Mars hosts many enormous extinct volcanoes (the tallest is Olympus Mons, 21.9 km or 13.6 mi tall) and one of the largest canyons in the Solar System (Valles Marineris, 4,000 km or 2,500 mi long). Geologically , the planet is fairly active with marsquakes trembling underneath the ground, dust devils sweeping across the landscape, and cirrus clouds .
The sixteen equatorial quadrangles are the smallest, with surface areas of 4,500,000 square kilometres (1,700,000 sq mi) each, while the twelve mid-latitude quadrangles each cover 4,900,000 square kilometres (1,900,000 sq mi). The two polar quadrangles are the largest, with surface areas of 6,800,000 square kilometres (2,600,000 sq mi) each.
For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm 3, its true mass would be only 1.12 × 10 19 kg.
Mars' size difference also affects the force on its surface. If you weighed 100 lbs on Earth, you would weigh only 38 lbs on Mars . Olympus Mons is a 68,897 ft high volcano that formed billions of ...

Global study of residual Bouguer anomaly data indicates that crustal thickness of Mars varies from 5.8 km to 102 km. [5] Two major peaks at 32 km and 58 km are identified from an equal-area histogram of crustal thickness. [5] These two peaks are linked to the crustal dichotomy of Mars. [5]
Mars (35 cm (14 in) in diameter) is located at Mörby centrum, a shopping centre and Stockholm metro station in Danderyd, a suburb of Stockholm. It is 11.6 km (7.2 mi) from the Globe. It is 11.6 km (7.2 mi) from the Globe.
The following outline is provided as an overview of and topical guide to Mars: Mars – fourth planet from the Sun and the second-smallest planet in the Solar System , after Mercury . Named after the Roman god of war , it is often referred to as the " Red Planet " [ 1 ] [ 2 ] because the iron oxide prevalent on its surface gives it a reddish ...
