Bright light moving slowly across the sky

While I was outside on my back porch having coffee, I noticed a very large bright light in the sky towards the North side of the State. When I first spotted it, it was sitting in the air not moving. I watched it for about a minute and it slowly began moving towards the West and eventually disappeared from my view towards the West. The object also made no sound that I could tell, although it did seem to be very far away, given its brightness.
