1. The Moon has the biggest crater in our solar system. It is called the South Pole-Aitken; it is situated on the far side of the moon and is 1,550 miles (2,500 km) in diameter. The largest crater on the visible side of the Moon is called the Bailly Crater, its diameter is 183 miles.
2. The diameter of the Moon is 2,159 miles (3,475 km), almost 4x smaller than Earth’s, which is 7,926 miles (12,756 km).
3. If there were no land, but water on Earth the tidal wave would pass once around Earth in 1 day and 50 minutes. That equals the time from one moonrise tos the next.
4. The days on the Earth used to be way shorter, as before the Moon, Earth rotated faster, and as soon as the Earth got its satellite, the speed slowed down due to the gravity.
5. The astronauts from the Apollo missions 1969-72 are the only people who stepped on the Moon.
6. 6 crews from the Apollo missions brought back to Earth approximately 850 pounds (385 kg) of different samples from the Moon.
7. The Earth can fit almost 49 Moons in it.
8. 400 – this is the amount of times the Moon is smaller than the Sun and the amount of times it is closer to our planet. That’s why from the perspective of our planet both the Moon and the Sun are of the similar size.
9. The Moon is often exposed to the meteorite showers, micrometeorites or other celestial objects hitting it. It is the reason why the top layer of the Moon consists of the regolith: the mix of powdered and ground rocks creating the moon-dust.
10. An eclipse of the Sun occurs every 1-2 years, but full eclipses from the Earth are observable only once in the 100-200 years, because of the moonshadow. The eclipse itself lasts for a few minutes, and this time is not enough for us to see the eclipse.
11. From the Moon’s perspective the Earth is like 4x Moon for us, also the Earth never changes the position according to the view from the Moon’s sky.
12. Comparing to the solar eclipse, the lunar one (when the Earth is in between the Sun and the Moon) is way longer, because the shadow of the Earth is long.
