Mars 3D Postcard by Authentic Cards

Mars is the fourth planet from the Sun in the Solar System and the nearest neighbor to Earth. Due to its orange and glutton appearance it was named after the Roman god of war. The name "red planet" is often used, too. The red color can be explained by iron(III)-oxide-dust (rust), that is scattering within the atmosphere. The two small moons Phobos and Deimos are orbiting the Mars and are shown here also truly-3D.
