Asteroid Ryugu contains material older than the planets, some of the most primitive ever studied on Earth

The asteroid Ryugu contains some of the most primitive materials ever studied in a lab on Earth, dating back just 5 million years after the solar system formed, according to an analysis of samples recovered by Japan’s Hayabusa2 mission.

Because it is so old, it is made of the same material that formed the planets. “Ryugu is one of the building blocks of the Earth,” team member Hisayoshi Yurimoto, a professor at Hokkaido University in Japan, told Space.com.
