The Moon (Luna) is the Earth's solitary satellite, and is not believed to harbor any life.
10 THINGS ABOUT THE MOON
Birth When the moon was formed, it was around 22.530 kilometres from earth. Now it's more than 450.000 kilometres away. The moon uses Earth's rotational energy to propel itself 3.8 centimetres higher in orbit each year.
Theory According to one theory, the moon was created when a rock the size of Mars slammed into the Earth over 4.5 billion years ago.
Earthquakes The moon has earthquakes. Apollo astronauts used seismometers to find that small "moonquakes" originate several kilometres below the surface, sometimes causing gas to escape on the surface.
Size The diameter of the moon is 1/4 that of Earth's.
Surface The moon's surface is full of craters that are as wide as 225 kilometres in diameter and 4,500 metre deep.
Temperatures on the moon can reach 123C is sunlight, or drop to -153C on the "Dark side of the moon".
Shape The moon is not round, but egg-shaped with the large end pointed towards us.
View From Earth we always see the same side of the moon even though both are orbiting.
Mass The core of the moon is only 2%-4%of its mass. The iron core of Earth makes up 30%of the planet's mass.
Gravitation All the gravitational pull the moon has on Earth causes some of Earth's energy to be stolen by the moon. Our planets rotation slows down by about 1.5 milliseconds every century.
The Moon has had no known visitors since the end of the Apollo program in 1972. America's NASA, the European Space Agency and the Chinese space program all have apparently serious plans to return, but none are in a hurry: NASA's target date for the next man on the moon is 2018, while both the ESA and the Chinese are aiming at 2024. India has also expressed its hope to send a manned mission to the Moon by 2020.
If you're content with just taking a closer look, Space Adventures and the Russian Space Agency have floated the idea of a flight around the moon for a cool US$100 million or so; see Space for details. Virgin Galactic will develop the Virgin SpaceShip to bring people to space.
Conventional aircraft are useless on the Moon since there is no atmosphere to generate the aerodynamic lift they require to fly. The primary method of transportation has been lunar rovers, three of which are still stranded at Mons Hadley, the Descartes Highland and the Taurus-Littrow valley.
Gravity on the Moon's surface is only one-sixth of the Earth, which compensates in part for having to wear a bulky pressurized spacesuit.
Rock collecting is the most obvious hobby, and it's easy to do since the Moon is one giant rock. Dust collecting is also a favorite among tourists.
Play golf. There are no established golf courses available, but the moon does provide you with an excellent opportunity to practice your sand trap shots.
Do the moonwalk. Could be tricky in a space-suit, but there is no better place to do it.
Get some space junks (there are a total of almost 180 tons waiting to be salvaged) that were intentionally crashed by some space agencies on the moon. They could be yours, pretty cool stuff for a garage sale.
The new moon tour company has designed special shops to be sold on the moon for the tourists.
Due to the fact that there are no humans on the moon, there is also no crime problem.
The universe however is out to get you and this will become all too apparent once you leave the comforts of Earth. In addition to the obvious problems of freezing cold temperatures and the lack of a breathable atmosphere, in order to stay alive you will have to take precautions:
Solar storms (there is no magnetic field to deflect these high energy particles)
Meteor impacts (there is no atmosphere to burn them before they impact the surface)
