Having just passed perihelion — its closest approach to the sun — comet 3I/ATLAS has re-emerged from behind the sun, offering astronomers a rare glimpse of its unusual composition and structure.

C2025/K1 (ATLAS) will be closest to the Earth on November 25.

Comet C/2025 K1 (ATLAS) defies odds, glows golden after close encounter with the Sun

C/2025 K1 (ATLAS), a comet that was believed to disintegrate because of its closeness to the Sun, has surprised astronomers by surviving and changing its colour from green to a rare golden hue.

The unusual event was detected by several space-based observatories, including the Solar and Heliospheric Observatory (SOHO), the GOES-19 meteorological satellite, and NASA’s twin spacecraft, STEREO-A and STEREO-B (Solar Terrestrial Relations Observatory).(Image for representation: Unsplash)

Unprecedented brightening of interstellar Comet 3I/ATLAS reported in new research

The finding is significant because the internal composition of 3I/ATLAS could suggest that the planetary system from which it originates has a unique chemical makeup.

According to Nasa, this is a comet. It will stay at least 1.6 astronomical units away from Earth and is not a threat. About 150 million miles separate them. (Image: Nasa Science)

Comet 3I/ATLAS to reach closest point to the Sun today; NASA to monitor peak outgassing activity
