VdB 25 is a small reflection nebula visible in the constellation Taurus. It is located along the line joining the star υ Tau to Atlas, the easternmost part of the Pleiades. It is an extremely tenuous and not easily detectable gaseous filament, which extends north of the star HD 26514, a yellow giant of spectral class G5III with an apparent magnitude 7.44. HD 26514 is also a binary star, in which the smaller companion has a magnitude 9,72. The two components of this binary system have an angle separation just one arcsecond. The distance to the star and its associated nebula is estimated to be 526 light-years.
