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.

[3] This object is orbiting at a distance of 2.85 AU with a period of 4.82 yr and an eccentricity of 0.3.

[5] Further analysis of the spectra suggests the "presence of either an olivine or high-Ca pyroxene phase in addition to orthopyroxene ± Type B clinopyroxene".

[6] Analysis of light curves based on photometric data show a rotation period of 4.621±0.001 h with a brightness variation of 0.34±0.02 in magnitude.
