Italian scientists Ernesto Guido and Giovanni Sostero told RIA Novosti that it had an orbital period of almost exactly one year and might be a spent rocket booster. However, it was determined that it is a near-Earth asteroid.
Based an estimated diameter of 10–15 m (33–49 ft), if 2010 AL30 had entered the Earth's atmosphere, it would have created an air burst equivalent to between 50 kT and 100 kT (kilotons of TNT). The Nagasaki "Fat Man" atom bomb had a yield between 13–18 kT.
