Three bright spheres in Drake, Colorado

I was laying in bed, and since I have a skylight I was looking out at the stars. It was a very clear night. Suddenly, I saw three white orb-looking objects forming a triangle. They flew right over my house and at a slight distance away. They moved slow, and did not blink at all. However, the outside edges of the spheres seemed to spin and just didn't look normal. They flew towards the mountain until they were out of my sight. I watched for it to come back, but it never did.
