}}{{Starbox end}}Omega Aurigae, Latinized from ω Aurigae, is the Bayer designation for a double star[21] in the northern constellation of Auriga. Its apparent magnitude is 4.95,[3] which is bright enough to be seen with the naked eye. The distance to this system, as determined using parallax measurements, is approximately {{Convert|159|ly|pc|abbr=off|lk=on}}.This is an A-type main sequence star with a stellar classification of A1 V.[5] It has 2.3[4] times the mass of the Sun and is radiating 27[12] times the Sun's luminosity from its photosphere at an effective temperature of 9,230 K.[5] The object displays an infrared excess, suggesting an orbiting debris disk with a temperature of 20 K at a mean radius of {{Val|932.40|ul=AU}} from the host star.[28] It has a magnitude 8.18 companion at an angular separation of 4.99 arcseconds.[21] The system is an X-ray source with a luminosity of {{Val|16.57e29|u=ergs s−1}}.[30] References1. ^1 2 3 {{citation | title=XHIP: An extended hipparcos compilation | last1=Anderson | first1=E. | last2=Francis | first2=Ch. | journal=Astronomy Letters | volume=38 | issue=5 | pages=331 | year=2012 | bibcode=2012AstL...38..331A | doi=10.1134/S1063773712050015 | arxiv=1108.4971 | postscript=. }}
