It's only the third object in history from outside our solar system to be discovered cruising through our area of space.
Comet Lemmon was discovered in January 2025 and made its closest approach to Earth in late October 2025. But by November 2025, when this image was taken, it had brightened to about the same apparent brightness as the planet Uranus, making it visible to the naked eye even from suburban skies.
