33. The Longest Valley In The Solar System Is On Mars

Not content with having the largest mountain and volcano we're currently aware of, Mars has gone ahead and claimed the largest valley as well. Here's a twist, though - we have n idea how it got there.

Valles Marineris, as it's known, was first spotted in 1971 by Mariner 9. Putting the Grand Canyon to shame, it's 2,500 miles long - about as long as the entire United States of America! We are yet to locate any evidence of tectonic plate activity in Mars, which leaves scientists puzzled as to how the valley came to be formed; one theory is that a chain of volcanos on the other side of the planet exploded with such force that the entire crust of the planet was bent, and Valles Marineris is the resulting scar.
