Which planet in the universe is the scariest?

Let's talk to you about some terrible planets in the universe that are not suitable for human migration.

First of all, vampire stars

In western mythology, vampires are monsters who need to feed on other people's blood. Only in this way can they stay young. In the universe, a star will do the same thing. It is called "Vampire Star" and its scientific name is "Blue Discrete Star". Although blue discrete stars are generally old, they look brighter and more beautiful than other stars. The secret is that it will absorb hydrogen fuel from nearby stars, thus further increasing its volume.

Second, HD- 189733B (blue gaseous planet)

This is a blue gaseous planet. One of its characteristics is that the wind speed on the planet reaches 7000 kilometers per hour. In contrast, in the standard atmospheric pressure environment, the speed of sound propagation is 1224 kilometers per hour, which means that the wind speed here is 7 times faster than the speed of sound, but this is not the worst. This gaseous planet has a dense atmosphere, so there are often heavy rains. Because there are a lot of silicates in the clouds, the raindrops falling from the sky of this planet are not water droplets, but melted glass fragments. These glass particles are mixed in strong winds that are 7 times faster than the speed of sound and 30 times faster than hurricanes, enough to kill any animal we know.

Third, Jupiter

Even in the solar system, there are many planets that are difficult for people to set foot on, and the gaseous planet Jupiter is one of them. Contrary to the literal meaning, the gaseous planet does not mean that it is completely composed of gas, but because it is surrounded by a lot of hydrogen and helium, it is difficult for people to define where its surface is. Even if it can land on Jupiter, it can't live without sunlight, oxygen and great pressure. In addition, there are often hurricanes on Jupiter, which are twice the size of the whole earth. In addition, there is the strongest aurora known in the solar system, which is hundreds of times more powerful than the earth.

Four. HD- 13 1399AB

In 20 16, scientists discovered a very strange planet in Sagittarius (hd- 13 1399AB). It revolves around three suns at a time, and its rotation orbit is very long. It takes 550 years for the earth to rotate once, and the rotation speed is also slow, resulting in no day on the earth.

5.JG- 12 12B (Ocean Planet)

We have known since childhood that 70% of the earth is water, but in fact, the weight of water only accounts for about 0.005% of the total weight of the earth. At a distance of 40 light years from the earth, the weight of water on a planet accounts for 10% of the total, its radius is 2.5 times that of the earth, and its total weight is 6.5 times that of the earth. It is estimated that the ocean depth here can reach hundreds of thousands of meters. For comparison, it is about10000m deep. Under such water pressure, even the deep-sea creatures on earth have evolved very difficultly. So it is conceivable that if there is life in the ocean on this planet, what kind of monster would it be?

Six, lich star (PSR- 1257.438+02)

In old English, the word "lich" means undead, and the name of the lich star fits this definition very well, because it is a pulsar, that is, the product of an explosion before the evolution of the star.

Although according to the definition of planetary extinction, the Lich Star is actually dead, but it is still leaking radiation to its surroundings, and the amount of radiation is very terrible. For example, we all know that the sun also emits radiation. Although only 2.2 billion of this radiation reaches the earth, which is unbearable in the hottest climate, the radiation of pulsars is millions of times higher than that of the sun, and everything around them will be completely melted.

In the ancient history of the universe, the life of the earth is only a moment, but at this moment, incredible natural things, stories and customs in different cultures, and eye-opening science and technology have appeared, which constitute our irreplaceable home-the earth.
