Which of the eight planets has the highest temperature?

Venus is the hottest of the eight planets.

Venus, one of the eight planets in the solar system, is the second planet in the distance sequence from the sun, with a distance of 0.725 astronomical unit. It is the closest planet to the earth (Mars is sometimes closer). The brightness in the night sky is second only to the moon, and Venus will reach its maximum brightness before sunrise or after sunset. The surface temperature of Venus is 464℃, which is the highest among the eight planets.

Extended data:

Venus is the planet with the largest number of volcanoes in the solar system. More than 1600 large volcanoes and volcanic landforms have been discovered. In addition, there are countless small volcanoes, and no one has counted their numbers. The estimated total is over 654.38+million, even 1 million.

Venus and the earth have a lot in common. They are similar in size and volume. Venus is also the closest planet to the earth in the solar system, and is also surrounded by clouds and a thick atmosphere. Like the earth, Venus's surface age is very young, about 500 million years.

There is no water on the surface of Venus and there is no water in the air. The main component of its cloud is sulfuric acid, which is much higher than the height of the earth cloud. Due to the high atmospheric pressure, the wind speed on Venus is relatively slow. In other words, the surface of Venus is neither affected by wind nor washed by rain. Therefore, the volcanic characteristics of Venus can obviously be maintained for a long time.
