When you stare at our beautiful Moon tonight don't only appreciate how beautiful it is but also know that we can't live without our Moon (Luna).
Facts:0) The
Moon is considered Huge when compared to Earth (1/4 of the size of the earth). (this is why the Moon has a huge impact on earth).
1)
We only see one side of our Moon. (Why? the time the moon takes to rotate around its axis is the same as the time the moon takes to rotate around the earth).
2) Scientists are still
not sure about whether the moon has originated from the Earth or if it came from the outer space. the most recent hypothesis is the
Giant Impact.
3)
The Moon is slowly getting away from us every year by 3.8 cm. billions of years ago the Moon was much closer and thus the earth rotation around its axis was faster (example: the day was 21.9 hours 620 million years ago).
4) The Moon stabilizes the Earth rotation and by that it
stabilizes our climate. (by keeping the tilt of the earth rotation axis constant (23.4°)).
5) The Moon has
no atmosphere so the
sky will always be black on the Moon and there will not be a medium to carry out your sound waves.
6) The
dark spots on the moon are called
Maria (Latin word means seas).
7) The Moon is responsible for our
ocean tides.
