Unidentified flying object
(Redirected from UFO)
An unidentified flying object (or UFO) is an object in the sky which cannot be identified.
Identified flying objects (IFOs)
[change | change source]Studies estimate that 50-90% of all reported UFO sightings are identified later. Most are natural or man-made objects that looked strange. 80-90% of UFOs are identified as one of three things:
- astronomical causes (for example: planets, stars, or meteors)
- aircraft
- balloons (including weather balloons)
New term
[change | change source]Since the 2020s, people have come up with the following terminology:
- Unidentified Aerial Phenomena
- Unidentified Anomalous Phenomena
Therefore, it is common to hear "UFO" and "UAP" while listening to people talk about this topic.[1][2]
