Ryugu

Definition

Ryugu is a near-Earth asteroid that was the target of the Hayabusa2 mission launched by the Japan Aerospace Exploration Agency (JAXA). This asteroid is notable for its diamond-like shape and dark surface, which consists of carbon-rich materials, providing valuable insights into the early solar system and the building blocks of life. The study of Ryugu has implications for emerging fields like planetary defense and the exploration of organic compounds in astrobiology.
