(175281) Kolonics is an asteroid of the main outer belt , which was discovered on May 28, 2005 by the Hungarian amateur astronomer Krisztián Sárneczky at the Piszkéstető Observatory ( IAU code 561) in the northern Hungarian Mátra Mountains on behalf of the Budapest Konkoly Observatory .
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. The timeless (non- osculating ) orbital elements of (175281) Kolonics are almost identical to those of the larger one, assuming the absolute brightness of 13.7 compared to 15.8, asteroids (55937) 1998 FN 105 .
(175281) Kolonics was named on September 23, 2010 at the suggestion of the astronomer Péter Székely after the Hungarian canoeist and two-time Olympic champion György Kolonics (1972-2008).
