摘要: The orbit of the Chelyabinsk object is calculated, applying least-squares method directly to astrometric positions. dynamical evolution this in past studied by integrating equations motion for particles with orbits from confidence region. It found that majority clones reach near-Sun state. 67 percent these objects have collisions Sun 15 Myr our numerical simulations. distribution minimum solar distances shows most probable time encounters lies interval -0.8 -2 Myr. This consistent estimate a cosmic ray exposure age 1.2 (Popova et al 2013). A parent body should experience strong tidal and thermal effects at time. possible association 86039 (1999 NC43) 2008 DJ discussed.
