Round object seen briefly in the sky over Orlando

I was sitting on a patio listening to music at night and just looking at the sky when a round object, the size of a small coin, appeared very high in the sky and momentarily started to move south at a very fast speed. Only took a second before the subject went over my roof and out of my view. My house is located in the direct path of inbound planes to orlando so I see airplanes all the time. This object was weird. It was round, light up and immediately started to move in a straight line, not like a meteor. The meteor trajectory would have been curved. Not sure what it was.
