So far we know the moon because of its beautiful light at night. The moon is the celestial body closest to the earth. These celestial bodies can also be seen very clearly with the naked eye from the earth.
Have we known the moon? Here are the facts about the Moon
• There is no such thing as a dark side of the Moon.
All sides of the Moon get the same amount of sunlight. The concept of the dark side of the Moon arises because we can only see one side of the Moon. This happens because the Moon takes exactly 27.3 days to complete one revolution around the Earth and exactly 27.3 days to complete one rotation on its own axis. Therefore, only one side of the Moon is visible to us. The only way to see the other side of the Moon is to see it from a spacecraft.
• Gravity on the moon is much less than Earth
Earth has a gravity of 9.8m/s². Meanwhile, the gravity on the moon is much smaller, at 1.62m/s². The gravity on the moon is smaller and weaker due to its smaller size compared to the earth. the earth has a diameter of about 12,742 km while the moon has a diameter of about 3,474 km, which is 1/4 of the size of the earth.
It is because of this lower gravity that our weight will 'shrink' on the moon. Thus, our weight will be 16.5 percent of our normal body weight on earth.
• The weather on the moon is very different from the weather on earth
Although the moon is a satellite of the earth, the weather on the moon is very much different from the weather on earth. The surface temperature of the moon varies greatly. The temperature can reach 127 degrees Celsius when exposed to the sun, and to -153 degrees Celsius if you don't get sunlight. So it can be very hot or very cold.
• Not round
The moon is not round. The moon is shaped like an egg. The center of mass of the moon is not at the geometric center of the Moon, however, its center is about 2 km from the geometric center.
• The moon is the fifth largest satellite in the solar system
Another interesting fact is that the moon is the fifth largest satellite in the solar system. In the first place, there is Ganymede, a satellite that orbits and orbits the planet Jupiter. Ganymede has a diameter of 5,262 km. Followed in second place is Titan, a satellite of the planet Saturn which has a diameter of about 5,150 km.
In third position is Callisto, which is the second largest satellite of the planet Jupiter. Callisto has a diameter of 4,821 km, followed by Io, which is also a satellite of the planet Jupiter. Its size is slightly larger than the moon, which is 3,643 km. And in fifth position is the moon which has a diameter of 3,475 km, explained the World Atlas page.
• Stealing Earth's energy
Each year, the moon steals some of Earth's rotational energy, and uses it to propel itself about 1.6 inches (4 centimeters) higher in its orbit.
Researchers say that when it formed about 4.6 billion years ago, the moon was about 14,000 miles (22,530 kilometers) from Earth. It is now more than 280 thousand miles, or 450 thousand kilometers away. Meanwhile, the Earth's rotation rate is slowing, which causes the days to get longer and longer.
Looking at the interesting moon facts above, it turns out that the moon is really really needed by the earth. Hope it is useful!
