246 Asporina is a sizeable Main belt asteroid. It is classified as one of the few R-type asteroids.

It was discovered by A. Borrelly on March 6, 1885 in Marseilles and was named after Asporina, a goddess worshipped in Asia Minor.

The spectrum of 246 Asporina reveals the strong presence of the mineral Olivine, a relatively rarity in the asteroid belt.[2]
