Asteroid 2018 LA snuck up on our planet and smashed into Earth's atmosphere on June 2. The asteroid mostly burned up, but a team of geoscientists found a fresh meteorite fragment from the visitor and now hope to learn more about its origins.

The under-the-radar asteroid was only about 6 feet (2 meters) across and was spotted just hours before it reached us. It exploded into a eye-catching fireball over Botswana in Africa.
