490 Veritas is a carbonaceous Veritasian asteroid, which may have been involved in one of the more massive asteroid-asteroid collisions of the past 100 million years.
With an diameter of more than 100 kilometers, Veritas is the largest member and namesake of the Veritas family, a mid-sized asteroid family of carbonaceous asteroids in the outer main-belt, that formed recently approximately 8.5±0.5 million years ago.
Veritas and Undina would have been the largest fragments of that collision which caused a "late Miocene dust shower".
Substantiating Nesvorný's estimate, Kenneth Farley et al. found evidence in sea-floor sediments of a fourfold increase in the amount of cosmic dust reaching Earth's surface, which began 8.2 million years ago and tapered off over the next million and a half years.
Today continuing collisions among Veritas-family asteroids are estimated to send five thousand tons of cosmic dust to Earth each year, 15% of the total.
