Bright planetlike object moved NW to SE until it changed direction and moved South to the horizon.I was on my deck and noticed what looked like a very bright planet, (round and not twinkling) moving quickly compared to a plane or satellite from Northeast toward Southeast. Then nearly directly over my head it turned south and continued South to the horizon until I could no longer see it. Never saw any blinking lights, and it moved too fast to be a plane or a sattellite. Never changed shape, just got smaller as it approach the southern horizon.
