bright lights in the sky hovering for over hours.

I couldn't sleep so I was looking out the window to c if there were any deer in my yard.  I look up at the sky and notcied some green, yellow, and red lights. I thought I was a plane passing.  I looked out and hour later and the craft was still there.  
I woke my mate up to look and he said it was probly a plane. I said it's not moving very much.  He said give it about 15 min and I'll go outside to see.  It was still there, so he went outside and seen lights, he said it was very slow moving but couldn't see what it was. 
I kept looking outside I can still see the lights, and it's been over 2 hours so I know it's not a plane, and the lights are going in a circle.  
I was really scared and just watching it.
