The C / 2010 U3 (Boattini) is the sixteenth comet discovered by Italian Andrea Boattini.

It is a comet with unusual characteristics, both for the diameter of its nucleus, of the order of 100 km for both the distance perihelion, halfway between the orbits of Saturn and Jupiter, both for the time of discovery, almost nine years before the perihelion passage. Its orbital elements are still relatively uncertain since it will be necessary to specify them follow the comet along a majority observational arc, is already known, however, that it is a non-periodic comet, and to observe it will be necessary to use at least of medium size telescopes
