These findings suggest that Ryugu was once part of a much larger asteroid that formed out of various materials some two million years after our Solar System (some 4.5 billion years ago).

Ryugu broke off from a larger asteroid after Earth had formed. But, he said, its parent body was an ancient asteroid that broke up, and bits could have traveled to the inner solar system, with ...

Item 1 of 3 The carbonaceous asteroid Ryugu is seen from a distance of about 12 miles (20 km) during the Japanese Space Agency's Hayabusa2 mission on June 30, 2018.

With the understanding that water existed on Ryugu's parent asteroid getting more and more backing, a second team led by Hiroshi Naraoka looked at organic molecules that are soluble in water.

Samples taken from the space-returned piece of asteroid Ryugu were collected and prepared under strict anti-contamination controls. Inside the cleanest of clean rooms, a tiny particle was collected… ...
