Abstract

Although it is more complicated to search for near-Earth object (NEO) families than main belt asteroid families, since differential orbital evolution within a NEO family can cause current orbital elements to drastically differ from each other, we have found that Apollo asteroids 1566 Icarus and the newly discovered 2007 MK₆ are almost certainly related. Specifically, their orbital evolutions show a similar profile, time shifted by only ∼1000 yr, based on our time-lag theory. The dynamical relationship between Icarus and 2007 MK₆ along with a possible dust band, the Taurid-Perseid meteor swarm, implies the first detection of an asteroidal NEO family, namely, the "Icarus asteroid family."
