(1,0 pt)A UFO (Unidentified Flying Object) is any object flying in the sky which cannot be identified bythe person who sees it. Sometimes the object is investigated. If people can still not figure out what theobject is after an investigation, it is called a UFO. If they figure out what the object is, it can no longerbe called a UFO because it has been identified.Even though UFOs can be anything, people often use the word UFO when they are talking aboutalien spacecraft. Flying saucer is another word that is often used to describe an unidentified flyingobject.Studies estimate that 50%-90% of all reported UFO sightings are identified later. Usually10%-20% are never identified. Studies also show that very few UFO sightings are hoaxes (peopletrying to trick other people). Most UFOs are actually natural or man-made objects that looked strange.80%-90% UFOs are identified as one of three different things: astronomical causes (for example:planets, stars, or meteors); aircraft; balloons. 10%-20% of UFOs are other causes (such as birds, clouds,mirages, searchlights, etc.)
