English translation:
The Moon and Earth move around the Sun. At this moment, the moon rotates around the Earth, and the Earth around its axis at an angle of 23.5 °. Imagine that you hold the ball and rotate it with your fingers, and your palm in this moment inclined by 23.5 °. The angle of the Earth's tilt is held by the Moon. Without it would constantly change the climate on Earth, due to a change in the angle of inclination. At an angle of 50 ° Siberia will turn into the Sahara, the polar caps will melt, ocean levels rise and cities disappear under water, etc. Moon slows down the rotation of the Earth around its axis. Without it, the Earth's rotation will be faster, and the day will be about 8 hours, and in a year there will be more than 1000 days, since the time of movement around the Sun will remain unchanged.
