Most commonly reported shapes in UFO sightings gathered by the National UFO Reporting Center Online Database (NUFORC)[1]
This is a list of notable reported sightings of unidentified flying objects (UFOs) and related claims of close encounters or abductions. UFOs are generally considered to include any perceived aerial phenomenon that cannot be immediately identified or explained. Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained.[2][3][4] UFOs have been referred to using a range terms including the more specific "flying saucer" and the more general "unidentified anomalous phenomena" (UAP). The term "UAP" is sometimes used to avoid cultural associations with UFO conspiracy theories.[5][6][7]
NUFORC has collected over 100,000 UFO reports spanning decades. The most common description was of "lights" in the sky, and many UFOs were of an "unknown" or "unspecified" shape. Others included: cubes (16), cones (600), crosses (491), teardrops (1221), and stars (138).
