This week, the estimated orbit concluded that the Hayabusa would be on the path skimming
the Moon orbit this June. The closest approach distance from the Earth is found 470
thousand kilometers, just above the Moon's orbit. Now the goal for reentry has loomed
eventually.


Fig.1: Closest distance to Earth when Hayabusa flies ballistically from the moment designated.

Fig.2: The plane is normal to the approach velocity to Earth, and the horizontal axis corresponds to a crossing line with the equatorial plane. Sun is in the left hand side. Plots show the points where Hayabusa flies through this plane.

Fig.3: Trajectories relative to Earth in inertial frame. The plane corresponds to the ecliptic plane.

Notes: Dates designated in the left figure do not indicate the return dates.
