1684 Iguassú, provisional designation 1951 QE, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 30.5 kilometers in diameter. It was discovered on 23 August 1951, by Argentine astronomer Miguel Itzigsohn at the La Plata Astronomical Observatory, located in the city of La Plata, Argentina.[10] It was named after the Iguazu Falls in South America.[2]
Orbit and classification
The asteroid orbits the Sun in the outer main-belt at a distance of 2.7–3.5 AU once every 5 years and 5 months (1,992 days). Its orbit has an eccentricity of 0.13 and an inclination of 4° with respect to the ecliptic.[1]
