You see this yellow pancake every day and you know some general information about it and even some historic and scientific data, but still there are some facts about the Moon to refresh your knowledge, so here we go…
The Moon appeared as a result of a violent collision.
It is considered that the Moon is formed from the debris of the Earth and a space object of a size of Mars after their collision.
We always see one and the same side of the Moon.
The gravidity of the Earth slows down the rotation of the Moon about its axis. Rotation of the Moon got locked to its revolution.
There could be other natural satellites of the Earth.
The sister of the Moon is Cruithne, it completes a horseshoe-shaped orbit around the Earth within 770 years. It’s been near our planet for at least 5 thousand years.
The Moon does have water.
It actually does not have atmosphere, but there is some frozen water in the shadowed craters and under the soil of the Moon.
The Moon is actually not spherically-shaped.
It is egg-shaped due to the impact of the Earth’s gravity; besides, its center of mass is not geometrically in its center but about two kilometers aside from the center.
The satellite has moonquakes.
They are caused by the Earth’s gravitational impact and originate several kilometers below the surface of the Moon.
There is dancing dust on the Moon.
It hovers above the surface of the Moon – more intensively at sunrise or sunset. The particles of the dust are charged electrically or another impact may take place.
It is the Moon that causes tides on Earth.
Gravitational effect of the Moon pulls on the oceans of our planet. The highest tides appear at full or new moon.
The Moon is getting more and more remote from the Earth.
It is fed with rotational energy of the Earth and uses it to rise higher and higher in its orbit. Once it was 14 thousand miles away from the Earth, now the distance is over 280 thousand miles.
One day of the Moon equals to 29,5 days on Earth.
Imagine yourself on the Moon, these 29,5 Earth days are required for the Sun to move along the entire the sky and back.
