Disambiguation: Meteor refers specifically to the atmospheric phenomenon (luminous streak). Distinct from meteoroid (space object before atmospheric entry) and meteorite (surviving fragment that reaches ground). In physics: location-dependent terminology for the same space rock.

A meteor is a luminous phenomenon created when a meteoroid (small natural space rock) enters Earth's atmosphere at speeds around 30 km/s and burns up through friction with air molecules at altitudes of 75–120 km, commonly called a 'shooting star.' Meteors range in brightness from dim streaks to fireballs (magnitude −4 or brighter) and bolides (magnitude −14 or brighter, occasionally exploding). Most visible meteors originate from meteoroids roughly the size of sand grains (1 mm or smaller). In UAP/UFO investigation contexts, meteors rank among the most frequently cited natural phenomena misidentified as unidentified aerial objects, particularly under adverse visibility conditions, cloudy skies, or optical illusion scenarios.

Um meteoro é um fenômeno luminoso criado quando um meteoroide (pequena rocha espacial natural) entra na atmosfera terrestre em velocidades ao redor de 30 km/s e se queima pela fricção com moléculas de ar em altitudes de 75–120 km, comumente chamado de 'estrela cadente'. Meteoros variam em brilho desde rastros tênues até bolas de fogo (magnitude −4 ou mais brilhante) e bolides (magnitude −14 ou mais brilhante, ocasionalmente explodindo). A maioria dos meteoros visíveis origina-se de meteoroides aproximadamente do tamanho de grãos de areia (1 mm ou menores). Em contextos de investigação de UAP/OVNI, meteoros figuram entre os fenômenos naturais mais frequentemente identificados erroneamente como objetos aéreos não identificados, particularmente sob condições adversas de visibilidade, céus nublados ou cenários de ilusão de ótica.
