Calculation breakdown
Circular-orbit eclipse geometry
Eclipse occurs where the circular orbit cuts through the central body shadow.
36.11 min
Eclipse duration
36.11 min
39.01% of each orbit
Half-angle
70.218 deg
angular span from shadow centerline to contact
Critical beta
70.22 deg
above this magnitude, the circular orbit avoids eclipse
