(241475) Martini deck is an asteroid located in the outer main belt . It was discovered by the German astronomer Felix Hormuth on January 25, 2009 at the Spanish Calar Alto Observatory ( IAU code 493).
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of (241475) Martini deck roughly correspond to the Eos family , a group of asteroids, which typically have major semiaxes of 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.
(241475) Martinagedeck was named after the German actress Martina Gedeck (* 1961) on July 2, 2015 at the suggestion of Felix Hormuth . Two films from 2006 in which she played were particularly emphasized in the naming text: “ The Lives of Others ” and “ The Good Shepherd ”.
