It appears to be a main sequence red dwarf star of spectral and luminosity type M4.5 V. Because of its small mass and great distance from the primary (Star A), Upsilon Andromedae B appears to have a negligible effect on the radial velocity measurements used to determine that Star A has at least three large planets (Lowrance et al, 2002).
Professional surveyors (whether property surveyors or galactic surveyors) can then use basic trigonometry to compute the distance to the object if they have the distance between the two measurements and the parallax.
On the whole, recent VLBI parallax measurements have shown that photometric distance estimates, when available, tend to be considerably more accurate than kinematic estimates.

Previously classed as spectral type M4.5 e (with emission lines), the object was observed to be four times brighter than would be expected for a dim red dwarf of that type based on a revised parallax measurement of its distance from the Solar System (Ken Croswell, Science@Now, September 6, 2011).
The new distance measurement also enabled the astronomers to determine that EGS - zs8 - 1 was still forming stars very rapidly, about 80 times faster than our Milky Way galaxy today (which has a star formation rate of one star per year).
