Disc of fire seen in the sky close to harisburg

As i was driving West on Interstate 76, It was NewYears Eve.. there was really no one else on the road except for me in that remote area and the holiday. I spotted ahead of me, what looked liked a "Disc of Fire.." it was orange/Reddish.. I kept watching it as i approached. It was just hanging up in the sky. It was no Helicopter, No Airplane, and i was in the middle of nowhere pretty much. As i got underneath of it, i had the moon roof open, and it was if i was looking up into a Burning Kettle /pot of molten Steel.. It was that color.. And Orangish /Red. I was looking at a sphere of fire. It was the oddest thing i've ever seen. I kept looking for it after i passed, but did not see it after that. I will never forget it.. Just hovering up in the dark night.
