The moon...
...as a celestial body
O
was probably formed 4.5 billion years ago by the collision of a Mars-sized protoplanet with the early Earth
O
has a smaller mass than the Earth and therefore a lower gravitational pull. Therefore, you could jump six times higher on the moon
O
is 384,000 km away from Earth – for this distance a car would need almost half a year, a spaceship three days, light a good second
O
has no atmosphere – therefore the temperature fluctuates between 130° and – 160° and there is hardly any erosion
...as seen from Earth
O
is only visible because it is illuminated by the sun; depending on the position of the earth, sun and moon in relation to each other, it is sometimes completely visible, sometimes half visible and sometimes not visible at all
O
only ever shows one side to the Earth – we only know the “back” of the moon through space probes
O
requires 29.5 days from full moon to full moon – the basis of the monthly calculation
O
often looks huge when rising - but this "moon magnification" is only an optical illusion
...in its effect on the earth
O
stabilizes the inclination of the Earth's axis and is thus an important element in the creation of the seasons
O
causes ebb and flow
O
slows down the rotation speed of the Earth through the mountains of water that it creates through its gravitational pull - an Earth day without the Moon would only last about 8 hours instead of 24
O
has no effect on the weather, other effects on earth and life are often suspected
