How did ancient astronomers explain their observations?
The Ptolemaic Model
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 people know about astronomy?
Early Observations:
Early people noticed constellations of stars in the sky that looked like animals and people, and made up stories about what they thought they saw.
In fact, the oldest records we have of astronomical observations are 30,000-year-old paintings found on the walls of caves..

The ancient Greeks thought the Earth was the centre of the Universe.
This idea is called the geocentric model which means Earth-centred.
This belief seemed to explain why stars look like they move around the Earth once a day.
It also explained why planets seem to move faster than stars in the night sky..

In fact, the oldest records we have of astronomical observations are 30,000-year-old paintings found on the walls of caves.
Ancient Egyptians were very interested in the night sky.
In particular, they were drawn to two bright stars that always could be seen circling the North Pole..
What was the theory of ancient astronomy?

These rotated and gave rise to the motion of the heavens around the fixed earth..

This 30 cm bronze disk depicts the Sun, a lunar crescent and stars (including the Pleiades star cluster)..
Which ancient civilization knew a lot about astronomy?
Considered the world's first-known astronomers, the ancient Babylonians were avid stargazers.
Some 6,000 years ago, they erected watch towers to scan the night sky, mapped the stars and visible planets and recorded their observations on clay tablets..
Who discovered the ancient astronomy?
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE.
From this cradle of civilisation in Mesopotamia – in the southern part of present-day Iraq – astronomers had built up knowledge of the celestial bodies and recorded their periodic motions..
Who was the greatest astronomer of ancient times?
Hipparchus was born in Nicaea, Bithynia, and probably died on the island of Rhodes, Greece.
He is known to have been a working astronomer between 162 and 127 BC.
