Ross 248 is a red dwarf star approximately 3.2 pc or 10.33 light years from Earth's Solar System. This is a flare star that occasionally increases in luminosity. Its nearest neighbour is the Gl 15 Star System (GX and GQ Andromedae), a mere 0.47 pc or 1.54 ly away.

Radial velocity is the velocity of an object in the direction of the line of sight. ... kilometre per second is an SI derived unit of both speed (scalar) and velocity (vector), signified by the symbol km/s or km s-1. ... The proper motion of a star is the motion of the position of the star in the sky (the change in direction in which we see it, as opposed to the radial velocity) after eliminating the improper motions of the stars, which affect their measured coordinates but are not real...
