Hypersonic Interstellar Comet 3I/ATLAS: A Record-Breaking Visitor
2025-07-03
Astronomers have discovered the third interstellar object, 3I/ATLAS, originating outside our solar system. This comet is remarkably fast, traveling at 60 kilometers per second towards the Sun, far exceeding previous interstellar visitors. Its orbit is largely unaffected by the Sun's gravity, giving scientists at least eight months of observation time. Unlike 'Oumuamua and 2I/Borisov, 3I/ATLAS's discovery, coupled with the capabilities of future telescopes like the Vera C. Rubin Observatory, suggests a significant increase in the detection rate of interstellar objects—potentially several per year.
