This animated GIF was generated using radar data collected by the National Science Foundation's 1,000-foot (305-meter) Arecibo Observatory in Puerto Rico. The six radar images used in the animation were taken on Oct. 30, 2015, and the image resolution is 25 feet (7.5 meters) per pixel.

The celestial object is more than likely a dead comet that has shed its volatiles after numerous passes around the sun.
