In July 2025, the ATLAS sky survey in Chile spotted a faint comet racing through the solar system at roughly 130,000 miles per hour — and follow-up orbit calculations quickly showed it was not bound t

Astronomers have identified 3I/ATLAS, a rare interstellar object passing through our solar system at record-breaking speeds. Unlike typical comets, its hyperbolic trajectory confirms it originated from outside our solar system.
Why it matters
Studying interstellar objects provides scientists with unique data about the composition and characteristics of other planetary systems.
On July 1, 2025, the ATLAS survey telescope in Rio Hurtado, Chile, reported a faint moving object to the Minor Planet Center.
The report is purely scientific and factual, focusing on astronomical observations.
