Human beings are intelligent beings, and it took us hundreds of years to finally go out of the earth to explore the mysteries of the universe. Only after human beings left the earth did they discover that the universe is vast and infinite, and human beings are very small compared to the universe. Hundreds of years ago, humans believed that the earth was the center of the universe, and the moon and stars in the sky revolved around the earth.

But with the development of human technology, we found that this is not the case. In the solar system, the sun is the center, the earth revolves around the sun, and the earth is more than 1 million times smaller than the sun. We know that the solar system is a small galaxy among the many galaxies in the Milky Way, and the universe is composed of countless galaxies.

From the point of view from which the earth was conceived, the solar system is also our home. However, we still know too little about this homeland, and there are still many mysteries that have not been solved by us.

Uniqueness of the solar system

The planets in the solar system are arranged in size, and the ones closest to the sun are the inner planets, that is, Mercury and Venus, as well as Earth and Mars. The most important constituents of such planets are silicate rocks. Next in line are the gaseous planets with relatively large masses and sizes, such as Jupiter and Saturn, as well as Uranus and Neptune. Because these stars contain the most components are gaseous substances.

The solid rocks in the solar system are in a corresponding order, followed by the gaseous planets. The main reason is that in the Kuiper belt, all dwarf planets have corresponding movement rules.

Retrograde sun

This is a phenomenon unique to Mercury. According to Kepler's three laws of planets, the closer a planet is to its star, the faster its orbital speed. When Mercury is at perihelion, its revolution speed is faster than its rotation speed, and when it is at aphelion, its revolution speed is slower than its rotation speed. So watching a sunset on Mercury sometimes sees the sun halfway down, then rise again, and then set again.

Great Red Spot

The Great Red Spot is a spectacle of the solar system that we are very familiar with. It is located in the southern hemisphere of Jupiter. Today the Great Red Spot is a little smaller than it was at its peak, but it's still quite large. What is even more terrifying is that this cyclone has been raging for more than 350 years and has not stopped.

Venus in flames

Researchers have observed that Venus was actually the most habitable 3 billion years ago. Although Venus is said to be the twin of Earth by many people, there is obviously a big difference between the two. Venus is similar in size, weight, rock type, etc. to Earth, but the difference is quite obvious. Venus has a thick atmosphere, while Earth's atmosphere is relatively thin. Venus is hot, and Earth's temperature is reasonable. Earth has a magnetic field, while Venus has a relatively weak magnetic field. In general, Earth is suitable for human habitation, while Venus is completely unsuitable.

With the passage of time, the temperature of Venus has now reached more than 500 degrees, and the air pressure in it has already exceeded 90 times that of the earth. This also means that what appears on Venus is an ocean of fire. The more convincing answer is that the impact of the asteroid caused the magnetic field of Venus to be lost and gradually disappeared. The ozone layer was then blown away by the solar wind.
