The hottest planet in the Solar system
I’m sure many at school know that about the heavenly bodies revolve eight planets, one of which is the hottest planet in the Solar system. And does not the mercury close to the Sun. The hottest planet is Venus, which is located second from the heavenly bodies.
What is the temperature on Venus?
The hottest planet in the solar system Venus is considered for the surface temperature, which can range from 460 to 480 degrees. On average, it turns out that the temperature on this planet is 475 degrees (enough to easily melt the lead or tin). And more close to the celestial luminary mercury average temperature is only 426 degrees. Since the surface of this planet has no atmosphere, the temperature regime they are able to deviate by hundreds of degrees.
To maintain more or less the average temperature on the surface of Venus allows carbon dioxide. The dense atmosphere of the planet allows the surface temperature to be five degrees more than if the atmosphere were absent.
As was open Venus?
In ancient times people thought that this planet is two stars, which appeared morning and evening. But then it became clear that it is one planet that revolves around the heavenly bodies. When the Sun was so bright, Venus was also not very hot. It was even oceans of liquid. However, the life-giving moisture is evaporated, contributing to the greenhouse effect. This now contributes to the solar radiation and carbon dioxide. Currently, Venus is very hot due to this effect, and the heating process continues. Today everybody knows that life on the planet is not, after all, in the absence of oxygen it is impossible to live.
What does the name of the planet?
This planet was named after the Roman goddess of love. Quite interesting is the fact that it is the only planet, which he called a female name. Perhaps Venus is so named because it shines much brighter than all the planets known at that time astronomers. Translated from the Latin name «Venus» means «Evening star» or «Lucifer (Satan in Christianity).
What are the features of the planet?
The second location of the planet to the Sun Venus is quite a bit less of our planet Earth. Because of the almost identical size, density, mass and composition of these planets are even called twins. However, in these settings, the similarities end.
The hottest planet in the Solar system is located in one hundred eight million kilometers from the Sun. Around it there are no satellites. The day here lasts about 243 earth days. 225 the same day, the planet makes one revolution around heavenly bodies. The surface of Venus is characterized by a hardness, a large number of craters and volcanic landscapes. And it rotates in the opposite direction, which means that the sunrise is happening in the West and sunset in the East.
The atmosphere of Venus is very heavy and even «hellish». The pressure in it exceeds ninety times the pressure present on Earth. The surface of Venus has no liquid and due to all the high temperature, which causes the process of boiling and evaporation. Also the planet has mountain ranges and valleys, which, according to scientists, was formed when rising to the surface of burning materials, which led to deformation of the surface.
Studies of the planet
Since Venus is the hottest planet, you may think that to explore it is almost impossible. However, scientists were able to obtain information about the planet Venus researched more than forty spacecraft. Interesting pictures managed to «produce» a Soviet spacecraft, which had the same with the planet name. Apparatus «venera13» was able to stay on the planet for 127-mi minutes (this was in 1981). With it, was made color images of the surface of Venus.
All the devices that were sent to study Venus, could be on the surface no more than two hours. After this time, destroyed the probes high temperature. The idea of 98 percent of Venus ‘ surface was obtained in the nineties. But today, the planet creates a lot of interest for scientists who continue to investigate major objects in the Solar system.
