After launch, the Hayabusa2 will fly once around the Sun, in a similar orbit to the Earth’s, then it will come back near the Earth in about one year to perform a swing-by.

After the swing-by, the Hayabusa2 will fly into an orbit that is similar to the 1999 JU3’s. It will make about two rounds around the Sun to arrive at the 1999 JU3. The Hayabusa2 will explore the 1999 JU3 while the asteroid revolves once around the Sun.
