(7526) Ohtsuka Main-belt Asteroid
Discovered on 2 January 1993 by T. Urata at Oohira.
Katsuhito Ohtsuka (b. 1959) is a curator of Tokyo Meteor Network and its meteorite collection. He studies the dynamics of small solar system bodies, specially (3200) Phaethon, 96P/Machholz and their complex members. A dynamical relationship between Phaethon and (155140) 2005 UD was discovered by him in 2005.Naming citation (MPC batch dated 2014-07-12), IAU / Minor Planet Center, via NASA/JPL
