Bright and slow bolide over Moscow region (Russia) on Oct, 27.

Something man-made over Moscow this morning.

Active #asteriod / main-belt #comet 133P/Elst-Pizarro. This object orbits within the main-belt of asteroids, but shows comet activity.🔭

It was proposed to visit this world with an @esa.int space probe (in 2015/16), but the mission was not selected.

An #asteroid passed just 300 km above Antarctica earlier today. It was not discovered until hours after close approach.

Actuellement deux comètes présentes dans notre système solaire semblent se tirer la bourre. Leur nom de code : C/2025 K1 ATLAS (à gauche) et C/2025 R2 SWAN (à droite). En réalité leurs trajectoires respectives sont très différentes.
