Asteroid Ryugu. Ryugu is what’s called a C-type or carbonaceous asteroid. These are the most common type in the asteroid belt, making up about 75 percent of the asteroids we can see.

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.
