By the time of Ptolemy Greek astronomers had proposed adding circles on the circular orbits of the wandering stars (the planets, the moon and the sun) to explain their motion. These circles on circles are called epicycles.
How did ancient Greece contribute to astronomy?
In classical Greece, astronomy was a branch of mathematics; astronomers sought to create geometrical models that could imitate the appearances of celestial motions. This tradition began with the Pythagoreans, who placed astronomy among the four mathematical arts (along with arithmetic, geometry, and music).
Why is Greek astronomy important?
The ancient Greeks were some of the first people to study the sky and understand astronomy. They realized the Earth was a sphere, or a three-dimensional circular object, and tried to measure its size. They also created an idea of a geocentric solar system in which everything orbits around the Earth.
How were planets discovered before telescopes?
Until the development of the telescope in the early 17th Century, all astronomical observations were made with the naked eye. By using measuring instruments, astronomers recorded the positions of the planets against the background of stars.
What are Greek inventions?
Greeks have bestowed the world with many other inventions. According to some sources, the Greeks are responsible for the alarm clock, computer, shower, automatic doors, cartography, the odometer, the stadium, and the arch bridge.
What practical value did astronomy offer?
What practical value did astronomy offer to ancient civilizations? It helped them keep track of time and seasons, and it was used by some cultures for navigation.
What was Aristotle’s contribution to understanding the universe?
Aristotle, who lived from 384 to 322 BC, believed the Earth was round. He thought Earth was the center of the universe and that the Sun, Moon, planets, and all the fixed stars revolved around it. Aristotle’s ideas were widely accepted by the Greeks of his time.
How was astronomy developed?
The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.
Who named Planet Earth?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.
Who discovered Earth?
The exoplanet was identified by the Kepler space telescope, and its discovery was announced by NASA on 23 July 2015. The planet is about 1,400 light-years away from the Solar System.

What is the greatest contribution of ancient Greece to the modern world?
The Theater. If you’ve ever gone to a concert, play or movie, you’ve benefited from one of the ancient Greeks’ most obvious contributions to the modern world: the theater. The word “theater” is derived from the Greek word “theatron,” meaning the seating section of outdoor arenas where people watched plays.
What did the Greeks do for us?
