Join FYM News as we unravel the story of Comet 3I/ATLAS, bringing you the latest updates and scientific discoveries about this fascinating interstellar traveler.
Comet 3I/ATLAS: An Overview
Comet 3I/ATLAS is classified as an interstellar object due to its hyperbolic orbit, indicating it does not orbit the Sun but rather passes through our solar system on a one-way journey. Originating from outside our solar system, tracing its path backward confirms its extrasolar origins. It poses no threat to Earth, with its closest approach being about 1.8 astronomical units (AU), approximately 170 million miles (270 million kilometers) away. The comet will reach its nearest point to the Sun around October 30, 2025, at about 1.4 AU (130 million miles, or 210 million kilometers), slightly inside Mars’ orbit.
Currently, astronomers globally are investigating the physical properties of Comet 3I/ATLAS. Ground-based telescopes are expected to observe it until September 2025, after which it will be too close to the Sun. Observations should resume by early December 2025, offering further opportunities for study. According to NASA, the interstellar comet’s size and physical properties are being investigated by astronomers around the world.

The Discovery of Comet 3I/ATLAS
The discovery of Comet 3I/ATLAS was made by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope in Rio Hurtado, Chile, on July 1, 2025. Funded by NASA, ATLAS reported its findings to the Minor Planet Center. Subsequent analysis included pre-discovery observations from ATLAS telescopes and Caltech’s Zwicky Transient Facility, extending back to June 14, 2025. The name reflects its origins: “I” for interstellar, “3” as the third such object, and ATLAS, after the discovery team.
Comets are typically named after their discoverers, and in this case, the ATLAS survey team earned the honor. The designation ‘I’ signifies its interstellar nature, marking it as an object originating from beyond our solar system. As the third interstellar object of its kind to be identified, it receives the designation ‘3’ in its name. This naming convention provides a clear indication of the comet’s unique origin and sets it apart from comets formed within our solar system.
NASA Assets Observing Comet 3I/ATLAS
NASA’s Hubble Space Telescope captured an image of Comet 3I/ATLAS on July 21, 2025, at a distance of 277 million miles from Earth. The image revealed a teardrop-shaped cocoon of dust emanating from its icy nucleus. The Hubble’s tracking of the comet’s hyperbolic trajectory caused background stars to appear streaked. As of August 20, 2025, observations suggest the comet’s nucleus has a diameter between 1,444 feet (440 meters) and 3.5 miles (5.6 kilometers).
Several NASA assets, including Hubble, Webb, TESS, Swift, SPHEREx, Perseverance Mars rover, Mars Reconnaissance Orbiter, Curiosity rover, Europa Clipper, Lucy, Psyche, Parker Solar Probe, PUNCH, and ESA/NASA’s SOHO and Juice, are scheduled to observe Comet 3I/ATLAS. These observations aim to gather comprehensive data on the comet’s composition, behavior, and trajectory as it traverses our solar system. This collaborative effort will enhance our understanding of interstellar objects and their potential impact on our cosmic neighborhood.
Comet 3I/ATLAS’s Mars Flyby
In early October, Comet 3I/ATLAS is set to fly by Mars, presenting a unique opportunity for multiple spacecraft in Martian orbit to observe this interstellar visitor. NASA’s space telescopes, including Hubble, Webb, and SPHEREx, have been actively studying the comet in anticipation of this event. Following its Mars flyby, the comet will pass behind the Sun in late October and venture past Jupiter in March 2026, continuing its journey out of our solar system.
The Mars flyby offers a rare chance to capture close-up observations of an interstellar comet. Spacecraft orbiting Mars may provide valuable data on the comet’s interaction with the Martian atmosphere and its behavior in the vicinity of another planet. These observations will contribute to a more complete understanding of the comet’s composition and physical properties, enriching our knowledge of interstellar objects and their behavior in diverse cosmic environments.
