Short description: Main-belt asteroid

Russia (minor planet designation: 232 Russia) is a large Main belt asteroid. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material. It was discovered by Johann Palisa on 31 January 1883 in Vienna, who named it after the country of Russia .

Photometric observations of this asteroid collected during 2007 show a rotation period of 21.8 ± 0.2 hours with a brightness variation of 0.2 ± 0.02 magnitude.^[2] A follow-up study during 2014 discovered that the rotation period varied depending on the phase angle of observation. The measured rotation varied from 22.016 ± 0.004 hours at a phase angle of 21.5 degrees to 17.0, to 21.904 ± 0.002 hours at phase angles between 5.2 degrees and 9.6 degrees. The reason for this variation has to do with the shape of the asteroid.^[3]
