(17700) Oleksiygolubov Main-belt Asteroid
Discovered on 7 April 1997 by E. W. Elst at La Silla.
Oleksiy (Alex) Golubov (b. 1985) has changed our understanding of the YORP effect through his theory of Tangential YORP, which helps explain the measured spin evolution of asteroids. His current work has identified several new equilibrium states that can exist for binaries, leading to important new predictions for how these bodies dynamically evolve.Naming citation (MPC batch dated 2019-12-12), IAU / Minor Planet Center, via NASA/JPL
