MARS... quite possible

First ... assume an average diameter (or radius) for the planet.\n\nThe average radius normally given is 3963.1 miles (6378 km).\n\nCircumference of a circle = 2 * pi * r = pi * d\n\nCircumference = (2) * (3.14159) * (3963.1) = 24900.9 miles\n... which is approximately 40074 km.

Here are some quick facts:\n\nhttp://www.sir-ray.com/ Enter the site, click astronomy then click on Space Dimensions & Planetary Facts (this site is excellent)\nhttp://www.dustbunny.com/afk/planets/\nhttp://www.kidzone.ws/planets/index.htm\nhttp://nssdc.gsfc.nasa.gov/planetary/planetfact.html\n\nThese sites should be everything that you need~the first site should do it but the other three have little bits of information that might be useful~

Silica fume has a average size distribution from 0,3 to 0,05 microns (or less) with a specific surface area from 15 to 200 m2/g.\n\nFor more information see the web site of degussa.

"The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km)"\nThe Earth is the fifth largest planet of the solar system. The reason why earth is in a spherical shape, is because of the gravitational pull. The number that appeared most often in my sources was 12,756 km. There are actually two diameters of Earths: equatorial and polar. One of my sources stated that the equatorial diameter is 40 kilometers wider than the polar diameter. The Earth is not a perfect sphere because of a bulge in the equator. Most of the current knowledge of the Earth has been collected in three methods, through satellites, telescopes and outer space exploration.

10? Good lord. People who ask for a huge number of obscure facts are so greedy. \n\nYou know you do have search engines on the internet? Ever hear of them?\n\nI will give you a couple.\n\nThe Olympus Mons volcano on Mars is the tallest in the solar system (as tall as everest) and is as big as the entire Hawaiin island chain.\n\nThere are signs of water erosion on the surface. \n\nThe large rock "face" that was previously observed is just weathered rocks when seen from another angle.

Print out the following site and put it together. There are ones for mars at NCAA site. \nBuckminster Fuller had several different ones. One had the continents as one big island, one had one unified ocean.\nNotice when a plane travels from say, LA to Japan, it first travels to Alaska. That is the shortest distance. This would be an arc on a flat map.

http://hypertextbook.com/facts/2001/DanielChen.shtml\n\nEarth has a surface area of 196,940,400 square miles, slightly less than a perfect ball with a diameter of 7913.5 miles (which is the mean diameter of the Earth - see "Prove it" under 103).\n\nhttp://pages.prodigy.net/jhonig/bignum/qland2.html

Ten. A new planet has been discovered that is approximately the same size as Pluto. It has not yet been formally named. Check http://www.nasa.gov/vision/universe/solarsystem/newplanet-072905-images.html for more info:)

Olympus Mons is on Mars and is the highest known mountain in the solar system.  The central edifice stands 27 kilometres (88,600 feet) high over its base (about three times the height of Mount Everest above sea level and three times the height of Mauna Loa above its base); it reaches 25 km (15 miles) above the mean surface level of Mars, since it stands in a 2 km (1.2 mile)-deep depression. It is 540 km (335 miles) in width, flanked by steep cliffs, and has a caldera that is 85 km (53 miles) long, 60 km (37 miles) wide, and up to 3 km (1.8 miles) deep with six overlapping pit craters. Its outer edge is defined by an escarpment up to 6 km (4 miles) tall unique among the shield volcanoes of Mars. It is unlikely that it will be climbed in my lifetime and the physical challenge of climbing may so great that it will never be climbed. The mountains on earth such as Mount Everest are challenging enough for mountaineers.

Mars is smaller so it has a significantly smaller atmosphere.\nEarth has liquid water.\nMars is assumed to currently have no living organisms.\nMars has 2 moons.
