Mars,
the red planet puzzle
the ancient Greeks called this planet that. Red Planet (Red Planet), because the star is red and ripe, brighter than any star. Once believed that "Mars" is the twin stars of the world and the creatures may have lived. The stories And many science fiction that discusses the red planet Mars (or the English name "Mars" represents the Roman god of war) is still one of the riddles of the universe. At every age, men do not abandon efforts to discover and recognize the most
basic information
or the red planet Mars. It is the only planet in the solar system has ever believed that. There is a high possibility to discover life in the past and may in the present. It was chosen for the exploration and settlement of mankind in the future. It is not surprising that many countries in the world superpowers of their spacecraft to explore and research
away from the Sun, Mars is the 4th and the 7th largest in the solar system. A diameter of about 6,794 kilometers, or 4222 miles, which is larger than half of the world. Mars has a mass of 6.42 x 10 23 kilograms, or about 1/9 of a gravitational mass of the Earth's surface, about 38% of the Earth's surface, so the weight of 60 kilograms on Earth. It weighs approximately 22.8 kg on the surface of Mars. Mars is from the Sun, about 227,940,000 kilometers, or 141,600,000 miles, a distance of about 1.5 times the distance from the Sun to Earth. The Mars is an elliptical orbit around the sun and the distance between 206.6 to 249.2 million kilometers from the sun. The average temperature on Mars is -65 degrees Celsius (-85 degrees or Barents Farmington Heights), while the actual temperature is between -140 to + 20 ° C
(or -220 to + 70 ° North Barents Heights. ) Mars has two small moons Phobos moon are meant to fear, and Deimos means terrible. The meaning of the name is consistent with the two moons of Mars. Which refers to the god of war itself. Mars has a thickness of approximately 0.7% of the Earth's atmosphere. It is enough to wind or dust storms by the atmosphere consists of Carbon Dioxide (95.3%) Nitrogen (2.7%) Argon (1.6%) Oxygen (0.15%), steam (0.03%) and other Martian surface composed. rocks that contain metals such as iron and metal powder most. As a result, when viewed from Earth, seen as red. As polar ice and frozen carbon dioxide. Previously believed Mars is a planet similar to Earth. But in fact, Mars has a much lower temperature than the dry. The atmosphere is light It can not prevent the spread of radiation from the Sun
, Mars is a planet with Earth (Terrestial planet) with a difference of altitude of the terrain than any planet. Southern Highlands of Mars is full of craters. Similarities The moon, which is very different to the Northern Hemisphere. Which is flat and younger, but with the history of the complex. There are elevation changes at the edge of the area tens of kilometers. The interior of Mars, which analyzed data collected from the surface. Expect 1.7000 km radius of a dense core surrounded by molten rock and a thin crust. Mars has a lower density compared to the other terrestrial planets. And may indicate that its core consists of iron and sulfur (iron and iron sulfide).
