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. The orbital plane is inclined at an angle of 4.8° to the plane of the ecliptic.[2]
