Planet mars 5. The planet is named after mars the roman god of war. Mars has two relatively small compared to earths natural moons phobos about 22 km 14 mi in diameter and deimos about 12 km 75 mi in diameter which orbit close to the planet. Even though mars has only 15 of the earths volume and just over 10 of the earths mass around two thirds of the earths surface is covered in water. Phobos is gradually spiraling toward mars drawing about 6 feet 18 meters closer to the red planet each century.
These workshops were organized to bring together senior scientists young scientists postdocs and students in order to optimize the analysis and interpretation of space data and to prepare the community for the best exploitation of forthcoming missions. Mars is the fourth planet from the sun and last of the terrestrial planets and is around 227940000 km from the sun. Within 50 million years phobos will either smash into mars or break up and form. Asteroid capture is a long favored theory but their origin remains uncertain.
If you thought planet earth was the only place where life existed then you are quite mistaken. Some of the features on the surface of mars suggest that around 35 billion years ago the planet experienced huge floods. It was known to the ancient greeks as ares their god of war. Mars is designated by the symbol.
Mars orbits our sun a star. It is a periodically conspicuous reddish object in the night sky. The workshop planet mars v will be the fifth edition of a series which has taken place in the center of physics in les houches since 2003. The atmosphere on mars is very thin composed mainly of carbon dioxide 95 nitrogen 27 and argon 16 with traces of oxygen and water.
Today any water that is found on mars is in the form of water ice just below the surface in the polar regions as well as salty or briny water which flows down some of the crater walls and hillsides at various times of the year. Known as the red planet mars is characterized by its red dusty landscape. Mars and earth have approximately the same landmass. Theres life on mars though at a microbial level.
