The similarities between the moon and the earth are quite diverse. Perhaps the existence of this equation is often not fully realized.
Earth and moon are like lovebirds that cannot be separated. The two are always in touch with each other.
You need to know that the moon has an important role for Earth. The Moon is Earth’s only natural satellite.
Different from planet others have many satellites, but Earth has only one natural satellite, the moon.
As a satellite, the moon moves around the earth at an average speed of up to 1 km per second. So, in one round it takes 27.3 days.
The time of rotation of the moon is called the orbital period or sidereal period. From the motion of the moon around the earth, it can provide various benefits.
But did you know that these two things have something in common that we often don’t realize? What is this equation? Check out the following reviews.
Learn the Equations of the Moon and the Earth
The Moon is a satellite of the Earth that has existed for thousands of years in the Solar System. The influence of the moon on Earth is quite significant, especially in terms of gravity and the tides that occur.

The Moon is also the largest natural satellite of the Solar System. This corresponds to the size of the planet it orbits. The shape of the moon’s orbit about the sun is not purely round, but tends to be oval.
With the erratic shape of its orbit and its rotational motion or revolution about the Earth, scientists predict that the moon has shifted its distance from Earth.
Although between the moon and Earth it turns out to have some similarities. These equations include:
Same Round As A Ball
Sometimes we find the shape of the moon changing. Sometimes it looks perfectly round, semi-circle, crescent-shaped, it doesn’t even look like it at all. Initially, the shape of the moon was round like a ball.
Likewise, the earth and other planets also have almost the same shape, namely round. Although the Earth is not completely round, this can be proven by the existence of gravity which always points to the center of mass.

Gravity will exert pressure on the material more evenly from all directions towards the center and form a ball. When the Earth cools and becomes solid, it will form a round ball.
When the Earth does not rotate, it will form a planet with a perfect sphere. Scientists also mention that something that is perfectly spherical in all directions will become like a ball.
Has Mass and Gravity
Earth and moon are celestial bodies that have the same mass. A US space agency noted that the mass of the Earth is about 5.97×10^24 or 5.97 times 10 to the power of 24 kilograms.
While the mass of the moon is 7.35 x 10^22 or 7.35 times 10 to 22 kilograms.
In addition, the Earth and the moon are celestial bodies that both have gravity. The moon’s gravity causes the tides.
Whereas earth’s gravity serves to attract the atmosphere and hold it back. Thus, all living things can breathe well.

Being in One Solar System
What Earth and Moon have in common is that they are both in the Solar System. As we know that the Solar System is a system of interactions of various types of celestial bodies.
It consists of the sun as its center and other celestial bodies that revolve around it such as planets.
Besides planets, other celestial bodies that are also in the Solar System are the moon, other satellites, comets, asteroids, meteoroids, and so on.
Equally Rotating, Growing, and Centered on the Sun.
The sun has the greatest mass and gravity when compared to other stars. Thus, the sun can make the planets and other celestial bodies move around their orbits.
This also applies to Earth and the moon which also orbits the sun. So this is one of the similarities between the Earth and the Moon. In other words, the sun is the center of Solar system.
The next similarity between the moon and the earth is that they both rotate and evolve. Earth rotates on its axis and revolves around the sun.
While the moon rotates on its axis and revolves around its planet (Earth). By knowing some similarities between the Earth and the Moon that we may rarely realize, it is hoped that it can increase our insight and knowledge. (R10 / HR-Online / Editor-Ndu)
