NGC 7023 is a reflection nebula, meaning it reflects the light of some nearby stars; probably the main star responsible for its illumination is precisely the star cataloged as HD 200775, which would be surrounded by the nebula, together with other less bright stars born from its dust and which form the open cluster. The nebula is probably about 1400 light-years away from us and measures about 6 al. It is likely part of the vast Cepheus Molecular Nebula Complex.
