Venus is the hottest planet in the solar system: causes, temperature of the surface and atmosphere, distance to the Sun, description of the orbit, greenhouse effect.

You may have already heard that among all the planets in our system, the maximum heating is on Venus. But why Venus is the hottest planet in the solar system?

Why is Venus so hot?

Answer: the greenhouse effect. In many ways, Venus literally reflects our planet Earth. But it is sharply distinguished by the presence of a dense atmosphere. If you were on the surface, you could not withstand the pressure, exceeding the earth's 93 times.

In addition, the atmosphere itself is represented by a composition of carbon dioxide, which leads to the greenhouse effect. This is a mechanism where heat does not return to space, but accumulates on the surface.

The average temperature of Venus is 461 ° C. Moreover, it does not change between day, night and seasons. The tectonic activity of the second planet from the Sun stopped billions of years ago. Without this, carbon could not stay in the rock and is released into the atmosphere. All the oceans boiled and the water evaporated (literally blown out by the solar wind). Now you know what the temperature is on Venus and why the planet became the hottest in the system.

The hottest planet in the solar system

Surely many people from school know that eight planets revolve around the celestial body, one of which is the hottest planet in the solar system. And this is not at all Mercury, located near the Sun. The planet Venus is considered the hottest, which is located second from our heavenly body.

What is the temperature on Venus?

Venus is considered the hottest planet in the solar system for its 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 lead or tin). Moreover, on the closer to the celestial body of Mercury, the average temperature is only 426 degrees. Since there is no atmosphere on the surface of this planet, the temperature regime there can deviate by hundreds of degrees.

Carbon dioxide allows maintaining a more or less average temperature on the surface of Venus. The planet's dense atmosphere allows the surface temperature to be five hundred degrees higher than if such an atmosphere were absent.

How was Venus discovered?

In ancient times, people thought that this planet was two stars that appeared in the morning and in the evening. However, later it became clear that it is one planet revolving around our heavenly body. When the Sun was not yet so bright, Venus was not too hot either. It even had oceans of fluid present. However, the life-giving moisture evaporated, contributing to the emergence of the greenhouse effect. This is now facilitated by solar radiation and carbon dioxide. Venus is currently very overheated due to this effect, and the heating process continues. Today everyone knows that there is no life on the planet, because in the absence of oxygen it is impossible to live.

What does the name of the planet mean?

This planet was named after the ancient Roman goddess of love. The fact is quite curious. that this is the only planet that was named by a female name. Perhaps Venus was named so because it shone much brighter than all the planets known to astronomers at that time. Translated from Latin, the name "Venus" means "Evening Star" or "Lucifer" (Satan in Christianity).

What are the features of the planet?

The planet Venus, the second in position to the Sun, is quite a bit smaller than our planet Earth. Due to their almost identical size, density, mass and composition, these planets are even referred to as twins. However, with these parameters, their similarity ends.

The hottest planet in the solar system is located one hundred and eight million kilometers from the sun. There are no companions around her. A day here lasts about 243 Earth days. For 225 days of the same, the planet makes a revolution around the heavenly body. The surface of Venus is hard, craters and volcanic landscapes. It rotates in the opposite direction, from which it follows that the sunrise occurs in the west, and sets in the east.

The atmosphere of Venus is very heavy and even "hellish". The pressure on it is ninety times the pressure on Earth. The surface of Venus does not have any liquid, but is explained by the highest temperature, which causes the process of boil-off and evaporation. The planet also has mountain ranges and valleys, which, according to scientists, were formed when hot materials were raised to the surface, which led to surface deformation.

Planet exploration

Since Venus is a hot planet, it may be believed that it is almost impossible to explore. However, scientists managed to obtain information about the planet - they explored Venus over forty spacecraft. Interesting pictures were "obtained" by the Soviet spacecraft, which had the same name with the planet. The Venera13 apparatus was able to stay on the planet for 127 minutes (it was in 1981). With its help, color images of the surface of Venus were made.

All vehicles that were sent to study Venus could stay on the surface for no more than two hours. After this time, the probes were destroyed by the highest temperature. The idea of ​​98 percent of the surface of Venus was obtained in the nineties. But even today, the planet creates considerable interest for scientists who continue to study large objects in the solar system.

The planets differ in temperature, as they have different structures and distances from the Sun. As the distance from the Sun increases, the temperature on the surface of the planets, as a rule, decreases. Internal and external factors are responsible for temperature fluctuations inside the planets. The nature and composition of the atmosphere determine the amount of heat emitted and how much heat the planet can hold.

The hottest planets in the solar system:

Venus

Venus is the second and hottest among. Its temperature can reach 464º C. The high temperature is due to the dense atmosphere with thick cloud cover. Carbon dioxide makes up the bulk of Venus's atmospheric gases, acting as a blanket that prevents the planet from losing heat. Temperatures remain relatively regular with minor fluctuations throughout the year. Unlike other planets, Venus's slight elliptical tilt does not affect temperatures, allowing them to remain stable.

