(48300) Kronk is an asteroid of the main belt , which on 11 June 2002 by the amateur astronomer Charles W. Juel and Paulo R. Holvorcem at the Observatory of Fountain Hills ( IAU code was discovered 678) in the State of Arizona.
The celestial body was named on January 7, 2004 after the American amateur astronomer Gary W. Kronk (* 1956), whose four-volume work Cometography was published between 1999 and 2008.
The asteroid belongs to the Eos family, a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and 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.
