A lunar cycler or Earth–Moon cycler is a cycler orbit, or spacecraft therein, which periodically passes close by the Earth and the Moon, using gravity assists and occasional propellant-powered corrections to maintain its trajectories between the two. If the fuel required to reach a particular cycler orbit from both the Earth and the Moon is modest, and the travel time between the two along the cycler is reasonable, then having a spacecraft in the cycler can provide an efficient an… WebWaning Crescent : Moon phase type: Intermediate. Percentage of Illumination: 50 to zero percent. Description: a thin crescent of light on the left. The dates and times of these phases change each month given the amount of time it takes the Moon to orbit Earth (27 days) and the approximate time it takes to complete one cycle of phases (29.5 days ...

WebThe Moon revolves around Earth in an elliptical orbit with a mean eccentricity of 0.0549. Thus, the Moon's center-to-center distance from Earth varies with mean values of 363,396 km at perigee to 405,504 km at apogee. The lunar orbital period with respect to the stars (sidereal month) is 27.32166 days (27d 07h 43m 12s).
