These channels were probably caused by catastrophic flooding that quickly eroded the landscape.
Scientists think that most of the water on Mars is frozen in the land (as permafrost) and frozen in the polar ice caps.
It averages 141.6 million miles (227.9 million Km) from the sun.
Its orbit is very elliptical; Mars has the highest orbital eccentricity of any planet in our Solar System except Pluto.

Whether you’re in a history, literature, or science class, you’ll probably have to write a research paper at some point.It may seem daunting when you’re just starting out, but staying organized and budgeting your time can make the process a breeze.Be sure to leave plenty of time to make revisions, as editing is essential if you want to hand in your best work!Tip: Some people prefer to write the introduction first and use it to structure the rest of the paper.Mass and Gravity: Mars' mass is about 6.42 x 10.23 Kg. A year on mars takes 687 Earth days; it takes this long for Mars to orbit the sun once.Mars' Orbit: Mars is 1.524 times farther from than the sun than the Earth is.Scientists have long thought that there is no liquid water on the surface of Mars now, but recent photos Mars indicate that there might be some liquid water near the surface.The surface of Mars shows much evidence of the effects of ancient waterways upon the landscape, there are ancient, dry rivers and lakes complete with huge inflow and outflow channels.
