Disambiguation
NOT to be confused with: (1) ordinary meteors/shooting stars (too faint); (2) bolides (fireballs that explode with visible fragmentation); (3) artificial debris or satellite re-entry. In UFO/UAP historical context, 'green fireballs' specifically denote the class of luminous phenomena reported 1948–1951 in southwestern US, distinct from natural meteorological fireballs by reported anomalous behavior (directional changes, sustained hovering).

Concept
An exceptionally bright meteor (visual magnitude −3 or brighter) produced by large meteoroids entering Earth's atmosphere at high velocity. In UFO/UAP historical context, refers also to anomalous luminous phenomena—especially the 'green fireballs' of 1948–1951 southwestern US—exhibiting behavioral characteristics (directional changes, sustained altitude, lack of smoke) inconsistent with natural bolides.
Um meteoro excepcionalmente brilhante (magnitude visual −3 ou mais brilhante) produzido por grandes meteoroides entrando na atmosfera terrestre em alta velocidade. No contexto histórico de UFO/UAP, refere-se também a fenômenos luminosos anômalos—especialmente os 'green fireballs' de 1948–1951 no sudoeste dos EUA—exibindo características comportamentais (mudanças direcionais, altitude sustentada, falta de rastro de fumaça) inconsistentes com bolides naturais.

Fireball is an astronomical and UAP classification term denoting an exceptionally bright meteor reaching visual magnitude −3 or brighter. Scientifically, fireballs are caused by large meteoroids entering Earth's atmosphere at high velocity, heating through air compression rather than friction. In historical UFO/UAP records, the term also encompasses anomalous luminous phenomena—particularly the 'green fireballs' reported 1948–1951 over New Mexico and sensitive military installations—which exhibited behaviors (directional control, sustained altitude, lack of smoke trail) inconsistent with natural bolides. Project Twinkle, established by the US military in December 1949 to study these objects, ultimately concluded their origin remained undetermined. Fireballs remain a persistent category in modern UAP classification and Pentagon documentation.

Fireball é um termo de classificação astronômica e UAP que denota um meteoro excepcionalmente brilhante com magnitude visual de −3 ou mais brilhante. Cientificamente, fireballs são causados por grandes meteoroides entrando na atmosfera terrestre em alta velocidade, aquecendo-se pela compressão do ar em vez de fricção. Em registros históricos de UFO/UAP, o termo também abrange fenômenos luminosos anômalos—particularmente os 'green fireballs' reportados de 1948–1951 sobre New Mexico e instalações militares sensíveis—que exibiram comportamentos (controle direcional, altitude sustentada, falta de rastro de fumaça) inconsistentes com bolides naturais. O Projeto Twinkle, estabelecido pelo exército americano em dezembro de 1949 para estudar esses objetos, concluiu que sua origem permanecia indeterminada. Fireballs permanecem uma categoria persistente na classificação moderna de UAP e documentação do Pentágono.
