The Origins of Greek Astronomy

The term astronomy came into English from ultimate Greek origins in the 13th century. Like many of those words it gets to us from Greek to Latin to French and then to English. The root of this word is astro which comes from the Greek word astor which meant star. And speaking of Greek astronomy, during the time of the ancient Greeks, the star Sirius was the brightest star in the night sky. It rose just before or at the same time as the sun in the summer months. This resulted in many English words like astronomy, astrology, astrophysics, and astro not just the name of few.
