Two bright orange lights

I walked outside and looked up and saw 2 bright orange spheres in the sky over my neighbors house. I stood there for about 8 seconds questioning what I was really seeing. They were very bright and moving really quickly towards the northeast. I yelled for my girlfriend to come outside to check out what I was looking at. When she arrived outside one of the spheres blinked and disappeared the other one did the same about 3 seconds after the first one disappeared. There were multiple aircraft in the sky and none of them were traveling at the speed that these orange spheres were traveling. There was zero noise from these 2 objects. They were moving at least 10 times faster than the commercial planes in the sky. They were flying fairly close to each other but the distance is difficult to determine about how high and close together they were.
