List of minor planets

The following is a list of minor planets in ascending numerical order. Minor planets are small bodies in the Solar System: asteroids, distant objects, and dwarf planets, but not comets. As of 2022, the vast majority (97.3%) are asteroids from the asteroid belt. Their discoveries are certified by the Minor Planet Center, which assigns them numbers on behalf of the International Astronomical Union. Every year, the Center publishes thousands of newly numbered minor planets in its Minor Planet Circulars (see index). As of June 2025, the 811,552 numbered minor planets made up more than half of the 1,424,223 observed small Solar System bodies, of which the rest were unnumbered minor planets and comets.

The catalog's first object is 1 Ceres, discovered by Giuseppe Piazzi in 1801, while its best-known entry is Pluto, listed as 134340 Pluto. Both are among the 3.3% of numbered minor planets with names, mostly of people, places, and figures from mythology and fiction. (4596) 1981 QB and 788501 Gabi are currently the lowest-numbered unnamed and highest-numbered named minor planets, respectively.

There are more than a thousand minor-planet discoverers observing from a growing list of registered observatories. The most prolific discoverers are Spacewatch, LINEAR, MLS, NEAT and CSS. It is expected that the upcoming survey by the Vera C. Rubin Observatory will discover another 5 million minor planets during the next ten years—almost a tenfold increase from current numbers. While all main-belt asteroids with a diameter above 10 km (6.2 mi) have been discovered, there might be as many as 10 trillion 1 m (3.3 ft)-sized asteroids or larger out to the orbit of Jupiter; and more than a trillion minor planets in the Kuiper belt.
