Location of Gliese 682 in the constellation Scorpius

Gliese 682 or GJ 682 is a red dwarf. It is listed as the 49th-nearest known star to the Sun, being about 16 light years away from the Earth. Even though it is close by, it is dim with a magnitude of 10.95 and thus requires a telescope to be seen. It is located in the constellation of Scorpius, near the bright star Theta Scorpii.[1] The star is in a crowded region of sky near the Galactic Center, and so appears to be near a number of deep-sky objects from the Solar System's perspective. The star is only 0.5 degrees from the much more distant globular cluster NGC 6388.
