Pre-Dawn Green Fireball Over Moscow Under Review, Asteroid Seen as Likely

A preliminary analysis by Russia's space institute points to an asteroid origin.

Overview

  • Multiple videos from Moscow and nearby towns show a vivid green object that fragmented and left a persistent trail before fading just after 06:32 local time on October 27.
  • The Space Research Institute (IKI) estimated a speed between 14 and 30 km/s on a west‑to‑east path north of the city, a range consistent with a meteoroid or small asteroid.
  • IKI stressed the finding is provisional as some Russian specialists continue to suggest the object was re-entering space debris.
  • Public re-entry trackers listed no artificial objects expected over European Russia at that time, a gap that analysts say favors a natural bolide pending confirmation.
  • No injuries, damage, sonic booms or recovered fragments have been reported, and the sighting coincided with the active Orionid and Southern Taurid meteor streams.
