497 Iva

Iva (minor planet designation: 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. This object is orbiting at a distance of $2.85 AU$ with a period of 1758.8 days and an eccentricity of 0.3. The orbital plane is inclined at an angle of 4.8° to the plane of the ecliptic.

This asteroid is classified as an M-type asteroid and is considered anhydrous but oxidized. Further analysis of the spectra suggests the "presence of either an olivine or high-Ca pyroxene phase in addition to orthopyroxene ± Type B clinopyroxene". Analysis of light curves based on photometric data show a rotation period of $4.621 hours$ with a brightness variation of $0.34$ in magnitude.
