Saw a bluish green gumdrop shaped object flying probably around 1000 feet. Flew off at an incredible speed west towards the horizon

The light was obviously visible to me and my passenger and was immediately abnormal looking. The object was a solid blue ish green light not flashing or pulsing. The object moved so fast towards the horizon it almost appeared to fly into the ground. Flow flying air planes and helicopters are very common in this areas and I see them on a nearly daily basis but this was very clearly different to me and my passenger. The object moved so fast it was hard to get a clear image of what it was but it appeared to be a gumdrop shape. No noise was heard and the light was not bright enough to illuminate the ground but was a stark contrast to the black starless night sky of Atlanta. The object seemed very large. I was traveling west approximately 70mph and the object flew past at a speed seemingly hundreds of miles per hour. Neither of us have ever seen something like this but this was so completely odd I must report. There would have been hundreds of other people on 285 with us that could have seen it.
