(13446) Almarkim is an asteroid of the outer main belt , which was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The Italian astronomer Vincenzo Zappalà defines in a publication from 1995 (et al.) That 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 , 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. The ageless (not osculating ) orbital elements of (13446) Almarkim are almost identical with those of two smaller (when one of the absolute brightness of 15.1 and 15.6 compared to 12.5 emanates) asteroid: (140724) 2001 UL 94 and (346188) 2007 XQ .
(13446) Almarkim is named after the American actor Al Markim named (* 1927), one in the Venusians in the 1950s science fiction - TV show Tom Corbett, Space Cadet played. The asteroid was named on July 15, 2011.
