Discovery

Ryugu was discovered in 1999 by the LINEAR project, and was given the provisional designation 1999 JU3.

Name

The asteroid was officially named Ryugu on 5 October 2015. Its name refers to Ryūgū-jō (Dragon's Palace), a wonderful and magical palace on the bottom of the ocean where Urashima Tarō, in a Japanese folktale, was brought by a turtle. When he returned, he brought back with him a mysterious box—much as Hayabusa 2 will bring back a capsule with samples.

Value

Planetary Resources speculates that the current value of the asteroid for mining purposes as of July 2016 is $95.02 billion.
