California (minor planet designation: 341 California) is an asteroid belonging to the Flora family in the Main Belt. It was discovered by Max Wolf on 25 September 1892 in Heidelberg, and is named for the U.S. state of California.[5] This object is orbiting the Sun at a distance of 2.20 AU with a period of 3.26 yr and an eccentricity (ovalness) of 0.19. The orbital plane is inclined at an angle of 5.7° to the plane of the ecliptic.[1]

The very slow rotation rate of this asteroid favors collecting photometric data for an extended period in order to measure the period. Data collected from June to December of 2016 was used to produce a light curve showing a rotation period of 317.88±0.06 h with a brightness variation of 0.9 in magnitude. It is tumbling with a period of 250±2 h.[6] It has an unusually high albedo.
