Greek Astronomy for Kids - the Earth. Who figured out that the earth was round and that it went around the sun?

Greek Astronomy: The Earth

earth

Early Greeks thought of the Earth as the goddess Gaia, the mother of everything. By the Classical period, however, at least educated Greeks like Thales knew that the earth was a round ball, and by the Hellenistic period Greek scientists like Eratosthenes were able to use astronomy and geometry to measure the circumference of the earth (the distance around it). Aristarchus, finally, showed that the earth went around the sun.
