The Wandering Planets |
The Planets of our Solar SystemThe early Greeks described the planets as 'the wanderers' because in contrast with the stars that remained fixed relative to each other, the planets moved across the starfields at different speeds and not only that, but sometimes they seemed to stop and reverse their direction of movement. For many centuries different theories tried to explain these movements but they were all bound to fail because they still placed the Earth as the center of the solar system. Planets look like stars in the night sky, however there is one major difference; stars emit light & planets reflect light from the Sun.
