Disambiguation: ATLAS in this corpus refers to 3I/ATLAS, an interstellar comet discovered 2025. Do not confuse with ATLAS telescope surveys (multiple installations) or the Asteroid Terrestrial-impact Last Alert System (the detection platform used for discovery).

3I/ATLAS is an interstellar comet discovered on July 1, 2025, by the NASA-funded ATLAS survey telescope in Río Hurtado, Chile. It is the third confirmed object from beyond our solar system, following 1I/ʻOumuamua and 2I/Borisov. The comet reached closest approach to the Sun on October 29, 2025 (1.36 AU), and passed near Jupiter on March 16, 2026 (0.358 AU). Estimated to be 7–14 billion years old, 3I/ATLAS has attracted scientific interest due to its anomalous composition, particularly its unusually high deuterium ratio (~30× higher than solar-system comets), and its hyperbolic trajectory confirming interstellar origin. In the context of UAP disclosure timelines, 3I/ATLAS coincided with March 2026 transparency initiatives—domains Aliens.gov and alien.gov were registered March 18, 2026, two days after the Jupiter encounter—linking the comet to public disclosure narratives.

3I/ATLAS é um cometa interestelar descoberto em 1º de julho de 2025 pelo telescópio ATLAS (Asteroid Terrestrial-impact Last Alert System), financiado pela NASA, em Río Hurtado, Chile. É o terceiro objeto confirmado de fora do nosso sistema solar, após 1I/ʻOumuamua e 2I/Borisov. O cometa alcançou sua maior aproximação do Sol em 29 de outubro de 2025 (1,36 UA) e passou perto de Júpiter em 16 de março de 2026 (0,358 UA). Estimado ter entre 7 e 14 bilhões de anos de idade, 3I/ATLAS atraiu interesse científico devido à sua composição anômala, particularmente sua razão de deutério incomumente alta (~30× superior à de cometas do sistema solar), e sua trajetória hiperbólica confirmando origem interestelar. No contexto das cronologias de divulgação de UAP, 3I/ATLAS coincidiu com iniciativas de transparência em março de 2026—os domínios Aliens.gov e alien.gov foram registrados em 18 de março de 2026, dois dias após o encontro com Júpiter—vinculando o cometa às narrativas de divulgação pública.
