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

: Objects sharing an orbit with a planet (Trojans) or orbiting between the giant planets (Centaurs). 3. Scientific Significance

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 minor planet

The study of minor planets is essential for several reasons: FindPOTATOs: Minor Planet Observation Linking Software

Minor planets, primarily comprising asteroids and dwarf planets, represent the primordial remnants of the early solar system. Unlike the eight major planets, these bodies have not cleared their orbital neighborhoods, providing a "frozen" record of the chemical and physical conditions present during the solar system's formation roughly 4.6 billion years ago. This paper examines the classification, distribution, and scientific significance of minor planets, highlighting their role in understanding planetary evolution and the modern methodologies used for their discovery and analysis. 1. Introduction and Classification : They must have sufficient gravity to achieve

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).

: Bodies located beyond the orbit of Neptune, including Kuiper Belt objects. Unlike the eight major planets, these bodies have
