Binary stars offer the opportunity to directly measure the mass of each component, but in the case the orbital inclination is very low and the masses cannot be accurately determined. The stars are orbiting extremely close together, separated only by about the diameters of the stars themselves. They complete one orbit in just over three days.[3] Although HD 48099 only has a moderate space velocity of 37.7 km/s, it has produced a bow shock 2.26 parsecs from the star itself.[5] References1. ^1 2 3 4 {{cite journal|bibcode=2007A&A...474..653V|title=Validation of the new Hipparcos reduction|journal=Astronomy and Astrophysics|volume=474|issue=2|pages=653|author1=Van Leeuwen|first1=F.|year=2007|doi=10.1051/0004-6361:20078357|arxiv = 0708.1752 }} {{Stars of Monoceros}}2. ^1 2 {{cite journal|bibcode=2002yCat.2237....0D|title=VizieR Online Data Catalog: Catalogue of Stellar Photometry in Johnson's 11-color system|journal=CDS/ADC Collection of Electronic Catalogues|volume=2237|author1=Ducati|first1=J.
