I was visiting my daughter and watching my grandson at a play area. i was sitting on a bench facing ne. i leaned back and was looking ne into the clear blue sky. then i realized that there was a very tiny bright light high in the sky and i happened to be looking right at it. otherwise, i would have never seen it, being so small. it remained stationary for about 30 min. and then it began to move away into the distance and out of sight. this location in one a commercial airline flight path into atlanta airport. several planes went over between me and the object. the planes were at about 10,000 ft. the object was 10 times that distance. i appeared to me that it was actually a very large object at over 100,000 feet.
