26794 Yukioniimi           Discovered 1977 Feb. 18 by H. Kosai and K. Hurukawa 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.
