The mostaccepted theory about the origin of the Moon is that it was formed of the debris from a massivecollision with the young Earth about 4.6 billion years ago. A huge body, perhaps the size of Mars,struck the Earth, throwing out an immense amount ofdebris that coalesced and cooled in orbit aroundthe Earth.The development of Earth is inextricably linked to the moon; the Moon's gravitational influenceupon the Earth is the primary cause of ocean tides. In fact, the Moon has more than twice the effectupon the tides than the Sun does. The Moon makes one rotation and completes a revolution around theEarth every 27 days, 7 hours, and 43 minutes. This synchronous rotation is caused by an unevendistribution of mass in the Moon (essentially, it is heavier on one side than the other) and has allowedthe Earth's gravity to keep one side of the Moon permanently facing Earth. It is an average distancefrom Earth of 384,403 km.The Moon has no atmosphere; without an atmosphere, the Moon has nothing to protect it frommeteorite impacts, and thus the surface of the Moon is covered with impact craters, both large andsmall. The Moon also has no active tectonic or volcanic activity, so the erosive effects of atmosphericweathering, tectonic shifts, and volcanic upheavals that tend to erase and reform the Earth's surfacefeatures are not at work on the Moon. In fact, even tiny surface features such as the footprint left by anastronaut in the lunar soil are likely to last for millions of years, unless obliterated by a chancemeteorite strike. The surface gravity of the Moon is about one-sixth that of the Earth's. Therefore, aman weighing 82 kilograms on Earth would only weigh 14 kilograms on the Moon.The geographical features of the Earth most like that of the Moon are, in fact, places such as theHawaiian volcanic craters and the huge meteor crater in Arizona. The climate of the Moon is veryunlike either Hawaii or Arizona, however; in fact the temperature on the Moon ranges between 123degrees C. to -233 degrees C.
