While in the descent between 10;000 and 8;500 feet Captain asked me; 'Did you see that?' I looked up in time to see an object going by the nose of the airplane; a few feet above us and opposite direction. The object passed us so quickly I did not have time to really get a look at it. The Captain asked if it was a drone; I said it might have been but I wasn't sure. The Captain notified ATC that we had a drone pass closely by us. The closure rate and size of the object meant that was not sufficient time to react if it had been necessary. Luckily the object missed us. The flight continued without further event.
EMB-145LR first officer reported a NMAC with a possible UAV during descent.
