352 Gisela is an asteroid belonging to the Flora family[4] in the Main Belt that has an unusually high albedo. It was discovered by German astronomer Max Wolf on 12 January 1893 in Heidelberg, and named after his wife.[6] This minor planet is orbiting the Sun at a distance of 2.19 astronomical unit|AU with a period of 3.250 yr and an orbital eccentricity of 0.149. The orbital plane is inclined at an angle of 3.38° to the plane of the ecliptic.[2]
Photometric measurements of 352 Gisela during December 1999 were used to produce a light curve showing a sinodic rotation period of 7.49±0.01 h with a brightness variation of 0.32 in magnitude.[7] This period estimate was refined to 7.4796±0.0002 h in 2012.[4]
