Mars is the fourth planet in our solar system.  It was discovered by pioneer astronomer and lens-crafter Hans Smickel in 1710.  “For almost a century following this discovery, astronomers dismissed the planet as a transient piece of stellar ice and speculated that it would be completely melted by cosmic rays sometime early in the nineteenth century. This hypothesis, obviously, did not prove correct.”“Today, Mars is recognized as not only the most fascinating planet  in our entire galaxy--the "Galaxy 500," as it is known by scientists.  Mars has an interesting climate.  The planet is now known to get as cold as thirty degrees below zero and to be the site of frequent snowstorms, with snowfalls in northern regions of the planet often averaging eighty inches per Martian winter--a season that lasts the equivalent of two earth years.” The southern polar regions, an area of the planet where surface temperatures often soar to a back-blistering 120 degrees Fahrenheit.

What sort of information are you looking for?


If general information, Mars is the fourth planet from the sun—the next out from Earth. The Martian day is just longer than Earth's—24 hours and about another half hour—so you could adapt easily. You'd weigh about a third what you would here, but twice what you would on the moon. There's little water and only a thin atmosphere. Mars is close enough to Earth that humans have long thought about visiting it, even colonizing it. It became even more attractive after Venus's atmosphere was discovered to be intensely hot and dense.

Mars is the fourth planet from the sun and one of the Terrestrial planets. Mars is just like Earth but smaller, drier, and colder. Mars is also known as the Red Planet because of its red dirt. The moons that orbit Mars are called Phobos and Deimos.  Mars is the owner of the biggest volcano in the solar system, Olympus Mons. It takes Mars 687 Earth days to fully orbit the sun.
