SIMBAD	data

60 Aurigae is a binary star[3] system in the northern constellation of Auriga. The pair have a combined apparent visual magnitude of 6.319[2] and, based upon parallax measurements, they are approximately 210 light-years (64 parsecs) distant from the Earth.[1]

The combined spectrum of the pair match a stellar classification of F5 V.[4] The primary component may be an A-type star with an apparent magnitude of 6.47,[3] while the fainter, 8.96 magnitude secondary is possibly a G-type star. The pair orbit each other with a period of 271.1 years at an angular separation of 0.793 arcseconds.[6]

Nomenclature

60 Aurigae is the Flamsteed designation of this star, also catalogued as HR 2541 and HD 50037. The designation 60 Aurigae has sometimes been identified with Psi⁸ Aurigae however Simbad lists Psi⁸ Aurigae as 61 Aurigae.[7]

gollark: They probably wrote them down.

gollark: You could also just use software raid or whatever.

gollark: It seems to just dump environment variables. I'm not entirely sure why you'd want a PHP equivalent.
