Felix Hormuth (b. 1975) is a German astronomer at the Max Planck Institute for Astronomy (MPIA) and a prolific discoverer of asteroids. During his stay at the Calar Alto Observatory in Spain, he has discovered a large number of asteroids, including a Jupiter trojan and two near-Earth objects, such as the 15-meter Amor asteroid 2009 DS36, using MPIA's 1.23-meter reflector telescope.
The Minor Planet Center ranks him 127th for a total of 75 credited discoveries of numbered asteroid during 2003–2009. Hormuth has named his discovered main-belt asteroids 241475 Martinagedeck and 342843 Davidbowie after actors and song-writer Martina Gedeck and David Bowie, respectively. He has also named 18610 Arthurdent after the character in Douglas Adams's radio play and book The Hitchhiker's Guide to the Galaxy.
Hormuth has worked with data obtained by the Infrared Space Observatory, was involved in the measurement campaign of the Very Large Telescope's GRAVITY-interferometer, and participated in the construction of optical instruments used at the NTT in La Silla, Chile. As of 2016, he is a project manager at MPIA, working for the Institute's hardware contribution to ESA's space-based Euclid mission, which will accurately measure the acceleration of the universe for the study of dark energy and dark matter.
