The moon is the only natural satellite of the earth, and it is the fifth largest satellite in the solar system. The moon's diameter is one-quarter of the Earth's and its mass is one-eighty of the Earth's. Relative to the planets it orbits, it is the most massive satellite and the second-densest satellite in the solar system, second only to Jupiter. one. The moon's surface is dotted with craters formed by meteorite impacts. The current distance of the moon from the earth is about 30 times the diameter of the earth.
The moon's rotation period is equal to its revolution period (called tidally locked), so the same side of the moon always faces the earth. The generation of earth's ocean tides is mainly due to the gravitational pull of the moon. Since the tidal force of the Earth's oceans is in the opposite direction to the Earth's rotation, the Earth's rotation is always subject to an extremely weak force that "brakes" the Earth's rotation. Accumulated over a long period of time, there is sufficient evidence that the Earth's rotation period is getting faster and faster. Slower, the time of a day increases extremely slowly, about 1 second in every few years; due to the reaction force of the earth, the moon slowly moves farther and farther away from the earth, about 3.8 centimeters away from the earth every year. The ratio of the size of the Moon to the Sun is similar to the ratio of distance, making its apparent size almost the same as that of the Sun. During a solar eclipse, the Moon can completely block the Sun and form a total solar eclipse.
