The largest canyon in the Solar System cuts a wide swath across the face of Mars. Named Valles Marineris, the grand canyon extends over 3,000 kilometres long, spans as much as 600 kilometres across, and is as much as 8 kilometres deep. By comparison, Earth's Grand Canyon is 800 kilometres long, 30 kilometres across, and 1.8 kilometres deep. The origin of the Valles Marineris remains unknown, although a leading hypothesis holds that it started as a crack billions of years ago as the planet cooled. The above mosaic was created from over 100 images of Mars taken by Viking Orbiters in the 1970s.
