(224693) Morganfreeman is an asteroid of the main outer belt , which was discovered by the Italian amateur astronomer Vincenzo Silvano Casulli on January 21, 2006 at the observatory in the district of Vallemare ( IAU code A55) in the municipality of Borbona in the province of Rieti .
The asteroid is in a 3-2-1 orbit resonance with Jupiter and Saturn .
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of (224693) Morganfreeman roughly correspond to the Eos family , a group of asteroids that typically have major semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap the 7: 3 resonance with Jupiter, as well as orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(224693) Morganfreeman was named on April 22, 2016 after the American actor , director and Oscar winner Morgan Freeman . The dedication also highlights astronomy documentaries hosted by Morgan Freeman.
