Lalande 21185 is a red dwarf star (spectral class M2nV), located about 2.5 parsecs (8.21 light-years) from Earth, where it is visible in the constellation of Ursa Major. (ST reference: Spaceflight Chronology)

On several occasions in 2364, viewscreen readouts aboard the USS Enterprise-D showed the location of Lalande 21185, in the form of charts from the Enterprise library computer. (The Naked Now episodes: "The Last Outpost", "Conspiracy")

The Chronology depicted Lalande 21185's name and distance from Earth on star chart illustrations, but since it is a "real" star, modern scientists know a few things about its makeup that weren't in its Star Trek mentions. It is notable that Lalande 21185 was briefly glimpsed onscreen in canon productions of Star Trek because the production staff copied their star charts from the earlier, non-canon Chronology. Neither real observations nor the Chronology info has specified whether or not there is a star system associated with this body.
