The temperature on Mars is a cold mystery

The God of War Mars in the ancient Roman pantheon was considered the father of the Roman people, the guardian of fields and domestic animals, then the patron of equestrian competitions. His name is the fourth planet from the Sun. Probably, the blood-red view of the planet caused the first observers to associate with war and death. Even the satellites of the planet received the corresponding names - Phobos ("fear") and Deimos ("horror").

The Red Mystery

Each planet has its own riddles, but none of them so intrigued Earthlings as Mars. Unexplained for a long time there was an unusual red view of the planet, it was interesting and what temperature on Mars, and not on it depends on its color. Today every schoolboy knows that the abundant content of iron minerals in the Martian soil gives it such a color. And in the past there were some questions that the most inquiring minds of the earthlings were looking for.

Cold Planet

By its age this planet is the same as Earth and other neighbors in the solar system. Scientists suggest that her birth took place 4.6 billion years ago. And although the history of the development of the planet is not yet clear, much has already been established, including the temperature on Mars.

More recently, a large thickness of the ice deposit at the poles in both hemispheres was discovered. This is an indication that there was once a liquid water on the planet. And the temperature of Mars may have been completely different. Many scientists suggest that if there is ice on the surface, then the water must remain in the rocks. And the presence of water is a confirmation of the fact that there used to be a life here.

It is established that the atmosphere of the planet has a density of 100 times less than the earth's. But despite this, clouds and wind form in the layers of the Martian atmosphere. Above the surface sometimes raging huge dust storms.

What temperature on Mars is already known, and thanks to the data obtained, we can conclude that the red neighbor is much colder than on Earth. Near the poles in winter, the lowest temperature was recorded , -125 degrees Celsius, and the highest in the summer reaches +20 degrees in the equator.

What is different from Earth

Between the planets there are many differences, some of them quite significant. Mars in size is much inferior to Earth, twice. And the planet is located much further from the Sun: the distance to the star is almost 1.5 times farther than our planet.

Since the mass of the planet is relatively small, the gravity on it is almost three times less than on the Earth. On Mars, as well as on our planet, there are different seasons, but their duration is almost twice as large.

In contrast to the Earth, Mars, whose air temperature on the average is -30 ...- 40 ° С, has a highly rarefied atmosphere. Its composition is dominated by carbon dioxide, which suggests that there is no greenhouse effect. Therefore, throughout the day, the temperature on Mars at the surface varies significantly. For example, at noon it can be -18 ° C, and in the evening it is -63 ° C. At night, the temperature was fixed at the equator and 100 degrees below zero.
