|} Groombridge 1618 is a star in the constellation Ursa Major. It is located relatively close to Earth, at a distance of 15.85 light years. This is an orange main sequence dwarf of spectral type K7.0V.

It is a flare star with behavior similar to UV Ceti. The chromosphere has been shown to be active and possesses star spots comparable to a Sun spot. It has a greater luminosity than most flare stars, which are typically red dwarfs, but is less active. The level of activity may suggest that this is a somewhat youthful star.
