This is the reason why Mars' atmosphere is about times thinner than Earth's. The average temperature on Mars is about minus 80 degrees Fahrenheit i. Whereas, according to the data, Earth's average temperature is This means that without a 'Thermal blanket,' Mars cannot retain any heat energy. As per reports, Mars temperature near the poles falls down to minus degrees F i.
Nevertheless, summers on Mars near the equator are better than winter as the temperature may get up to 70 degrees F i. This intrigued many astronomers as they find it astonishing to see temperatures this warm. On an average Mars day , the planet is about degrees F C - which yes, is much colder than Minnesota right now. But that's just part of the range of temperatures on the Red Planet. During winter, temperatures near the poles can get down to degrees F C.
Which is why we could really say it's colder than Mars on parts of Earth any day of the year. Those two temperatures wouldn't feel the same to the human body, because of Mars' thin atmosphere and lack of water vapor. In other words, without as many water molecules to steal your heat, it wouldn't feel as cold.
So here's the deal: Like any other planet, Mars sees a wide range of temperatures depending on the location on the planet and the time of year. Yes, it has seasons like Earth because of the tilt of its axis. It revolves around the Sun every days and rotates every Mars has two tiny satellites, named Deimos and Phobos shown below.
They are most likely small asteroids drawn into Mars' gravitational pull. Deimos and Phobos have diameters of just 7 miles and 14 miles, respectively. An interesting side note; the inner moon, Phobos, makes a revolution around Mars in slightly more than seven hours. This means since it orbits Mars faster than the planet rotates, the satellite rises in the west and sets in the east if observed from the Martian surface. Atmosphere and Weather: The Martian atmosphere is composed primarily of carbon dioxide.
However unlike Venus, the Mars atmosphere is very thin, subjecting the planet to a bombardment of cosmic rays and producing very little greenhouse effect. Mariner 4, which flew by Mars on July 14, , found that Mars has an atmospheric pressure of only 1 to 2 percent of the Earth's.
Temperatures on Mars average about degrees F. However, temperature's range from around degrees F. Various probes over the past few decades have found the surface of Mars to be rather desert like.
A fascinating panoramic view of the martian surface was taken picture below in by the Pathfinder mission. The surface is cratered, but not as much as our Moon or Mercury. The craters have probably been weather worn over the years by fierce windstorms, some of which can cover the entire planet. These windstorms are common on the red planet, lifting rust-colored dust well up into the atmosphere encircling the entire globe.
The rest of Mars has patches of green. But it is not clear what is producing this green color as it certainly is not vegetation. Evidence does exist in the terrain that water has eroded some of the soil.
No flowing water is present today, but NASA announced on March 2, that the two rovers, Spirit and Opportunity confirmed liquid water once flowed on Mars. The meteorite was dated back 4. At present, Mars' water appears to be trapped in its polar ice caps and possibly below the surface. Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away.
No precipitation falls however.
