Meet Bennu!

Bennu is a special space rock that scientists watch very closely. It was found on September 11, 1999, by the LINEAR Project. Bennu is named after an ancient Egyptian mythological bird linked to the Sun, creation, and new beginnings.

Bennu is about the size of a big football field, roughly 490 meters wide. Scientists study it using special telescopes like the Arecibo Observatory and the Goldstone Deep Space Network. It was the focus of the OSIRIS-REx mission, a spacecraft that visited Bennu and collected samples to bring back to Earth. These samples help scientists learn about space and our Solar System.

Bennu spins like a top and has big rocks on its surface. It also has water hidden inside, which is very exciting for scientists. All the features on Bennu are named after birds and bird-like creatures from myths from around the world.

Scientists think Bennu might come very close to Earth in the future, so they keep watching it carefully. Even though there are some possible close approaches, there is no need to worry right now. Bennu helps us learn more about space rocks and our amazing universe.
