Phases and Information Moon phases There are 8 moon phases narcycles/lunarapplet.htmlnarcycles/lunarapplet.html How many days? Each moon phase last about 3.3 days New moon to New moon The full cycle from New moon to New moon takes 29.5 days Happy Birthday! Age of the Moon 4.5 billion years old Moon Rotation The same side of the Moon always faces the Earth. The Moon's rotation period is synchronous with its revolution period around the Earth. Change of Distance Because of a loss of orbital energy to gravity from the Earth, the Moon is very gradually moving away from the Earth. Lunar Atmosphere The Moon has almost no atmosphere, because of its weak gravity. All types of gas will escape from its surface. Moon temperature The surface temperature fluctuates from roughly +300 F to -270 F! Blue Moon When two full moons occur in a single month, the second full moon is called a "Blue Moon." A Moon by any other name CalledLuna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies.LunaSelene Artemis You wobble too? the Moon appears to wobble a bit so that a few degrees of the far side can be seen.wobble USSR The moon was first visited by the U.S.S.R.'s Luna 1 and Luna 2 in 1959, and a number of U.S. and U.S.S.R. robotic spacecraft followed. Luna 1Luna 2 Shine On! The Moon reflects the light of the Sun. Moon axis The Moon does spin on its axis, completing a rotation once every 27.3 days. It also takes the same period to orbit the Earth, the same side faces us. Two-faced The Moon has no side that is constantly dark; the front and back are alternately lit as the Moon rotates. Far side is a more accurate term.
