Orbit and classification
Cassini is a non-
background population. It orbits the Sun in the central asteroid belt at a distance of 1.8–3.5 AU once every 4 years and 4 months (1,571 days). Its orbit has an eccentricity of 0.31 and an inclination of 15° with respect to the ecliptic.[1]
In December 1926, the asteroid was first identified as 1926 XH at
Heidelberg Observatory in Germany. The body's observation arc begins 7 years prior to its official discovery observation, with a precovery taken at La Silla Observatory in March 1992.[8]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10 – a compromise value between the brighter stony (0.20) and darker carbonaceous (0.057) asteroids of the 2.6 to 2.7 AU-region of the asteroid belt – and correspondingly, calculates a larger diameter of 11.05 kilometers, as the lower a body's albedo (reflectivity), the larger its diameter for a given absolute magnitude (brightness).[3]
