The total surface are of the Earth is 510,065,284.702 km² or 51,006,528,500 hectares.  The land surface area is 148,939,063.133 km² or 14,893,906,300 hectares

Mars is not hot. It's pretty cold. The average surface temperature is -8°C. In best conditions, it takes about a month to get there. The trip would be on a spaceship and you'd be PARTYING!

Mars has only a quarter the surface area of the Earth and only one-tenth the mass, though its surface area is approximately equal to that of the Earth's dry land because Mars lacks oceans.

Dave_Stark\n23 seconds ago\n\n\n \n The average distance from Mars to the Sun is 1.52369 astronomical units. One astronomical unit (AU, the average distance from the Sun to the Earth) is 1.49597870E11 meters.\n\nConverting those numbers, then, means that Mars is:\n\n1.52369 * 1.4959787E11 meters = 2.27941E11 meters, or, converting into English units:\n\n141,635,833 miles (on average -- remember that the orbits of the planets around the sun are not circular, but elliptical)

think of a pyramid as half of a cube, with the base sides equal to Sqrt(2) times the side of the cube.  a whole cube would have twice the volume and be 60cm^3, So, the dimensions would be 60^(1/3) or 3.91cm sides and 3.91*2^(1/2) or 5.54cm base lengths.

A good answer to this question would quite lengthy.   I strongly recommend Robert Zubrin's book "The Case For Mars".  It covers the subject in great detail, but can be understood by nearly anyone with a basic education in science.

not sure about the mass and size, i always thought mars is bigger than earth? just are you sure your questions are sensible coz as far as i remember, we on earth are still trying to figure out how to get there.

There are polar caps on Mars that vary with the season. These are composed of ice, and dry ice (solid CO2). The Martian atmosphere is about 3% water vapor, which is the most water vapor that it can hold at its temperature and pressure, so it has a high relative humidity. We believe that Mars has permafrost under the surface. There appear to be runoff channels from water in some places on the Martian surface. \n\nIf there ever was a civilization on Mars, they did not leave much in the way of clues or ruins, or at least they have not been found yet, and I suspect they will not be.

In October, 2005, Mars came within 42-million miles of Earth\n\nIn 2003 it came the closest it has in the last 50,000 years -- 35-million miles\n\nYour weatherman who said it would be as large as the Moon must have been smokin' some wacky tabacky :)

Even though Mars is said to be the most Earth like plant in our solar system. For instance.\n1. Day length (Earth 23h 56min to Mars 24h 37min)\n2. Distance from the sun (Earth 1AU, Mars 1.381AU - 1666AU)\n\nThere are many difference between Earth and Mars that would effect life.\n1. there is no breathable air on mars (made up of 95.3% CO2 and only 0.15% Oxygen). \n2. the gravity of mars in only 38% of Earth, and most likely resulting in muscle deterioration of earth based species (Use it or loss it).\n3. There is also a difference in planet temperature (Mars has be known to have temperatures around -55 degrees Celsius)\n\nThese points among others mean that life on Mars (if possible) would require a different approach then living on Earth.

Scientists are interested in mars because it is the most earth-like planet in the solar system.It has mountains and valleys,polar ice caps,and dry river beds.Scientists are particularly keen to discern whether water,a key ingredient for life,exists or existed in the past on Mars.

Mars is larger than Mercury in size, but smaller than the Earth. It orbits the Sun at a distance 50% farther away from the Sun than the Earth. Mean density of Mars is 3930 kilogram per cubic meter.

This site has up-to-date release-quality photos (ie. not raw data, just the images that are good enough for a regular person to want to look at) from the Mars Exploration Rovers (Spirit and Opportunity):\n\nhttp://www.jpl.nasa.gov/missions/mer/

Mars takes 688 Earth days to orbit the Sun once.  This is a bit less than two Earth years (730 days), or not quite 6% less.  So about ten orbits, depending on when in 1987 you want to count from..

Olympus Mons on Mars.  Not sure of the exact height but close to 27 kilometres (about 88,600 feet)!   This is only in "our" solar system, but hey, thats got to be one of the tallest.

All of the features of Mars are named. Check out the Google Maps site at http://www.google.com/mars/ for the Mars map, and you can do a simple search on google for "Mars maps" and get plenty of hits.
