(10260) Stellaseitz Main-belt Asteroid
Discovered on 4 October 1972 by L. Kohoutek at Bergedorf.
Stella Seitz (1968–2025) was a German astronomer who studied strong- and weak-gravitational lensing at all spatial scales. After her Ph.D. at the Max-Planck-Institut für Astrophysik, she joined the staff at the Universitätssternwarte München, where she became the pillar of the student laboratory and a mentor to many successful young scientists.Naming citation (WGSBN Bull. 6, #10, 7), IAU / Minor Planet Center, via NASA/JPL
