Vibrant green spheroid object racing along the valley floor over suburban residential area.

Driving southbound on Hawes Rd through Queen Creek, AZ at night, I observed what appeared to be an oblate spheroid shaped object. As I crossed the Chandler Heights Rd intersection, the street lamps were non-existent. This dark road and sky made sighting this jump out at my attention in the upper right of my windshield, as it was moving very fast. The color was a vibrant emerald green color with an aura of yellow around it. I thought i might be fireworks, but then it arched downward for a brief moment (as if dropping altitude) then leveled out and accelerated very rapidly in a straight horizontal line from east to west across the valley floor. I estimate it was downrange from my car as close as 3-miles away at an altitude of 500 feet which is well below the height of the San Tan Mountains (3,104 FT). It was accelerating much faster than any light aircraft or helicopter that is common to see in this area. The weather was windy with lots down drafting wind currents from a lines of thunderstorms in the area. It was dusty and gusty to 40 kTS which obscured the moonlight, so this was really bad weather for a private pilot to fly in with a light aircraft from nearby Pegasus-Queen Creek Airpark. I was driving at the time with my phone plugged into my armrest on Apple Car Play, so I didn't have enough time to grab my phone for snaps.
