When had a short
observation arc of 3 days, some orbit solutions suggested it could be a
near-Earth object[ that was discovered when it was near aphelion 7 AU from the Sun.][ As a result of the possible near-Earth orbit, the Sentry Risk Table listed a non-significant 1:1-billion chance of impacting Earth on 12 October 2059.]
