How long is the diameter of mars

Methane is quickly destroyed in the Martian atmosphere in a variety of ways, so discovery of substantial methane indicates that an ongoing process is releasing it.

Mars lacks any tectonic plate movement. That may allow the source of the methane to release it in plumes. The lack of plate tectonics is also the reason that the largest mountain in the Solar System was able to form. Olympus Mons, on Mars, is a shield volcano that is 27 km tall and about km across.

The absence of plate tectonics allowed a single hotspot to pour molten material onto the surface uninterrupted for millions of years.

You started out wondering what the diameter of Mars is and, now, you have several interesting facts to ponder. The length of Valles Marineris is equivalent to the length of Europe and extends across one-fifth the circumference of Mars.

By comparison, the Grand Canyon is only km mi long and nearly 2 km 1. Valles Marineris was formed due to the swelling of the Tharsis area, which caused the crust in the area of Valles Marineris to collapse. It is 10 times longer and 10 times wider than the Grand Canyon.

Mars also has sand on its surface, made up from basaltic rock, thus having a grey color. When the wind blows, dunes are created including series of parallel ridges in crater floors, also horseshoe-shaped dunes are created. Mars also has dust devils, towering vortices of wind similar to tornadoes. When the dust devils blow the red dust around on the greyish basaltic plains, they can leave behind complex and beautiful curlicues.

Mars actually has avalanches. Cliffs towering above the surface that hold different materials can be dislodged in the spring when carbon dioxide thaws, creating tremendous cascades of rock and dust. Mars has only 2 known moons named Phobos and Deimos after the horses that pulled the chariot of the god of war Mars. They are very small though, Phobos has a diameter of about 25 km or They look very much like asteroids and it is strongly believed that they have been captured by Mars gravity from the nearby asteroid belt.

Phobos orbits Mars only 6. Tides from Mars are also altering its orbit, slowly lowering Phobos closer and closer to the surface. It is believed that in a few million years Phobos will drop low enough that it will actually enter the atmosphere and impact the surface. On June 7, , NASA announced that the Curiosity rover had discovered organic compounds in sedimentary rocks dating to three billion years old, indicating that some of the building blocks for life were present.

In July , scientists reported the discovery of a sub-glacial lake on Mars, the first known stable body of water on the planet. It sits 1. Out of all the planets in the Solar System, Mars appears to have the highest change of having life forms but still the conditions are harsh enough that nothing should be able to survive there, perhaps only beneath the surface. Still, regardless of its habitability now, Mars was definitely once a planet filled with oceans and the right conditions of life.

Most people would be happy if we could only find evidence of life that may have existed on the Red Planet. Future astrobiology missions are planned, including the Mars and Rosalind Franklin rovers.

They have the mission to take soil samples and return them to Earth for further analysis. There are many plans for Mars, including terraforming and sending people on it, but it remains to be seen, hopes are high and missions continue. Scientists have found tiny traces of Martian atmosphere within meteorites violently ejected from Mars, then orbiting the solar system amongst galactic debris for millions of years, before crash landing on Earth.

In different cultures, Mars represents masculinity, youth and its symbol is used as the symbol for the male gender.

Mars is Mars has a radius of 3. Mars has a volume of 1. Mars has a density of 3. The Moon will be shining at a magnitude of Both sky objects will be positioned in the constellation Libra.

You can observe the lunar occultation of Mars with binoculars. Unfortunately, this celestial event will only be visible from parts of Australia. This means that a person who weighs 80 kg lbs on our planet would weigh only 30 kg 66 lbs on Mars. Although it would be much easier for humans to walk on Mars, such low gravity can have other not-so-pleasant effects on hypothetical Mars colonists — like causing muscle deterioration and osteoporosis.

The predominant color of the Martian surface is red. Other colors on Mars include golden, brown, and tan. Overall, Mars is a very cold place.

As of October , there are six rovers on the Red Planet. Mars can boast the largest volcano in the entire Solar System — Olympus Mons. With a height of 21 km, it stands about 2. In 50 million years, Phobos will either crash into Mars or disintegrate to form a ring around the Red Planet. Billions of years ago, Mars looked very similar to the Earth. However, eventually, the Red Planet lost most of its atmosphere and dried up. During the late 19th and early 20th centuries, many astronomers observed a network of canals on the Martian surface.

Some believed them to be irrigation canals constructed by an alien civilization. However, it turned out to be an optical illusion. We wish you clear skies and happy observations!
