Welcome to the Hellenic Astronomical Society

Astronomy, the "law of the stars" or "αστρονομία" in greek, is one of the oldest sciences. Many of the developments in early astronomy have their origin in the ancient greek world. These include the first estimates on the size of the Earth, the distances to the Moon and the Sun, and the explanation of the eclipses. The motions of other objects in our solar system were also understood and it was suggested that the Milky Way consists of numerous stars like our Sun. More than two millennia have passed and the tradition in astronomy is still alive in Greece...