Mercury

Mercury is the first and smallest planet in the solar system. Despite its proximity to the Sun, Mercury is the second hottest planet. Unlike Venus, it does not have an atmosphere, so it experiences different temperatures throughout the day. Temperatures can drop to -93º C or rise to 427º C and average around 167º C. Temperatures on Mercury are directly affected by the Sun. Therefore, the side facing the star often gets hot and freezes on the shaded side. Astronomers believe that the polar regions of Mercury are never warmed by the Sun and therefore may be colder than Jupiter's cloud tops.

Coldest planets in the solar system:

Pluto

Pluto is a dwarf planet made of ice and rock. Originally considered the ninth planet, Pluto is the farthest from the sun and has the lowest temperatures, averaging around -225º C. Temperatures on Pluto depend on its proximity to the Sun: as the planet approaches a star, the temperature of the atmosphere becomes significantly warmer. The surface temperature is colder than the atmosphere due to the influence of methane, which creates temperature inversions. Pressure waves in the atmosphere lower temperatures, making them colder than expected.

Neptune

Since Pluto was disqualified as a planet, Neptune has been considered the coldest planet in the solar system with an average temperature of about -200º C. Neptune is the eighth planet in our system, composed primarily of hydrogen and helium. The planet experiences pressure and temperature fluctuations depending on altitude. Due to the large distance from the Sun, the temperature on Neptune is more dependent on the radiation inside the planet itself than on the star. Its elliptical slope of 23.4º heats the upward side, raising the temperature by about 10º C, thus avoiding the release of methane. Temperature fluctuations are also noticeable in the inner part of the planet, which occur during movement around the Sun or under the influence of internal factors such as winds and pressure changes. do not have a specific surface temperature compared to.

The average temperature of all planets in the solar system

If you are going to spend a vacation on another planet, it is important to learn about possible climatic changes :) But seriously, many people know that most of the planets in our solar system have extreme temperatures that are not suitable for a quiet life. But what exactly are the temperatures on the surface of these planets? Below I offer a small overview of the temperatures of the planets in the solar system.

Mercury

Mercury is the planet closest to the Sun, so one would assume that it is constantly glowing like an oven. However, while the temperature on Mercury can reach 427 ° C, it can also drop to the very low -173 ° C. Such a large difference in temperature of Mercury occurs because it has no atmosphere.

Venus

Venus, the second closest planet to the Sun, has the highest average temperatures of any other planet in our solar system, with temperatures regularly reaching 460 ° C. Venus is so hot because of its proximity to the Sun and its dense atmosphere. The atmosphere of Venus is composed of dense clouds containing carbon dioxide and sulfur dioxide. This creates a strong greenhouse effect that traps the sun's heat in the atmosphere and turns the planet into a furnace.

Earth

Earth is the third planet from the Sun and is still the only planet known for its ability to support life. The average temperature on Earth is 7.2 ° C, but it varies with large deviations from this indicator. The highest temperature ever recorded on Earth was 70.7 ° C in Iran. The lowest temperature was, and it reaches -91.2 ° C.

Mars

Mars is cold because, firstly, it does not have an atmosphere to maintain high temperatures, and secondly, it is located relatively far from the Sun. Since Mars has an elliptical orbit (it gets much closer to the Sun at some points in its orbit), then during the summer its temperatures can deviate by 30 ° C from normal in the northern and southern hemispheres. The minimum temperature on Mars is approximately -140 ° C, and the highest is 20 ° C.

Jupiter

Jupiter does not have any solid surface, as it is a gas giant, so it does not have any surface temperature either. At the top of Jupiter's clouds, the temperature is about -145 ° C. As you descend closer to the center of the planet, the temperature increases. At a point where atmospheric pressure is ten times that of Earth, the temperature is 21 ° C, which some scientists jokingly call "room temperature." In the core of the planet, temperatures are much higher, reaching around 24,000 ° C. For comparison, it's worth noting that Jupiter's core is hotter than the Sun's surface.

Saturn

As with Jupiter, the temperature in the upper atmosphere of Saturn remains very low - down to about -175 ° C - and increases as it approaches the center of the planet (up to 11,700 ° C at the core). Saturn actually generates heat itself. It generates 2.5 times more energy than it receives from the Sun.

Uranus

Uranus is the coldest planet with the lowest recorded temperature of -224 ° C. Although Uranus is far from the Sun, this is not the only reason for its low temperatures. All other gas giants in our solar system emit more heat from their cores than they receive from the sun. Uranus has a core with a temperature of approximately 4737 ° C, which is only one-fifth of the temperature of Jupiter's core.

Neptune

With temperatures as high as -218 ° C in Neptune's upper atmosphere, this planet is one of the coldest in our solar system. Like the gas giants, Neptune has a much hotter core, which is around 7000 ° C.

Below is a graph showing planetary temperatures in both Fahrenheit (° F) and Celsius (° C). Please note that since 2006 Pluto does not fall under the classification of planets (see.
