We all know that the Moon is a satellite of the Earth. However, a little-known fact is that it is always turned by one side to our planet. The "dark" side of the satellite causes a lot of controversy among scientists and regularly becomes the reason for the emergence of amazing theories about the existence of extraterrestrial civilizations.
On the Moon, the highest temperature reaches a mark of + 116 degrees, the smallest drops to -164 degrees. The Earth's satellite is four hundred times smaller than the Sun and four hundred times closer to our planet.
To make a turn around the Earth, the Moon takes a little more than 27 days. Our planet turns around the Sun in one year (365 days). It takes about eight and a half minutes for the light from the sun to reach us.
The number of members of the unique computer program SETI, which allows every user of the World Wide Web to take part in the search for aliens, is more than three million.
Ceres is the largest asteroid. Its radius is about 470 kilometers. It is the first asteroid that was discovered by man. They became the Italian Piazzi. This surprising event happened in January 1801.
Modern scientists divide the sky into eighty-eight sectors. They are called constellations. Interesting facts about the stars can also be attributed to the fact that the Sun moves through the Galaxy at a speed of 250 kilometers per second. If we compare with our planet, then its weight is 333 thousand times more. The sun needs two hundred million years to fly around the center of the galaxy.
This star is 30% helium, and 70% hydrogen. Its radius is approximately 218 times larger than the diameter of the Earth.

7 stars are at a distance of ten light years from the Earth. The closest to us is considered to be Proxima, which is part of the Alpha Centauri system.
The mass of our planet over the past five hundred years has increased by 1 billion tons. The reason for this is the influence of cosmic matter.
The height of the hills on Mars is 21-26 kilometers. The atmosphere there is 95% composed of carbon monoxide.
