Comet C/2025 A6 Lemmon | International Space Station

Comet C/2025 A6 Lemmon | International Space Station





Expedition 73 flight engineer and Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui: "Good morning, everyone! I'm sorry for talking about comets so much lately, but today's scenery was also spectacular, so please allow me to introduce it.  

It was dancing so gorgeously through the pre-dawn universe that it was too magnificent to call Lemon-chan, so today I'll refer to it as Lemon-san lol.  

It was just like a mermaid swimming through a sea of auroras.

After a busy day comes to an end, I've been continuing to take photos to soothe my fatigue. Lately, my source of healing has been Lemon-chan, I suppose? lol."

Comet Lemmon is brightening and moving into morning northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures. Comet Lemmon was discovered early this year and is still headed into the inner Solar System. The comet will round the Sun on November 8, 2025. It passed nearest to the Earth—about half of the Earth-Sun distance—on October 21.
