3905 Doppler (1984 QO) is a main-belt binary asteroid discovered on August 28, 1984 by A. Mrkos at Klet and named for Christian Doppler.[1] A moon orbiting the asteroid every 2 days, 2 hours, and 48 minutes was found orbiting the asteroid in 2013. This is a fairly long orbital period for a moon of an asteroid of this size.[2]
