Small asteroid hit Earth’s atmosphere over Siberia today


This weather webcam out of Russia shows the small asteroid as it hit Earth’s atmosphere over Siberia around 16:14 UTC (10:14 a.m. CST December 3 and 1:14 a.m. local time December 4) today.

Small asteroid hit Earth’s atmosphere today

This morning (05:55 UTC on December 3, 2024) astronomers discovered a small asteroid, somewhere in size between 0.5 to 1.2 meters (1.6 to 4 feet) … and it’s already struck Earth. The asteroid, first named C0WEPC5 and now officially designated 2024 XA1, harmlessly entered Earth’s atmosphere around 16:14 UTC (10:14 a.m. CST December 3 or 1:14 a.m. local time on December 4) over Eastern Siberia. This tiny asteroid created a nice fireball in dark skies. It’s possible small fragments reached the ground.

You may recall the impressive Tunguska event – when a large asteroid created an airburst that flattened hundreds of square miles of trees in 1908 – also happened in Eastern Siberia. Today’s event was much, much smaller. It would have hit at about the same latitude and around 18 degrees further east, or about a thousand kilometers away from the famous event.

According to NASA’s Asteroid Watch, astronomers first made the discovery:

… with the University of Arizona’s Bok telescope by the NASA-funded Catalina Sky Survey and Spacewatch. The impact prediction was made by the Scout system at NASAJPL’s Center for Near-Earth Object Studies (CNEOS).

The incoming asteroid had a velocity of about 9.6 miles per second (15.5 km/s) with a moderate angle of 58 degrees. And it came in from the southeast. According to Sam Deen’s predictions on the Minor Planet Mailing List, it might have been possible for people in Yakutsk, Mirny, Norilsk or Dudinka to see it.

Sightings of the asteroid shared on social media

The small asteroid made a pretty bright splash in the night sky over Siberia. Here’s a video from Bluesky:

4th asteroid to hit Earth’s atmosphere in 2024

This is only the 11th time ever and the 4th time this year that astronomers have spotted an asteroid just before it crashed into Earth’s atmosphere. Earlier this year a 3 feet (1 meter) asteroid hit over the Pacific Ocean on October 22, and another one of similar size struck the atmosphere above the Philippines on September 4. And the first one this year hit above Germany on January 21.

With our increasing technology, we are able to spot more of these little asteroids before they hit us. According to NASA:

Every day, Earth is bombarded with more than 100 tons of dust and sand-sized particles. About once a year, an automobile-sized asteroid hits Earth’s atmosphere, creates an impressive fireball, and burns up before reaching the surface.

Bottom line: A small asteroid harmlessly hit Earth’s atmosphere over Siberia in Russia today. More info with a map and images of the fireball here.
