Green orb that seemed to fall in slow motion.Driving home with my husband from the store, crossing train tracks on cherry st. I saw a green orb about the size of a volley ball appear mid sky for about 5 seconds. It seemed to fall North in slow motion in a diaginal angle for about another 5 seconds and then diappeared. My husband works for the FAA, but did not see it due to driving and it was to his left. Eyes were on the road.
