(26794) Yukioniimi Main-belt Asteroid
Discovered on 18 February 1977 by Kosai, H., Hurukawa, K. at Kiso.
Niimi Yukio (b. 1937) analyzed the relation between the coordinate system of the Fourth Fundamental Catalog (FK4) and that of the Planetary Dynamical Theory (DE200, VSOP82) with modern observations of planets. His result obtained from Mars observations was used by Fricke to determine the correction to the FK4 Equinox.Naming citation (MPC batch dated 2018-05-29), IAU / Minor Planet Center, via NASA/JPL
