Gliese 682 or GJ 682 is a red dwarf star and is listed as 49th nearest star to the Sun, being about 16 light years away from the Earth. Even though it is close by, it is dim with an magnitude of 10.95 and thus requires a relatively powerful telescope to be seen. It is located in the constellation of Scorpius, near the bright star Theta Scorpii.[1] It has two candidate planets, one of which is in the habitable zone. [3][4]
