Input (grade 13): Given the rapid rotation, rare for objects so large, Varuna is thought to be an elongated spheroid (ratio of axis 2:3), with a mean density around 1 g\/cm3 (roughly the density of water).
Output (grade 12): Given the fast rotation, which is not common for objects so big, Varuna is thought to be a stretched spheroid, with a density around 1g\/cm Â (close to the density of water).
