Using the classic doubly-tangent Hohmann minimum-energy transfer orbit, it
takes almost exactly 72 hours (3 days) to get from Earth orbit to Lunar
orbit. In the Gundam universe, this means from Earth to the Moon, Luna II
(L3), L4 or L5.

Here it gets a bit tricky. L4 (Side 6) is in the same orbit as the Moon,
60 ahead (east) of it. L2 (Side 3) is 60,000 km on the other side of the
Moon from Earth. L4, Earth and Moon are equidistant from each other, but
as noted in previous posts the delta-V is vastly different. I estimate 60
hours (2.5 days) each way to get from Side 6 (Riah) to Side 3 (Zeon).

That'll still work with the longer transit time, but Bernie's gonna have
world-class jet-lag, with most of his time (120 hours or 5 days) spent in
