Best Answer

Astronomy is the study of the universe with particular reference to celestial bodies. The planets, the moons, the sun and other stars, galaxies, etc. all fall under astronomy. Astronomy is comparable to a physical geographic study of space. Not to be confused with astrophysics, the study of the physics or composition of celestial bodies.

Astronomy is the scientific study of celestial objects (such as planets, comets, stars, galaxies etc. that originate outside the Earth's atmosphere (such as cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and the motion of celestial objects, as well as the formation & development of our universe.
