(20029) Dorner Main-belt Asteroid
Discovered on 2 March 1992 by UESAC at La Silla.
Rudolph Dorner (1948–2022) was a German-Canadian amateur astronomer, an electrician, machinist, investor and telescope collector. As a member of the RASC Kitchener-Waterloo Centre, he provided active, generous assistance to observers and instrument makers to extend themselves in their craft. The RASC's Dorner Telescope Museum is due to his inspiration.Naming citation (WGSBN Bull. 3, #15, 8), IAU / Minor Planet Center, via NASA/JPL
