Astronomers Find the Smallest Asteroids Ever Detected in the Main Belt Dec. 9, 2024 — Astronomers have found a way to spot the smallest, 'decameter,' asteroids within the main asteroid belt.
The head of planetary defense at the European Space Agency discusses 2024 YR4, an asteroid with a small chance of striking ...
The best modern comparison is the 1908 Tunguska Event, when an asteroid or comet fragment measuring 30-50 meters exploded over Siberia, flattening 80 million trees across 770 square miles.
The comet was only first discovered on April 5 last year by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey. "Preliminary orbital calculations suggest this is likely a long-period ...
A dive into probabilities, asteroid impact modeling, and what sort of damage an approximately 180-foot asteroid could cause ...
Should this keep you up at night? “No, absolutely not,” said David Rankin, a comet and asteroid spotter at the University of Arizona. The object’s current odds of striking Earth may sound ...
Great question! Assuming you’re referring specifically to the orbital period — in other words, how long comets take to make one revolution around the Sun, or a cometary “year ...
NASA and European scientists explain how they calculate the probability of the space rock 2024 YR4 impacting our planet, and why it’s not yet time to worry.
