497 Iva is a main-belt asteroid orbiting the Sun, not to be confused with 1627 Ivar. It was discovered by American astronomer R. S. Dugan on 4 November 1902, and was named for Iva Shores, the young daughter of the family where he was staying in Heidelberg.[1] This object is orbiting at a distance of Script error: No such module "val". with a period of Script error: No such module "convert". and an eccentricity of 0.3. The orbital plane is inclined at an angle of 4.8° to the plane of the ecliptic.[2]
This asteroid is classified as an M-type asteroid and is considered anhydrous[3] but oxidized.[4] Further analysis of the spectra suggests the "presence of either an olivine or high-Ca pyroxene phase in addition to orthopyroxene ± Type B clinopyroxene".[5] Analysis of light curves based on photometric data show a rotation period of Script error: No such module "val". with a brightness variation of Script error: No such module "val". in magnitude.[6]
