As an expert in the field of astronomy and history of science, I can provide you with a detailed account of the development of the world's first star catalog.
The history of star catalogs dates back to ancient civilizations, where the systematic recording of celestial bodies was an essential part of astronomical observations. The first known comprehensive star catalog was created by Hipparchus, a Greek astronomer, and mathematician who lived around 190–120 BCE. Hipparchus is often referred to as the father of trigonometry and is renowned for his significant contributions to astronomy.
His star catalog, completed around 129 BCE, was a groundbreaking work that listed the celestial longitudes and latitudes of approximately 850 stars. This catalog was not only a compilation of star positions but also a tool that allowed for the study of celestial movements and the determination of precession—the gradual shift in the position of equinoxes and solstices due to the Earth's axial wobble.
Hipparchus' work laid the foundation for future astronomical endeavors. It was later expanded and improved upon by Ptolemy, another prominent astronomer and mathematician from Alexandria. Ptolemy's work, known as the Almagest, was completed around 140 CE. The Almagest is a 13-volume treatise that not only included an updated and more detailed star catalog but also presented a comprehensive model of the universe, which became the dominant astronomical theory for over a thousand years.
The Almagest's star catalog contained detailed information on over a thousand stars, including their brightness, position, and the constellations they were associated with. Ptolemy's systematization of this information was a monumental achievement that greatly influenced the field of astronomy for centuries to come.
It is worth noting that while the Bonn survey, initiated in 1886, extended the cataloging of stars far beyond the numbers recorded by Hipparchus and Ptolemy, it was built upon the foundational work of these early astronomers. The Bonn survey and subsequent efforts have significantly contributed to our modern understanding of the cosmos, but the pioneering work of Hipparchus and Ptolemy remains a cornerstone of astronomical history.
In summary, the world's first star catalog was developed by Hipparchus, and it was later expanded by Ptolemy in his Almagest. Their work has had a profound and lasting impact on the field of astronomy.

The Bonn survey was extended to ?23-- in 1886,-- Hipparchus completed the first known catalog in 129 bce, giving the celestial longitudes and latitudes of about 850 stars. This work was enlarged and improved by Ptolemy, the Alexandrian astronomer and mathematician, in his Almagest (c. 140 ce).
