Types of Astronomical Objects - TOML

Astronomical objects refer to naturally occurring physical entities, associations, or structures that exist within the observable universe. Various objects exist at different scales and with different properties, including stars, planets, satellites, asteroids, comets, nebulae, galaxies, and black holes, which are systematically classified by organizations such as NASA and ESA. These classifications are based on the physical properties, evolutionary stages, and cosmic positioning of celestial bodies.
