Celestial Object Types - INI
Celestial object types are classifications of natural bodies in space based on their properties and characteristics. Stars, planets, dwarf planets, satellites, comets, asteroids, and meteors are the major classifications, each with distinct physical properties and formation processes. According to definitions by the International Astronomical Union (IAU), solar system objects are broadly categorized into three groups: planets, dwarf planets, and small solar system bodies. These classifications serve as foundational knowledge for astronomical research and space exploration.
