Its apparent magnitude is 4.5 and it is approximately 780 pc ly away. 13 Mon lies within the Monoceros OB1 Association, halfway between the Rosette Nebula and NGC 2264, at a distance of about 780 parsecs. It is surrounded by a small reflection nebula listed as Van den Bergh 81 (VdB 81).1966AJ.....71..990V A study of reflection nebulae Astronomical Journal 71 990 Van Den Bergh S. 1966 10.1086/109995 13 Monocerotis has been used as a standard star for the A0 Ib spectral class.1950ApJ...112..362M Revised Standards for Supergiants on the System of the Yerkes Spectral Atlas Astrophysical Journal 112 362 Morgan W.
