Hipparchus was best known for many things. One of them, he invented trigonometry.
Hipparchus is best known for his development of trigonometry and his introduction of a systematic way to measure the positions of celestial bodies. He created the first known star catalog, which included the brightness and positions of over 850 stars. Additionally, he is credited with the discovery of the precession of the equinoxes, demonstrating that the orientation of the Earth's axis shifts over time. His work laid the foundations for future astronomical studies.
The first catalog of stars is credited to the Greek astronomer Hipparchus, who compiled his observations in the 2nd century BCE. Hipparchus cataloged around 850 stars and classified them based on their brightness.
The astrolabe was invented by the ancient Greeks, specifically by Hipparchus in the 2nd century BCE.
Hipparchus' discoveries in astronomy were important because he developed the first systematic model of the motion of the Sun and Moon, and compiled one of the earliest known star catalogs with over 850 stars. His work laid the foundation for future astronomers and greatly contributed to the understanding of celestial movements.
It is first mentionned in writing by Ptolemy in the second century AD, however some believe that it was actually named by Hipparchus approx 120BC. It is unlikely that whoever discovered it when will ever be known
Hipparchus was best known for star catalog..
Not a lot is known about Hipparchus, including where and how he was educated, and of he went to school.
There is limited information about the personal life of Hipparchus, an ancient Greek astronomer. It is believed that he had a daughter, but not much is known about his family beyond that. Hipparchus is primarily known for his significant contributions to the field of astronomy.
Hipparchus is best known for his discovery of the precessional movement of the equinoxes. The alterations of the measured positions of the stars resulting from the movement of the points of intersection of the ecliptic and of the celestial equator.

Hipparchus has written: 'The geographical fragments of Hipparchus' -- subject(s): Ancient Geography
The Hipparchus's family is a mysterious family.
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.
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.
