This is consistent with the estimate of a cosmic ray exposure age (Popova et al., 2013). Dynamical features of the flux of Chelyabinsk-type bodies have been studied by numerical integrations, assuming their origin near the Sun about 1 Myr ago. The most frequent fate of these bodies is solar collision. But about a quarter of all the original objects survive until the present epoch. The majority of the surviving bodies are typical near-Earth objects. The rate of their encounters with the Earth is almost constant for the last 0.5 Myr. About a third of the Chelyabinsk-type objects approach the Earth from the Sun direction.<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>V.V.
