495 Eulalia is a minor planet, specifically an asteroid orbiting in the asteroid belt. Eulalia is very near the 3:1 Jupiter orbital resonance. It is a member of the Eulalia family of asteroids, which is part of the Nysa–Polana complex of asteroids.
It is possible that the disruption of Eulalia's parent body resulted in a mass bombardment of the Earth and Moon 800 million years ago, forming the Copernicus crater on the Moon and involving about 50 times the amount of material of the Chicxulub impact on Earth at the beginning of the Cryogenian geological period.Terada, K., Morota, T. & Kato, M.
