See it on NASA's siteComet 3I/ATLAS is an interstellar comet, only the third known interstellar object to pass through our solar system. Studying it helps us understand how typical our solar system is. This comet appears relatively normal compared to solar system comets, with a similar chemical composition and dust ejection.
