    The whole surface area of the Moon is about 38 million square kilometers, comparable to that of the Americas. [70] [71] The Moon's mass is 1 ⁄ 81 of Earth's, [72] being the second densest among the planetary moons, and having the second highest surface gravity, after Io, at 0.1654 g and an escape velocity of 2.38 km/s (8 600 km/h; 5 300 mph).

    This list is not comprehensive, and does not list the highest places on the Moon. Clementine data show a range of about 18,100 meters from lowest to highest point on the Moon. The highest point, located on the far side of the Moon, is approximately 6500 meters higher than Mons Huygens (usually listed as the tallest mountain).

    The internal structure of the Moon was characterized in 1974 using seismic data collected by the Apollo missions of moonquakes. [11] The Moon's core has a radius of 300 km. [12] The Moon's iron core has a liquid outer layer that makes up 60% of the volume of the core, with a solid inner core. [13]
