2423 Ibarruri, provisional designation 1972 NC, is an eccentric, slow tumbling asteroid and Mars-crosser from the inner regions of the asteroid belt, about 7 kilometers in diameter. It was discovered by Russian–Ukrainian female astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj, on 14 July 1972.[4]
The spectral type of the asteroid is that of a rare A-type in the SMASS taxonomy, with its surface consisting of almost pure olivine, which gives the body a very reddish color. As of November 2015, only 17 minor planets of this type are known.[11] It orbits the Sun at a distance of 1.6–2.8 AU once every 3 years and 3 months (1,182 days). Its orbit shows a high eccentricity of 0.28 and an inclination of 4 degrees towards the plane of the ecliptic.
Ibarruri has a notably slow rotation period of 140 hours,[a][7] and seems to be in a non-principal axis rotation (NPAR), colloquially called as "tumbling".[12] As a spectroscopic A-type asteroid, it belongs to the larger group of bodies with a silicaceous composition. However, the Collaborative Asteroid Lightcurve Link classifies the asteroid into the carbonaceous group, despite the fact that is assumes a relatively high geometric albedo of 0.20,[3] which is rather typical for stony asteroids.
The minor planet was named after Rubén Ruiz Ibárruri (1920–1942), son of Spanish communist leader Dolores Ibárruri and a posthumous Hero of the Soviet Union. He enlisted in the Soviet army and died in the early stage of the Battle of Stalingrad in September 1942.[2] Naming citation was published on 8 February 1982 (M.P.C. 6649).[13]
