3103 Eger is an Apollo and Mars-crosser asteroid that was discovered in 1982, by Miklós Lovas. It was named after the city of Eger, Hungary. With an albedo of 0.64,[1] it is a highly reflective near-Earth asteroid.

It makes eight approaches to Earth less than 30 Gm (0.2 AU) in the 20th and 21st centuries. The last close approach was on 4 August 2011 at 22.9 Gm (0.15 AU).[1]

3103 Eger is the only asteroid besides 4 Vesta identified as the parent body for specific meteorites. 4 Vesta is the parent body for Howardite, Eucrite, and Diogenite meteorites, while 3103 Eger is the parent body for Aubrite meteorites. In this characteristic 3103 Eger is related spectroscopically to the 434 Hungaria type asteroids, which are a Hirayama-family of orbital types, and E-type asteroids which form a spectroscopical type.
