(8260) Momcheva Main-belt Asteroid
Discovered on 23 September 1984 by Bulgarian National Observatory at Smolyan.
Bulgarian astronomer Ivelina Momcheva (b. 1980) is known for her research on gravitational lensing and galaxy clusters. While she has already glimpsed the 3D structure of the distant universe through her research, she still hopes to achieve her life goal of glimpsing an antlered moose in the wild.Naming citation (MPC batch dated 2016-11-14), IAU / Minor Planet Center, via NASA/JPL
