Astronomical objects are natural entities in the universe that can be observed from Earth or through telescopes. These include a wide variety of items such as stars, planets, moons, comets, and galaxies. Each of these objects has unique characteristics, such as size, composition, and behavior, contributing to our understanding of the cosmos.
Many astronomical objects are part of larger systems, like solar systems or galaxies. For example, our own Solar System consists of the Sun, eight planets, and their moons. Studying these objects helps scientists learn about the formation and evolution of the universe, as well as the potential for life beyond Earth.
