Minor Planet Instant

Minor planets are found in diverse regions of the solar system, reflecting various evolutionary paths:

: Located between the orbits of Mars and Jupiter, this region contains the highest concentration of rocky asteroids.

: Bodies located beyond the orbit of Neptune, including Kuiper Belt objects. minor planet

The term "minor planet" is an astronomical classification encompassing all small solar system bodies that are not comets. As of early 2026, over 1.5 million minor planets have been identified. These bodies are distinguished from major planets based on three criteria established by the International Astronomical Union (IAU) : : They must orbit a star (the Sun).

: Objects sharing an orbit with a planet (Trojans) or orbiting between the giant planets (Centaurs). 3. Scientific Significance Minor planets are found in diverse regions of

: They must have sufficient gravity to achieve a nearly spherical shape.

: Crucially, minor planets have not cleared their orbital path of other debris. As of early 2026, over 1

A sub-category, , includes larger minor planets like Pluto , Ceres, Eris, Haumea, and Makemake, which meet the shape criteria but fail to clear their orbits. 2. Distribution and Populations
