Mars(The red planet)

The mass of mars compared to earth

At just 0.38 of the Earth standard, a person who weighs 100 kg on Earth would weigh only 38 kg on Mars. This difference in surface gravity is due to a number of factors – mass, density, and radius being the foremost.

How big is mars compared to earth

Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets. Almost 70% of Earth's surface is covered by liquid water.

How long does it take mars to orbit the sun

Mars revolves or orbits around the Sun once every 1.88 Earth years, or once every 686.93 Earth days. Mars travels at an average speed of 53,979 miles per hour or 86,871 kilometers per hour in its orbit around the Sun.

How long it takes to rotate once

We call the rotational period of Earth a "day". Mars takes just a little longer to rotate, at 24 hours, 37 minutes. The Moon is much slower than either Earth or Mars. It takes over 655 hours for the Moon to turn just once on its axis--that's more than 27 days

Atmosphiric information

The atmosphere of Mars is the layer of gases surrounding Mars. It is composed mostly of carbon dioxide. The atmospheric pressure on the Martian surface averages 600 pascals (0.087 psi; 6.0 mbar), about 0.6% of Earth's mean sea level pressure of 101.3 kilopascals (14.69 psi; 1.013 bar).

Temperature information

The small, barren planet also has a thin atmosphere that is 95 percent carbon dioxide. Mars's atmosphere is about 100 times thinner than Earth's. Without a "thermal blanket," Mars can't retain any heat energy. On average, the temperature on Mars is about minus 80 degrees F (minus 60 degrees C).

The moons of Mars

Mars has two small moons: Phobos and Deimos. Phobos (fear) and Deimos (panic) were named after the horses that pulled the chariot of the Greek war god Ares, the counterpart to the Roman war god Mars. Both Phobos and Deimos were discovered in 1877 by American astronomer Asaph Hall.

Why i chose this planet

Be ouse i feel that we can move there. Many crafts have visited there

How many space crafts have visited mars

Four rovers have landed on mars so far with all succesfull voyages. They all happend within 1997-2012. The first rover to land on mars landed July 6, 1997, the last one to land landed in Aug. 5, 2012

Fun facts about mars

Mars is the fourth planet from the Sun and is the second smallest planet in the solar system. Named after the Roman god of war, Mars is also often described as the “Red Planet” due to its reddish appearance. Mars is a terrestrial planet with a thin atmosphere composed primarily of carbon dioxide.
