Its retrograde nearly ecliptic orbit (i ≈ 175°) combined with a relatively small perihelion distance (q ≈ 1.36 AU) effectively directs the interloper "against traffic" through the densely populated regions of the inner Solar System. This significantly increases the probability of close encounters and potential interaction (inclu...
