Moon
Moon is the only satellite of the Earth. According to astronomers, both the earth and the moon were created separately, but at the same time, which later became cold and planets and satellites. From rocks and soil samples imposed by astronauts from the Moon, it was known that the moon is as old as the Earth and it was about 460 million years ago.
The distance between Earth and Moon is 384,400 km is. Its surface area is 37940,000 square kilometers. is. On the surface of the moon are numerous piles. These fortifications are due to the fall of meteorites. The mountains of the moon are high, but their plates are muddy. There are no peaks, nor straight steep slopes. There is neither water nor moon on the moon, so there is no life there either. The day goes out suddenly and in the same way the night is also sudden. There is no sound because there is no air. Gravity of the Moon is 1/6 of the Earth’s gravity. If you bounce a meter on the earth, then the surface of the Moon will bounce at 6.05 meters. Similarly, weight is also affected. The weight of any object on the moon’s surface becomes the sixth part. The temperature drops to 120 ° C in the day and to -160 ° C in the night. On July 20, 1969, American astronaut Neil Armstrong and Edwin Aldrin conducted many studies by reaching the moon.
Diameter– Approximately one fourth of the Earth’s diameter (3776 km.)
Gravitational Force- 1/6 Part of Earth
The period of rotation of the moon around the earth is 27 days, 7 hours, 43 minutes.
The time spent in determining the light of the moon to reach the earth is 3 seconds.
The sun shines on the same surface of the Moon, its second surface remains in the dark. It completes one revolution of the earth in 27.3 days. The moon does not have its own light. The sun radiates on it, so we can see it, the moon is not always the same. We do not see him at all when he changes his size throughout the month. When the Sun is on the other side of the Earth, then we see the whole moon.
When the earth comes in between the Moon and the Sun then the Moon is formed. Such a situation happens only on the full moon day. That is, the moon eclipse occurs only to a full moon.
Tides in the oceans come due to the movement in the moon. Although the Sun is also responsible for it, but the Moon has more impact on the tides due to the nearness of the Sun than the Sun.
The distance of the Moon with the help of laser rays is 3,84,00 km Measured in which only 15 cm Has the error.
The largest black diamond on the moon is 232 km. Whose depth is 365.7 meters. The collected rocks have aluminum, iron, magnesium etc. There are also silicates.
Moon’s diameter is 3476 km is. The moon is 81.3 times heavier than the Earth’s tuna, and the Moon is 49 times larger in volume.
