The process crumpled the surface, creating lobe-shaped scarps or cliffs, some hundreds of miles long and soaring up to a mile high, as well as Mercury's " Great Valley ," which at about miles long, miles wide and 2 miles deep 1, by by 3.
Owing to its proximity to the Sun, Mercury is a difficult planet to visit. Mercury is also the smallest planet in the solar system, measuring just 3, miles wide at its equator. Space Missions to Mercury: Mariner The spacecraft orbited Mercury three times and mapped around half of the surface of Mercury.
Maximum temperature occurs when the Sun is at an angle of about 25 degrees past noon due to diurnal temperature lagat 0.
During the Mariner 10 mission it discovered evidence that Mercury has a magnetic field. This means that to an observer at Mercury's poles, the center of the Sun never rises more than 2.
