It has the variable star designation V637 Monocerotis, while 19 Monocerotis is the Flamsteed designation. This object is visible to the naked eye as a faint, blue-white hued star with a baseline apparent visual magnitude of 5.00. It is receding from the Earth with a heliocentric radial velocity of +25 km/s. thumb|left|A light curve for V637 Monocerotis, plotted from TESS data This massive, B-type main-sequence star has a stellar classification of B1 V. It is a Beta Cephei variable, ranging from 5.01 to 4.96 magnitude with a period of 0.19 days.2009yCat....102025S VizieR Online Data Catalog: General Catalogue of Variable Stars (Samus+ 2007-2013) VizieR On-line Data Catalog: B/GCVS.

V. 2009 Closer examination shows there are three frequencies present, consisting of 5.22994, 0.17017, and 4.88956 cycles per day. At one point it was thought to be a marginal Be star, but this was not confirmed. The star is spinning rapidly with a projected rotational velocity of 274 km/s. It has 12.3 times the mass of the Sun and is radiating 4,817 times the Sun's luminosity from its photosphere at an effective temperature of 25,400 K. References MAST: Barbara A.
