1. Most of the time the Moon is 238,750 mi (384,400 km) away from our planet, which makes like thirty Earth-sized planets in between.
2. There is a popular thought in the scientific field that the early Earth was hit by the blown planet of the size similar as Mars. Then the rocks from this planet were exposed to the gravity of the Earth and made a bulk and through the years created the satellite of ours.
3. Did you know that the full Moon is not standardized in size. Each full Moon is different and its size depends on the position of the Moon. When the Moon is closer to the Earth (perigee) the size is bigger, when it is farther (apogee) it is smaller.
4. Depending on the position of the Moon in relation to Earth the tides can vary in intensity. When the Moon in its apogee, the tide is normal or quite weak, as the Moon is at the bigger distance from the Earth and has not such great effect. When the Moon in at its perigee, the intensity of the tide and unpredictability of the weather increase.
5. The Moon and the Earth used to have hard times. Approximately 3-4 billion years ago, our planet and the Moon were exposed to the period of meteorite showers. If the Earth has its atmosphere that can protect from some of the meteorites, the Moon was not that lucky and this period is called lunar cataclysm.
6. The Moon’s core is very lightweight in comparison to the Earth’s one. Our core makes 30% of Earth’s mass, while the lunar one is only 2-4%.
7. The Moon is not round, as we commonly believe. It has rather of an oval shape.
8. The Moon is exposed to seismic activity, to moonquakes in particular. The reason for the moonquakes may be the gravitational pull of the Earth. Scientists say that in future if the humanity decides to build space bases on its surface, these activities can become a major problem.
9. In times of the early Moon it was located very close to the Earth - 14,000 miles (22,530 km) away. Nowadays, it is 280,000 miles (450,000 km) from our planet.
10. As there is no lunar atmosphere, the temperature there can be from less than -200° F to more than 200° F.
