    The North Polar Basin, more commonly known as the Borealis Basin, is a large basin in the northern hemisphere of Mars that covers 40% of the planet. [1] [2] Some scientists have postulated that the basin formed during the impact of a single, large body roughly 2% of the mass of Mars, having a diameter of about 1,900 km (1,200 miles) early in the history of Mars, around 4.5 billion years ago.

    The region is in the broader North Polar/Borealis Basin that covers most of the Northern Hemisphere of Mars. The Utopia basin is estimated to have formed around 4.3-4.1 billion years ago. [6] [7] The impactor was likely around 400–700 kilometres (250–430 mi) in diameter. [8] [9] [10] The basin was subsequently mostly filled in, resulting in ...

    Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.
