Hipparchus was the best astronomers of his time and was a Greek astronomer, geographer, and mathematician. He very accurately cataloged over 1,000 stars. Ptolemy was a great admirer of Hipparchus research and from what I've seen Ptolemy was often said to do what Hipparchus had done.
Latitude and longitude as a coordinate system were developed separately by Hipparchus and Ptolemy in the 2nd century BC. They both contributed significantly to the mapping and understanding of the Earth's surface, with Hipparchus focusing on latitude and Ptolemy introducing the concept of longitude.
Hipparchus is known for his work in astronomy, where he developed the first comprehensive star catalog and made important contributions to understanding the motion of celestial bodies. He also introduced the concept of epicycles to explain the complex movement of planets in the sky.
Hipparchus, the ancient Greek astronomer, believed that the Earth was the center of the universe, a view consistent with the geocentric model prevalent in his time. He posited that the Sun, Moon, planets, and stars revolved around the Earth in circular orbits. This geocentric perspective influenced astronomical thought for many centuries until the heliocentric model proposed by Copernicus emerged.
The Hipparchus's family is a mysterious family.
