An astronomical object is any physical entity in the universe that can be observed and studied. This includes a wide range of items such as stars, planets, moons, asteroids, comets, and galaxies. Each of these objects has unique characteristics, such as size, composition, and behavior, which scientists analyze to understand the cosmos better. Astronomical objects can be found in various locations, from our own solar system, which includes the Earth and Mars, to distant galaxies like the Milky Way and Andromeda. Observing these objects helps astronomers learn about the formation and evolution of the universe.
