Question:
The early Greeks are credited with many valid concepts in astronomy. Some of their theories were correct; some were later proven incorrect.

The Greeks also believed that an invisible sphere surrounding our planet contained the stars. This sphere rotated, explaining the apparent movement of constellations over time.
