    It was discovered by Johann Palisa on 14 February 1891 in Vienna.

    304 Olga was identified as one of three asteroids that were likely to be a parent body for chondrites along with 449 Hamburga and 335 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]
