Description: Today’s two stroy:
- One meter diameter 2022 WJ1 holds the record as the smallest asteroid ever detected! It even hit the ground as it entered Earth’s atmosphere.
- – Very small fast moving asteroids pass through our solar system.About once a month an object like 2023 KU4 enters our atmosphere, releases the energy of approximately 2.4 tons of TNT, explodes at an altitude of about 280,000 feet, creates a spectacular light show, produces a sonic boom that is barely audible, and rains pieces of itself on the ground for meteorite hunters to discover. Check out the fireball log on the American Meteor Society website for examples.
