I was outside smoking a cigarette after work, facing North West. I noticed this object, which I thought was a plane at first. I was looking to see if it had moved. Placing this object with another object to see if it was going farther away. It just stayed in the same spot. During the seventeen minutes of staring at this object I noticed bright green and white spots on the object and two bright lights, and what seemed to be moving up and down.I ran inside to grab binoculars, when I came back the object had moved about three miles more to the North West and farther away. I looked at it through the binoculars and it was a triangular shape. The triangle was outlined in bright green and the center was white. The triangular object was very bright, neon almost. It kept rotating, but stayed the same shape. The object appeared to be spinning every few minutes.I went back inside to grab my phone, which took me about 30 seconds. When I came outside the object was gone. Nowhere in sight. I know what I saw, I can't grasp what I saw. I researched any possibility of it being anything other than a UFO and found nothing. Hoping someone else saw what I saw.Thanks.
