Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet. (An interesting side note: the Roman god Mars was a god of agriculture before becoming associated with the Greek Ares; those in favor of colonizing and terraforming Mars may prefer this symbolism.) The name of the month March derives from Mars.

Mars (IPA: /ˈmɑɹz/ (GenAm); /ˈmɑːz/ (RP)) is the fourth planet from the Sun. The planet is named after Mars, the Roman god of war. Mars is also known as “The Red Planet” due to its reddish appearance as seen from Earth. The prefix areo-, from the Greek god of war, Ares, refers to Mars in the same way geo- refers to Earth.

Mars has two moons, Phobos and Deimos, which are small and oddly shaped. These may be captured asteroids similar to 5261 Eureka, a Mars Trojan asteroid. Mars can be seen from Earth with the naked eye. Its apparent magnitude reaches −2.9, a brightness surpassed only by Venus, the Moon, and the Sun. For much of the year, Jupiter may appear brighter to the naked eye than Mars.

Until the first flyby of Mars by Mariner 4 in 1965, it was hoped, both within and outside scientific circles, especially in the popular media and literary circles, that Mars had ample liquid water. This was based on observations of periodic variations in light and dark patches, particularly in the polar latitudes, and long dark striations that could perhaps even be irrigation channels of liquid water.

These straight line features were shown not to exist and explained as optical illusions. Still, of all the planets in our solar system other than Earth, Mars is the most likely to harbor liquid water, and perhaps life. Mars' rotational period and seasonal cycles are also similar to those of the Earth. It has the highest mountain in the solar system, Olympus Mons, the largest canyon in the solar system, Valles Marineris, and polar ice caps. Geological evidence suggests that Mars previously had large-scale water coverage, while observations also indicate small geyser-like water flows in recent years.[1]

Mars is currently host to four orbiting spacecraft: Mars Global Surveyor (non-functional), Mars Odyssey, Mars Express, and Mars Reconnaissance Orbiter. This is more than any planet except Earth. It is also home to the two Mars Exploration Rovers (Spirit and Opportunity). Recent evidence from NASA's Mars Global Surveyor, shows evidence that southern polar "ice" cap has been receding.[2]


The red/orange appearance of Mars' surface is caused by iron(III) oxide (rust).[3]

Mars is the fourth planet from the Sun and the seventh largest:

orbit: 227,940,000 km (1.52 AU) from Sun
diameter: 6,794 km
mass: 6.4219e23 kg
Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet.

its called the red planet. the surface temp. is about 100 degree celcius. human life over there is not possible but the surroundings over there might be suitable for some plants as there is water vapour content. has two satellites the phobos and deimos which are said to have been the part of asteroids because of its irregular shape

THERE IS VERY NEGLIGIBLE AMT OF ATMOSPHERE ON MARS.
IT MAINLY CONTAINS CARBON DI OXIDE,ARGON& NITROGEN.
THE POLES OF MARS R COVERED WITH DRY ICE.ACCORDING TO THE INFORMATION PROVIDED BY PATH FINDER MISSION IN 1997, THERE WAS FLOWING WATER ON MARS.BUT AT PRESENT THE PROBABILITY OF LIFE ON MARS IS NEGLIGIBLE.IT HAS 2 MOONS NAMELY- PHOBOS & DEMOS.IT IS REDDISH IN COLOUR.

I don't think its kosher to cut and paste a lot of junk and then post it here as a reply to a question.

Instead, lets thoughtfully compose a response.

And links should go under "Know your source?" space.

The red/orange appearance of Mars' surface is caused by iron(III) oxide (rust).[3]

Physical characteristics
Mars has half the radius of the Earth and only one-tenth the mass, being less dense, but its surface area is only slightly less than the total area of Earth's dry land.[4] While Mars is larger and more massive than Mercury, Mercury has slightly stronger gravity at the surface, due to its much higher density
Geology
The surface of Mars is thought to be primarily composed of basalt, based upon the Martian meteorite collection and orbital observations. There is some evidence that a portion of the Martian surface might be more silica-rich than typical basalt, perhaps similar to andesitic stones on Earth, though these observations may also be explained by silica glass. Much of the surface is deeply covered by iron(III) oxide dust as fine as talcum powder.[5]

Although Mars has no intrinsic magnetic field, observations have revealed that parts of the planet's crust have been magnetized. This magnetization has been compared to alternating bands found on the ocean floors of Earth. One theory, published in 1999 and reexamined in October 2005 with the help of the Mars Global Surveyor, is that these bands are evidence of the past operation of plate tectonics on Mars.[7] Polar wandering could also explain this paleomagnetism.

Current models of the planet's interior infer a core region approximately 1,480 km in radius, consisting primarily of iron with about 15-17% sulfur. This iron sulfide core is partially fluid, with twice the concentration of light elements that exists at the Earth's core. The core is surrounded by a silicate mantle that formed many of the tectonic and volcanic features on the planet, but now appears to be inactive. The average thickness of the planet's crust is about 50 km, and it is no thicker than 125 km.[8]

The geological history of Mars is split into three broad epochs:

Noachian epoch (named after Noachis Terra): Formation of the oldest extant surfaces of Mars, 3.8 billion years ago to 3.5 billion years ago. Noachian age surfaces are scarred by many large impact craters. The Tharsis bulge is thought to have formed during this period, with extensive flooding by liquid water late in the epoch.
Hesperian epoch (named after Hesperia Planum): 3.5 billion years ago to 1.8 billion years ago. The Hesperian epoch is marked by the formation of extensive lava plains.
Amazonian epoch (named after Amazonis Planitia): 1.8 billion years ago to present. Amazonian regions have few meteorite impact craters but are otherwise quite varied. Olympus Mons formed during this period along with lava flows elsewhere on Mars.
An alternative series of classifications, based on data from OMEGA Visible and Infrared Mineralogical Mapping Spectrometer on board the Mars Express orbiter has also been put forward.
