Which planet is bigger - Mars or Earth? The planets of the solar system and their dimensions

People have always been interested in unexplored spacesspace. Studies of other planets attracted many scientific figures, and the common man is interested in the question of what is there in space? First of all, scientists pay attention to the planets of the solar system. Since they are closest to the Earth and easier to learn. Particularly actively exploring the mysterious red planet - Mars. Let's find out which planet is bigger - Mars or Earth, and try to understand how the red heavenly body attracts us so much.

Brief description of the planets of the solar system. Their sizes

From the Earth all the planets of our system seem to ussmall luminous dots, which are hard to see with the naked eye. It differs from all Mars - it seems to us larger than other celestial bodies, and sometimes even without telescopic equipment one can see its orange light.which planet is more mars or earth

Which planet is bigger: Mars or Earth? We see Mars so well, because its dimensions are huge, or is it just closer to us? Let's figure this out. For this purpose, let us consider successively the dimensions of all the planets belonging to the solar system. They were divided into two groups.

Earth group of planets

Mercury is the smallest planet. In addition, it is closest to the rest of the Sun. Its diameter is 4878 km.

Venus is a planet next to the remoteness from the Sun and closest to the Earth. The temperature of its surface reaches +5000 degrees Celsius. The diameter of Venus is 12,103 km.

The earth is different in that it has an atmosphere and water reserves, which gave birth to life. Its size is slightly larger than Venus and is 12 765 km.

Mars is the fourth planet from the sun. Mars is smaller than the Earth and has a diameter at the equator of 6786 km. Its atmosphere is almost 96% composed of carbon dioxide. Mars has a more elongated orbit of rotation than the Earth.Mars less land

The giant planets

Jupiter is the largest of the Solar planetssystem. Its diameter is 143,000 km. It consists of gas, which is in a vortex motion. Jupiter revolves around its axis very quickly, about 10 Earth clock, it makes a full turn. It is surrounded by 16 satellites.

Saturn - a planet that can be justifiedcall unique. Its structure has the smallest density. More Saturn is famous for its rings, the width of which is 115,000 km, and the thickness is 5 km. It is the second largest planet in the solar system. Its size is 120,000 km.

Uranus is unusual in that it can be seen with a telescope in a blue-green color. This planet also consists of gases that travel at a speed of 600 km / h. The diameter is slightly more than 51 000 km.

Neptune consists of a mixture of gases, most of which is methane. It is because of this that the planet has acquired a blue color. The surface of Neptune is shrouded in clouds of ammonia and water. The size of the planet is 49,528 km.

The most remote planet from the Sun is Pluto, it does not belong to any of the groups of planets in the solar system. Its diameter is half that of Mercury and is 2320 km.

Characteristic of the planet Mars. Features of the Red Planet and comparison of its size with the size of the Earth

So we looked at the dimensions of all the planetsThe solar system. Now you can answer the question of which planet is bigger - Mars or Earth. This can be helped by a simple comparison of the parameters of the diameter of the planets. Dimensions of Mars and the Earth are two times different. The Red Planet is almost half as large as our Earth.description of Mars

Mars is a very interesting spaceobject for study. The planet's mass is 11% of the Earth's mass. The temperature on its surface varies throughout the day from +270 to -700 degrees C. The sharp difference is due to the fact that the atmosphere of Mars is not so dense and consists primarily of carbon dioxide.

Description of Mars begins with an emphasis on hissaturated red color. I wonder what caused this? The answer is simple - the composition of the soil, rich in iron oxides, and the increased concentration of carbon dioxide in its atmosphere. For such a specific color, ancient people called the planet bloody and gave it a name in honor of the Roman god of war - Ares.

The surface of the planet is mostly deserted, but there are also dark areas, the nature of which has not yet been studied. The northern hemisphere of Mars is a plain, and the southern hemisphere is slightly raised from the middle level and is dotted with craters.

Many do not know, but on Mars is the highest mountain in the entire solar system - Olympus. Its height from the bottom to the top is 21 km. The width of this hill is 500 km.

Is life on Mars possible?

All the works of astronomical scientists are aimed at,to find signs of life in space. In order to study Mars on the presence of living cells and organisms on its surface, this planet was visited by rovers several times.the size of Mars and the earth

Numerous expeditions have already proved that earlierThere was water on the Red planet. It is still there, only in the form of ice, and it is hidden under a thin layer of stone soil. The presence of water is also confirmed by photographs, which clearly show the channels of the Martian rivers.

Many scientists want to prove that a person can adapt to life on Mars. In the proof of this theory, the following facts are cited:

  1. Almost the same speed of movement of Mars and the Earth.
  2. Similarity of gravitational fields.
  3. Carbon dioxide can be used to produce vital oxygen.

Perhaps in the future development of technologywill allow us to easily make interplanetary travel and even settle on Mars. But first of all, humanity must preserve and protect its native planet - the Earth, so that it never has to wonder which planet is bigger - Mars or Earth, and whether the red planet will be able to receive all those who want to migrate.
