Gliese 682 or GJ 682 is a red dwarf. It is listed as the 53rd-nearest known star system to the Sun,[8] being 16.3 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.[4] 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.

Two candidate planets were detected orbiting Gliese 682 in 2014, one of which would be in the habitable zone.[9][10] However, a 2020 study did not find these planets and concluded that the radial velocity signals were probably caused by stellar activity.[11]

*[Primary]: Primary member of a system is the brightest one (and, in most cases, also the most massive one).
*[rest]: 8 planets; over 1,100,000 minor planets (including 5 dwarf planets); over 5000 comets; 206 moons of planets; over 200 moons of minor planets (including 9 moons of dwarf planets); bodies of planetary rings (mostly were observed rings, not separate bodies, but over 150 moonlets were observed); numerous small bodies, observed as meteors and meteorites, but not catalogued as minor planets or comets; spacecraft; space debris; cosmonauts. Some known comets and spacecrafts, currently located within Solar System boundaries, are not gravitationally bound with the Sun, and therefore formally are separate (interstellar) objects.
