinating secrets lie just beyond our cosmic doorstep. While the Sun is the closest star to Earth, it's ...

Astronomers have discovered a new exoplanet that may be habitable 35 light-years from Earth. Named L 98-59 f, it joins four ...

While Proxima Centaury is the closest known star to the Earth, at a distance of about 4.24 light-years, Bernard’s star is the closest single star to us.

Barnard's Star, also known as GJ 699, is of intense interest to planetary astronomers. The only stars closer to Earth are the Centauri trinary system. Barnard's star isn't just a lone star, like the ...

NASA's ISS-mounted X-ray telescope NICER has weighed and measured the closest pulsar to Earth. The neutron star PSR J0437 spins 174 times a second and has a mass of 1.4 suns.

If this interpretation is correct, the object is 250 to 1,000 light-years away. This would make Calvera one of the closest known neutron stars — possibly the closest.
