Difference between Astronomy and Satellite

Astronomy vs. Satellite

Astronomy (from ἀστρονομία) is a natural science that studies celestial objects and phenomena. In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit.

Asteroid

Asteroids are minor planets, especially those of the inner Solar System.
