I was sitting outside, the stars were beautiful, nice clear evening. I noticed two stars that were moving at a fast rate, they were a far distance apart because they were clearly as far away as the stars themselves. They stayed same distance apart moving the same exact rate and distance. I went inside and yelled for my son and his friend to come see them. They could not see them right away, I was pointing up having to move my entire body around to follow them. My son finally seen them and yelled W.T.F? He then was pointing them to his friend who finally watched them with us, the kept moving same rate of speed until they were really dim and then all of a sudden one of them brightened up and then both were out of our eyes reach. I stayed outside for about 45 minutes and observed the sky in all directions and did not see them or anything like it again.
