Mystery: How Mercury was born.

The solar system consists of nine planets, Mercury, Venus, Earth, Mars and Pluto, which are "earth-type planets" with rocks as the main components; Jupiter, Saturn, Uranus and Neptune are "Jupiter-type planets" surrounded by a large number of gases. The planet closest to the sun is Mercury. How was it born? There are two statements: First, because Mercury is closest to the sun, scientists believe that Mercury is a high-temperature area in the primitive solar system nebula, which is composed of solidified metal iron and other material rich in matter. Second, Mercury is formed by the fusion of each other's metal iron when huge primitive planets collide with each other.

Mystery 2: Why is Venus scorching?

The size of Venus is closest to the Earth, and the internal structures of the two planets may also be similar. However, according to the observations of the detection ship and radar, Venus is a scorching world, like purgatory, with a thick atmosphere of carbon dioxide on the surface. The surface temperature is as high as about 450 degrees Celsius, 30 times the temperature of the Earth. Since Venus is close to the sun, when the sun's energy rises, the water on Venus turns into gas and is released into the atmosphere. At this time, the carbon dioxide originally dissolved in the sea also accumulates in the atmosphere, causing a strong greenhouse effect and causing the surface temperature to surge.

Mystery 3: The moon is getting farther and farther away from the earth?

The moon is currently about 60 times the Earth's radius. However, due to the influence of the tidal forces between the Earth and the Moon, the moon is slowly moving away from the Earth at a speed of about 3 cm per year. On the other hand, the Earth's rotation speed is gradually slowing down. That is to say, the moon was closer to the Earth than it is now, and the Earth's rotation speed was faster than it is now. The evidence lies in the fossils of "Two Shells" discovered by scientists. The growth rate of the two Shells will change with the rise and fall of the tide, and the growth rate of the tree is formed while growing. The number and width of the stripes vary according to the size of the wetness. According to the number and width of these articles, scientists found that about 500 million years ago, the Earth had 21 hours a day and 410 days a year.

Mystery 4: Are there really Martians?

In August 1996, a research team from the NASA General Administration of Aviation and Space published research results saying that Mars once had life, and the evidence was that Mars meteorites dropped on the Antarctic continent. The research team detected organic matter in the carbonate part of the meteorites and inferred that Mars in ancient times should be like the Earth more than 3 billion years ago. At that time, the Earth already had life, so it cannot be denied that Mars had life.

Mystery 5: Why does Jupiter have a big red spot?

Earthlings have been observing the Great Red Spot in the southern hemisphere of Jupiter for more than 300 years. The Great Red Spot is about the size of two Earths. The Great Red Spot is a huge vortex formed by a highly pressed cloud that rotates counterclockwise. The reason why it appears red is because the phosphine in the lower layer of the cloud is transported to the sky and is converted into phosphorus by exposure to ultraviolet light of the sun. How does the Great Red Spot form? Scientists are not clear yet.

Mystery 6: Why does a gas satellite have a ring?

Jupiter, Saturn, Uranus and Neptune all have rings, which are different. The rings of Saturn are thin and dark, and are composed of rock particles. The rings of Saturn are large and bright, and are composed of water and ice. There are several different sayings about the causes of rings. One of them is: satellites or comets that existed in the past are destroyed by the tidal forces of the planet and split into small fragments. Some fragments enter orbits around the planet, thus forming rings.

Mystery 7: What is outside Pluto?

Some people previously advocated that there might be the tenth planet outside Pluto. In the summer of 1992, science discovered that there was a new celestial body about 250 kilometers outside the orbit of Pluto, and 41 celestial bodies with orbits of greater radius than Neptune appeared one after another. In addition, in 1950, astronomer Outter counted the orbits of periodic comets that had been observed at that time, and found that most periodic comets flew from tens of thousands of AU (astronomical units) from the sun. There might be a comet nest that encloses the solar system in the shape of a spherical shell. The entire comet nest is called "Outter Cloud".
