Interstellar Comet 3I → ATLAS: A Rare Visitor to Our Solar System The detection of interstellar objects (ISOs) has opened a new window into the study of our solar system and beyond. Recently, NASA's ATLAS (Asteroid Terrestrial-impact Last Alert System) survey detected an ISO, designated 3I → ATLAS, also known as "Comet C → 2025 N1 (ATLAS)" and initially dubbed A11pl3Z (Knight, 2025). This object is the third confirmed interstellar object ever detected, following 'Oumuamua (Meech et al., 2017) and 2I → Borisov (Guzmán-Sánchez et al., 2019). ## Characteristics and Trajectory of 3I → ATLAS 3I → ATLAS is traveling at an extremely high speed of approximately 245,000 km → h (or 152,000 mph) at its fastest approach, making it one of the fastest objects ever recorded in our solar system (Kelley et al., 2025). Its path is hyperbolic, meaning it is not gravitationally bound to the Sun and is just passing through before exiting the solar system (Jewitt et al.
NASA is tracking an object that is entering the solar system at approximately 245,000 km/h. This interstellar visitor is 3I/ATLAS, also known as ...Here's one of the sources related to this article: See here
