Some people say that the sun, the moon and the earth are a mysterious combination! Because the diameter of the sun is about 400 times the diameter of the moon, and the distance between the sun and the earth is about 400 times the distance between the earth and the moon, the moon in the sky is as big as the sun from the ground.

The diameter of the Pexels sun is 139.2 km and the diameter of the moon is 3446 km. The average distance between the sun and the earth is 150 million kilometers, and the average distance between the earth and the moon is 38,000 kilometers. Judging from the data, this is indeed a very coincidence.

The astronomer explained that it was an astronomical coincidence!

It is precisely because of this wonderful coincidence that we can see the wonderful sight of a total solar eclipse on Earth. During the total solar eclipse, the moon completely obscured the light of the sun, and the whole earth dimmed.

No special combination such as the sun, moon and earth has been found in the solar system. And the mass of the moon accounts for 1.23% of the mass of the earth, the earth, such a small rocky planet, can actually have moons as large as the moon, which is also unique in the solar system.

Tuyuan Pexels for this magical phenomenon, some people think that this is not a coincidence, because this coincidence in its view is so incredible, it is difficult not to doubt that it is designed.

For this designer, some people think it is a god, others think it is an alien. But under different opinions are guesses, not only there is no substantive evidence, but also poor logic.

Many people have refuted this conjecture with conspiracy theories, but many people still believe it. This is actually understandable, after all, everyone's cognitive level is different. When we were in primary school, we were told that the earth is a sphere, and we gave you a lot of examples, but do you know? There are still some people in the world who think the earth is flat.

Pexels: in fact, it is a coincidence that the moon in the sky looks as big as the sun, and it is a coincidence that only exists in this period of time. This coincidence is an interlude in hundreds of millions of years!

According to scientists, the moon was formed after a large celestial body collided with the primitive earth at the beginning of the solar system. At the beginning of the moon's birth, it was very close to the earth, only tens of thousands of kilometers, and the earth rotated very fast at that time. With the gradual distance of the moon, the moon is now 380000 kilometers away from the earth, and the speed of the earth's rotation is much slower than at the beginning of its birth, with a rotation period of about 24 hours.

In the course of more than 4.5 billion years of life on the earth, the earth's orbit has hardly changed much. So it can be known that more than a billion years ago, the moon in the earth's sky looked bigger than the sun. At that time, there was no such coincidence between the sun, the moon and the earth.

The source Pexels actually makes all this happen by inertia and gravity, and the dominant force that produces this wonderful combination is the laws of physics.

All kinds of celestial bodies in the universe have been moving ceaselessly, and the relative position and state of motion will also change with time, which is not permanent. For example, Polaris, as we know it, is not a constant star in the sky, and it will change with time. In tens of thousands of years, the shape of the Big Dipper will change significantly due to the motion of distant stars, and eventually the shape of the Big Dipper will become fragmented.
