304 Olga is a largeMain beltasteroid. It is classified as aC-type asteroid and is probably composed ofcarbonaceous material.
It was discovered byJohann Palisa on 14 February 1891 inVienna.
304 Olga was identified as one of three asteroids that were likely to be a parent body forchondrites along with449 Hamburga and335 Roberta.[4] All three asteroids were known to have low-albedo (not reflect as much light) and be close to "meteorite producing resonances".[4] Chrondrites are the most common type of meteor found on Earth, accounting for over 80% of all meteors.[5] They are named for the tiny spherical silicate particles that are found inside them (those particles are called chondrules).[5]
