god of war Mars in the ancient Roman pantheon was considered the father of the Roman people, protector of the fields and domestic animals, and then the patron of horse competitions.Its named after the fourth planet from the sun.Perhaps the blood-red appearance of the planet caused the first observer association with war and death.Even the satellites of the planet received the appropriate name - Phobos ("fear") and Deimos ("terror").
Red mystery
Each planet has its mysteries, but none of them have not intrigued earthlings as Mars.Inexplicably long remained an unusual view of the red planet, and it seemed interesting, what the temperature on Mars, and this depends on whether its color.It is now every schoolchild knows that plenty of content in the Martian soil iron minerals giving it a color.And in the past there were some questions that were looking for answers to the most inquisitive minds of earthlings.
Cold planet
At his age, this is the same planet as the Earth and the rest of the neighbors on the solar system.Scientists theorize that her birth happened 4.6 billion years ago.Although in the history of the world is not all found, much has already been set, including the what the temperature on Mars.
relatively recently been discovered a thick deposits of ice at the poles in both hemispheres.This is evidence that the planet was once liquid water existed.And the temperature of Mars may have been completely different.Many scientists believe that if there is ice on the surface, the water must be preserved in rocks.And the presence of water is a confirmation of the fact that there was once life.
established that the atmosphere of the planet has a density of 100 times less than the Earth's.But despite this, in the layers of the Martian atmosphere to form clouds and wind.Above the surface of the hugest sometimes raging dust storms.
What temperature on Mars is already known, and thanks to the data obtained, we can conclude that on the red neighbor is much colder than Earth.In the area of the poles in winter it was recorded the lowest temperature of -125 degrees Celsius, and the highest in summer reaches 20 degrees to the equator.
What is different from the Earth
between planets there are many differences, some of them quite substantial.Mars is much inferior to the size of the Earth twice.And the planet is much farther from the sun: the distance to the brightness of nearly 1.5 times more than that of our planet.
Since the mass of the planet is relatively small, and the force of gravity on it is almost three times less than on Earth.On Mars, as well as on our planet, there are different seasons, but their duration is almost twice as much.
Unlike Earth, Mars, the temperature is an average of -30 ...- 40 ° C, has a highly rarefied atmosphere.Its composition is dominated by carbon dioxide, which implies the absence of the greenhouse effect.Therefore, during the day the temperature on the surface of Mars have changed substantially.For example, at noon, it can be -18 ° C, and in the evening - is -63 ° C night temperatures were fixed at the equator and 100 degrees below zero.
