Two or three times a year, the Full Moon phase coincides with the Moon reaching the lunar nodes of its orbit. These are the points where the Moon’s orbit crosses the ecliptic, which is the Sun’s path, seen from Earth. When this happens, Earth casts its shadow on the Full Moon, ca...
It takes the moon 27 days, 7 hours, 43 minutes and 11.6 seconds to make a complete orbit around the earth. The moon orbits the Earth in a counterclockwise direction. A lunar month is the time it takes the moon to complete all of its phases from New Moon to New Moon. This cycle take...
The new moon appears completely dark and is actually thought of as not visible from Earth because the side we see is the "night" side of the moon or the moon side that is in complete shadow. The moon moves counterclockwise around the Earth, moving from phase to phase about every 3.5 ...
The phases of the moon correspond with the lunar cycle, which is the path that the moon takes as it orbits the Earth. The lunar cycle takes 29.5 days to complete, and during the lunar cycle, the moon moves counterclockwise around the Earth. The lunar cycle is broken up into eight phases...
It is assumed that the velocity increments are applied tangentially to the terminal orbits. The fuel consumption is defined by the arithmetic sum of the velocity increments. The return trip is similarly described with the initial orbit corresponding to LMO and the final orbit corresponding to LEO....
The moon orbits the earth in an elliptical orbit. The moon moves counterclockwise and the same side of the moon always faces towards the earth. However over time the moon moves slightly from north to south and moves unsteadily from east to west. This motion of...

in a retrograde, or counterclockwise orbit around the sun—the opposite orbital direction of the solar system's planets. This causes high-speed, near head-on collisions with the dust particles and the moon's leading surface as the Earth-moon system travel together around the sun, said Horanyi...
