Astronomy is an unphysical science which studies heavenly objects and celestial phenomena. It makes use of astronomy, mathematics, and science in order to describe their formation and movement. Common objects of interest are celestial satellites, planets, stars, comets, and other celestial bodies. The study of the stars and the moon is known as astronomy.

Astronomy combines mathematics and physical science to study celestial bodies such as the stars, planets, and the moon. Astronomy combines mathematics with astronomy in order to produce a physical description of an astronomical object. For example, if an astronomical object is being observed through a telescope, its orbit can be described by a mathematical model in a way that is both stable and consistent with scientific knowledge about that particular system. Similarly, if the moon is imaged through a telescope, its orbit can also be described in a model that is both well-suited to the orbit and consistent with general knowledge about the moon.

Astronomy is the study of celestial objects to understand their orbit, composition, structure, and environment. The study of celestial objects originated with Greek mythology. In modern times, astronomy is used to study all the various objects in the universe. Astronomy is the application of astronomy to the natural world around us. Its main components are science (the study of reality), mathematics (the study of form), and art (the design of an observatory and its operations). Astronomy teaches us about the universe and the laws that govern it.
