How are UFO encounters classified and what are the different categories of sightings?

UFO encounter classification systems organize sightings and experiences into systematic categories based on distance, interaction level, and phenomena characteristics, with the most widely used being J. Allen Hynek’s Close Encounter system (CE-1 through CE-5), Jacques Vallee’s scientific classification scheme, government UAP categories, and specialized taxonomies that help researchers analyze patterns, compare cases, and maintain consistent documentation standards across the global UFO research community.
