Lightbody

Lightbody refers to the total energy emitted by an object, such as a star, galaxy, or celestial body, over a specific period. It is often expressed as luminosity, which measures brightness regardless of distance. In astronomy, understanding a body's lightbody helps scientists determine its size, temperature, composition, and energy processes. Essentially, it quantifies how much light and energy an object produces, providing insights into its physical state and lifecycle within the universe.
