Theoretical astronomy definition
Webb4 jan. 2024 · Astronomical models are representations of planets showing them in their orbits around the celestial body at the center of the solar system. These models were made by diligently tracking planetary and stellar orbits observed through telescopes. Observational astronomy is a division of the astronomical science that is concerned with recording and interpreting data, in contrast with theoretical astrophysics, which is mainly concerned with finding out the measurable implications of physical models. It is the practice of observing celestial objects by using telescopes and other astronomical apparatus.
