SIMBAD data

59 Aurigae, often abbreviated as 59 Aur, is a star in the constellation Auriga. Its baseline apparent magnitude is 6.1, [3] meaning it can just barely be seen with the naked eye as a dim, yellow-white hued star. Based on parallax measurements, it is located about 483 light-years (148 parsecs ) away from the Sun. [2]

This object is a Delta Scuti variable, meaning it varies in luminosity due to pulsations on its surface, ranging in magnitude from 5.94 down to 6.14 with a period of 0.154412 days (3.7 h). [6] For that reason, it has been given the variable star designation OX Aurigae. The star's spectrum matches that of an F-type main-sequence star and it has a spectral type of F2V. [4] It has 2.5 [9] times the mass of the Sun and 5.7 [2] times the Sun's radius. 59 Aurigae is thought to be around 700 million years old, and is radiating 64 [2] times the Sun's luminosity from its photosphere an effective temperature of 6,808 K.
