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 482 light-years (148 parsecs) away from the Sun.[2]
In 1966, Ivan John Danziger and Robert John Dickens discovered that 59 Aurigae star is a variable star.[13] 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, in 1975, it was given the variable star designation OX Aurigae.[14] The star's spectrum matches that of an F-type main-sequence star and it has a spectral type of F2V.[4] It has 2.4 times the mass of the Sun[9] and 5.7 times the Sun's radius.[10] 59 Aurigae is thought to be around 530 million years old,[12] and is radiating 62 times the Sun's luminosity[2] from its photosphere an effective temperature of 6,848 K.[10]
