[2] 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).
[3][9] In January 2014, two rotational lightcurves of Iguassú were obtained at the Palomar Transient Factory in California.
They gave a rotation period of 9.14 and 9.23 hours, respectively, both with a brightness change of 0.15 in magnitude (U=2/2).
[2] As a curiosity, the spelling of the minor planet's name (Iguassú) neither concurs with the Spanish "Iguazú" nor with the Portuguese "Iguaçu".
It is rather similar to "Yguasu", used in the native Guarani language, from which the waterfall's name originates.
