There are millions of asteroids in the solar system.

Asteroid Numbers

The vast number of asteroids makes it hard to give an exact count, but here's a breakdown based on the provided reference:

  • Numbered Minor Planets: As of May 2022, there were 614,690 numbered minor planets. These asteroids have well-determined orbits.

  • Un-numbered Asteroids: Approximately 500,000 un-numbered asteroids are known to exist. These require further observation to precisely determine their orbits and receive official numbered status.

In summary, while the precise number fluctuates as new discoveries are made and orbits are refined, we know of over a million asteroids in our solar system, with millions more estimated to exist.
