59 Aurigae, often abbreviated as 59 Aur, is a star in the constellation Auriga. Its apparent magnitude is 6.1,[2] meaning it can just barely be seen with the naked eye. Based on parallax measurements made by the Hipparcos spacecraft, it is located about 490 light-years (151 parsecs) away.[1]

59 Aurigae is a Delta Scuti variable, meaning it varies in luminosity due to pulsations on its surface. 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.[3] It is thought to be around 600 to 800 million years old, and has an effective temperature of 6808 K.[6]
