Different kinds of rocks on Ryugu provide clues to the asteroid’s turbulent history. Researchers find evidence that asteroid Ryugu was born out of the possible destruction of a larger parent asteroid millions of years ago. Thanks to the Hayabusa2 spacecraft, the international team was able to study certain surface features in detail. Variations in the kinds of boulders scattered on Ryugu tell researchers about the processes involved in its creation. The study of asteroids including Ryugu informs the study of the evolution of life on Earth.

The asteroid Ryugu may look like a solid piece of rock, but it’s more ...

The solar system formed approximately 4.5 billion years ago. Numerous fragments that bear witness to this early era orbit the sun as asteroids. Around three-quarters of these are carbon-rich C-type asteroids, such as 162173 Ryugu, which was the target of the Japanese Hayabusa2 mission in 2018 and 2019. The spacecraft is currently on its return flight to Earth...
