Hayabusa 2 is a JAXA sample-return mission launched to the asteroid 162173 Ryugu on 2014-Dec-3. It arrived on Ryugu in 2018-Dec-31 and collected samples from the asteroid twice in the following year. During its two year stay at Ryugu, it deployed three MINERVA-II "rovers" and the MASCOT hopper, before returning to Earth on 2020-Dec-6.

It is now on its extended mission to study two asteroids, 2001 CC₂₁ and 1998 KY₂₆, on two subsequent encounters on 2026 and 2031 respectively


  • Hayabusa2's primary mission from 2014 to 2019 requires the asteroid 162173 Ryugu installed first on Celestia
  • For the two asteroid flybys on its extended mission on 2026 and 2031, download the asteroids named 98943 (2001 CC₂₁) and (1998 KY₂₆)
  • Due to currently limited trajectory data, the actual flyby of 1998 KY₂₆ will not (yet) occur, but the last known orbital data enables the spacecraft to at least share a common orbit with the asteroid around the Sun
