Which planets are hotter than the sun, and the hottest one is found to be 2 1000 degrees Celsius?

The universe is vast and full of surprises. Many mysterious celestial bodies have been discovered since human exploration. Even some celestial bodies shocked scientists. The mystery of the universe is far beyond human imagination. We know that the closer the galaxy is to the main star, the higher the surface temperature. Venus in the solar system is the closest planet to the sun and the planet with the highest surface temperature, reaching 480 degrees. The nearest planet is Mercury, and its surface temperature is 430 degrees. Many people may have questions. Mercury is closest to the sun. Why is it not as hot as Venus?

The main reason is that Mercury has no atmosphere, Venus has a thick layer of gas, and Venus has a layer of sulfuric acid in its atmosphere. The greenhouse effect increases the surface temperature of Venus. 480 degrees is the highest temperature in planets of the solar system, and the nutria constellation has a planet 63 light years away from the Earth. Its surface temperature is as high as 3000 degrees. Iron can be melted at such a high temperature. We know that the melting point of pure iron is only 1535 degrees, and 3000 degrees is the boiling point of pure iron. What kind of planet is this terrible surface temperature? This planet is similar to Jupiter and is also a gaseous planet. Super typhoons often erupt on the earth's surface, reaching more than 10000 km per hour, which is about five times the highest level of typhoons on the earth. It's unbelievable. Scientists named this planet HD 189733b. It has such a high temperature because it is close to the parent planet and rotates very fast. It only takes two days to orbit the star once.

Although it is close to the star, scientists are also puzzled why the surface temperature can reach such a high level. Only by understanding the substances in the atmosphere of HD 189733b can we find the answer. Scientists plan to measure substances in the atmosphere of HD 189733b with nano-radiation. However, the measurement task was not smooth and ended in failure. Why is it difficult for us to detect the substances in the atmosphere of HD 189733b? The experts who conducted the investigation explained that in order to explore the properties of the earth's atmosphere through nano-radiation, the traditional method is to radiate substances containing nano-elements into the atmosphere to make them react with substances in the atmosphere. ?

However, because the volume of HD 189733b is very close to Jupiter, it is difficult for light to reflect and propagate between HD 189733b and Jupiter. Therefore, in the atmosphere of HD 189733b, it is very difficult to obtain relevant information by using the light reflection effect. It seems that there is no way to measure the planet and understand the atmosphere for the time being. The reason why this planet has a high temperature of 3000 degrees is not only close to its parent star, but also related to the material composition of its atmosphere If it were not for the special environment inside the earth, the surface temperature would not reach 3000 degrees.
