(11755) Paczynski Main-belt Asteroid
Discovered on 24 September 1960 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T. at Palomar.
Polish-born astrophysicist Bohdan Paczyński (b. 1940), at Princeton University since 1982, is known for his theoretical work on γ-ray bursters—he was an early proponent of their being at cosmological distances—and for leading searches for gravitational lensing by low-mass stars and substellar objects.Naming citation (WGSBN Bull. 6, #8, 5), IAU / Minor Planet Center, via NASA/JPL
