People are always interested in the unknown expanses of the cosmos.Research other planets attracted many scientific figures, and the common man interested in the question of what is out there in space?First of all scientists drew attention to the planets of the solar system.Since they are closer to the Earth and easier to study.Especially actively investigated the mysterious red planet - Mars.Let's find out what the planet more - Mars or Earth, and try to understand what the red celestial body so attracts us.
Brief description of the planets of the solar system.Their size
From the Earth to all the planets of our system, we seem to be small points of light that are hard to see with the naked eye.It differs from all the Mars - it seems bigger than the other celestial bodies, and sometimes even without a telescopic equipment, you can see it orange light.
What planet over Mars or Earth?We see Mars as well, because of its enormous size, or it just is closer to us?Let's see in this issue.For this series, we consider the size of the planets belonging to the solar system.They were divided into two groups.
terrestrial planets
Mercury - is the smallest planet.Moreover, it is closer to the sun all others.Its diameter of 4878 km.
Venus - a planet, the next of remoteness from the Sun and is the closest to the Earth.Its surface temperature reaches 5000 degrees Celsius.The diameter of Venus - 12103 km.
Earth is different in that it has an atmosphere and water supplies, which made it possible to support life.The size of her little more than Venus and is 12 765 km .
Mars - the fourth planet from the Sun account.Earth and Mars smaller diameter at the equator is 6786 km.Its atmosphere is almost 96% consists of carbon dioxide.Mars has a more elongated orbit of rotation than the Earth.
giant planets
Jupiter - the biggest planet of the solar system.Its diameter is 143,000 km.It consists of a gas which is in a vortex motion.Jupiter rotates on its axis very quickly, in about 10 Earth hours, he makes a complete revolution.It is surrounded by 16 satellites.
Saturn - the planet that can justifiably be called unique.Its structure has the smallest density.More Saturn is known for its rings, the width of which 115,000 km and a thickness of 5 km.It is the second largest planet of the solar system.Its size is 120,000 km.
Uranus is unusual in that a telescope can be seen in cyan.This planet is also made up of gases, which move at a speed of 600 km / h.The diameter is slightly more than 51 000 km.
Neptune is composed of a mixture of gases, most of which - methane.It is because of this planet has got blue.The surface of Neptune is shrouded in clouds of ammonia and water.The size of the planet's 49,528 km.
most distant planet from the Sun - Pluto, it does not belong to one of the groups of the planets of the solar system.Its diameter is less than twice, and Mercury is 2320 km.
features of Mars.Features of the Red Planet and compare its size with the size of the Earth
Here we examined the sizes of all the planets in the solar system.Now you can answer the question about what the planet more - Mars or Earth.This can help a simple comparison of the diameter of the planets.The size of Mars and Earth are different by half.The Red Planet is almost half that of our Earth.
Mars is a very interesting space object for study.The mass of the planet is 11% of the mass of the Earth.The temperature at its surface is changing during the day from 270 to -700 degrees C. The sharp drop due to the fact that the atmosphere of Mars is not as thick and consists mainly of carbon dioxide.
Description Mars begins with an emphasis on its rich red color.I wonder what caused that?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 bloody planet and named it after the Roman god of war - Ares.
surface of the planet largely deserted, but there are dark areas, the nature of which has not yet been studied.The northern hemisphere of Mars - the plain, and the south just raised the average level, and dotted with craters.
Many do not know, but Mars is the highest mountain in the solar system - Olympus.Its height from the bottom to the top is 21 km away.The width of this hill - 500 km.
possible life on Mars?
All the labor of scientists, astronomers focused on trying to find space in the expanse of signs of life.In order to explore Mars in the presence of living cells and organisms at the surface, often visited this planet rovers.
Numerous expeditions have proven that the previously present on the Red Planet Water.She is still there, only in the form of ice, and it's hidden under a thin layer of stone ground.The presence of water is also confirmed and pictures, which are clearly visible channel Martian rivers.
Many scientists want to prove that people can adapt to life on Mars.As proof of this theory are the following facts:
- almost the same speed of movement of Mars and Earth.
- similarity of gravitational fields.
- Carbon dioxide can be used to produce vital oxygen.
Perhaps in the future development of technologies will allow us to easily make interplanetary travel, and even settle on Mars.But first of all humankind must preserve and protect our home planet - Earth to have never had to wonder what planet more - Mars or Earth, and whether the red planet to accept all persons.
