The alternative designation of Wolf 630 forms the namesake of a moving group of stars that share a similar motion through space.

[4][3] Both outer and inner orbits are nearly circular and, probably, coplanar[4][3] (in keeping with a general tendency of close triple systems).

The projected separation of the red dwarf from the primary triple system is about 220 arcsec,[4][3] corresponding at 21.05 light-years to 1420 a.u.

In 1984, the apparent detection of an infrared source near vB 8 suggested it had a low mass companion.

This discovery was later found to be spurious, but it produced much interest in this class of astronomical object.
