## TL;DR

This paper explores the 19th-century astronomical studies of asteroids by Christian Ludwig Gerling and his students, highlighting their pioneering observational and theoretical contributions to asteroid astronomy.

## Contribution

It presents a historical analysis of Gerling's and his students' pioneering asteroid observations and orbit calculations in the 19th century, emphasizing their role in early asteroid astronomy.

## Key findings

- First astrometric measurements of minor bodies in Hesse.
- Gerling's data contributed to asteroid ephemeris calculations.
- Students analyzed asteroid orbit perturbations.

## Abstract

One of the mayor topics in astronomy at the beginning of the 19th century was the interpretation of the observations of the first asteroids. In 1810 Christian Ludwig Gerling at the age of twenty two came to G\"ottingen University to continue his academic studies. Supervised by Carl Friedrich Gau{\ss} at the observatory he was engaged in studies of theoretical and practical astronomy. Starting in 1812 Gerling accepted the responsibility for collecting observational data of the asteroid Vesta from the European observatories and for calculating the ephemeris of this new minor planet. In 1817 Gerling was appointed professor at Marburg University. One of his early astronomical projects in Marburg was his contribution to the Berliner Akademische Sternkarten. After completion of his observatory in 1841 Gerling's students started observing and theoretically analysing the orbits of the continuously newly discovered asteroids including the perturbation of the larger solar system bodies. The observations at Gerling's observatory are the first astrometric measurements of solar systems minor bodies of Hesse.
