Date of sighting: December 11, 2016
Location of sighting: Orion Nebula
This UFO was reported by UFOmni2012 of Youtube and may be one of the largest UFOs we have reported in a while. How big exactly? If you lined up Earth 100X then you would have a good start. This is one big UFO. Anything seen in Nebulas are usually tremendously huge for us to see from Earth.
