59 Aurigae, often abbreviated as 59 Aur, is a star in the constellation Auriga. Its baseline apparent magnitude is 6.1, 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 {{Convert|483|ly|pc|abbr=off|lk=on}} away from the Sun.
In 1966, Ivan John Danziger and Robert John Dickens discovered that 59 Aurigae star is a variable star. 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 {{Convert|0.154412|days|hours|sigfig=2}}.{{citation | display-authors=1 | last1=Samus | first1=N.

The star's spectrum matches that of an F-type main-sequence star and it has a spectral type of F2V. It has 2.5 times the mass of the Sun and 5.7 times the Sun's radius. 59 Aurigae is thought to be around 700 million years old, and is radiating 64 times the Sun's luminosity from its photosphere an effective temperature of 6,808 K.
