VdB 151 is a reflection nebula visible in the constellation of Lacerta. It is located in the southern part of the constellation and surrounds a fourth magnitude star visible to the north of star 1 Lacertae. The central star of the nebula is HD 211073, an orange giant with spectral class K3III forming part of a binary star system. Its parallax indicates a distance of about 173 parsec (564 light years). The surrounding environment is particularly rich in partially ionized gases and illuminated dust, given the presence of the association Lacerta OB1.
