Origin Beyond Our Solar System
According to NASA, 3I/ATLAS is an interstellar comet visiting our solar system for the first time. Its hyperbolic orbit shows it comes from a distant star system, making it a rare and valuable visitor to study.

Unusual Carbon Dioxide Levels
According to the James Webb Space Telescope findings, 3I/ATLAS contains much more carbon dioxide than water ice compared to regular comets. This unusual chemical mix provides clues about its origin in a carbon-rich environment.

Early Activity Far From the Sun
According to ESA, the comet began releasing gases and dust at over 6 AU from the Sun, much earlier than typical comets. This hints at the presence of highly volatile ices that sublimate at greater distances.

Larger Than Expected
According to the Vera C. Rubin Observatory, 3I/ATLAS measures up to around 5.6 km across, making it one of the largest interstellar objects ever recorded, larger than the first known ‘Oumuamua.

Safe Near Pass to Earth
According to ESA, 3I/ATLAS will stay at a safe distance of around 1.8 AU from Earth, eliminating any risk of collision. This close approach offers a unique chance to observe an interstellar visitor up close.
