(9241) Rosfranklin is an asteroid of the main belt , which on 10 August 1997 by the Australian amateur astronomer John Broughton by its private Reedy Creek Observatory ( IAU code 428) in Queensland was discovered.
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.
(9241) Rosfranklin was named on January 25, 2005 after the British biochemist and specialist in X-ray structure analysis Rosalind Franklin (1920–1958), whose research contributed significantly to the elucidation of the double helix structure of DNA .
