Ryugu is a near-Earth object and a potentially hazardous asteroid of the Apollo group. It measures approximately 900 metres (3,000 ft) in diameter and is a dark object of the rare spectral type Cb, with qualities of both a C-type asteroid and a B-type asteroid.

In June 2018, the Japanese spacecraft Hayabusa2 arrived at the asteroid. After making measurements and taking samples, Hayabusa2 left Ryugu for Earth in November 2019 and returned the sample capsule to Earth on 5 December 2020.

The samples showed the presence of organic compounds, such as uracil (one of the four components in RNA) and vitamin B3.

    what if vitamin b3 is really just asteroid material 🤔 and we have part asteroid in us, instead of them having part of us 😌

      We’re made of supernova material. I think that’s cooler anyway.
