New analysis of samples from asteroid Bennu suggests it formed where inner and outer Solar System material mixed. The study found Jupiter played a role in shaping its formation. The samples are about 4.5 billion years old.
Why it matters: The findings help explain how planets, including Earth, got their building materials.
Samples from asteroid Bennu suggest it formed where material from the inner and outer Solar System mixed. Scientists say Jupiter played a surprising role in shaping its formation. The findings change ideas about how the Solar System formed 4.5 billion years ago.
Why it matters: The samples help scientists understand where the building blocks of planets, including Earth, came from.
