A common origin for dynamically associated near-Earth asteroid pairs

We present analysis that supports the existence of two genetically related asteroid pairs in near-Earth space. This work suggests that these systems formed via radiative spin-up and fission, and/or dissociation of a binary asteroid. Backwards orbital integrations suggest a separation age of <10 kyr for one of these pairs, making it one of the youngest multiple asteroid systems known to date. As the NEO catalog grows with current and future discovery surveys, the known population of NEO pairs will also increase.
