225 Henrietta
225 Henrietta is a very large outer main-belt asteroid. It was discovered by Johann Palisa on April 19, 1882, in Vienna and named after Henrietta, wife of astronomer Pierre J. C. Janssen. This is classified as a C-type asteroid and is probably composed of privitive carbonaceous material. It has very dark surface, with an albedo of 0.040. Photometric measurements made from the Oakley Southern Sky Observatory during 2012 gave a light curve with a period of 7.352 ± 0.003 hours and a variation in brightness of 0.18 ± 0.02 in magnitude. This is consistent with a synodic rotation period of 7.356 ± 0.001 hours determined in 2000.
