The successor to this mission, called Hayabusa2, was completed near the end of 2020, bringing back material from Asteroid 162173 “Ryugu,” along with a collection of images and data gathered ...

In 2020 the space mission Hayabusa2 returned samples and images from the space rock Asteroid 162173 or Ryugu, classified as a potentially hazardous asteroid (PHA) by NASA 's Center for Near-Earth ...

Minor planet 162173 was discovered by LINEAR in 1999, provisionally named 1999 JU3, and quickly found to be a potentially hazardous object (PHO) in the Apollo group of Earth-crossing asteroids. It ...
