Gliese 876 (or Gl 876 , IT Aquarii , Ross 780 ) is a star located in the Constellation of the Verseau.

It is about a Naine red three times less massive than the Sun (either approximately 200 times the Masse of Jupiter). It is also considerably less luminous: approximately 600 times less than the Sun. Moreover, distant of only 15 light-years, it is very close to the Sun: it is about the 40^e star nearest to our Solar system (if only the stellar systems are counted; the 53^e by counting the individual components of the multiple systems). In spite of its proximity, it is too much weak to be visible with the naked eye, one needs at least small a Télescope to be able to observe it.

Gliese 876 has three planets:

• Gliese 876 D, a telluric Planet giant (7,3 times terrestrial mass)
• Gliese 876 C, a gas Giant (0,56 times the mass jovienne)
