It is sometimes called Earth's "sister planet" due to their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). The surface of Venus is covered by a dense atmosphere and presents clear evidence of former violent volcanic activity.
The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.
Venus to scale among the Inner Solar System planetary-mass objects, arranged by the order of their orbits outward from the Sun (from left: Mercury, Venus, Earth, the Moon, Mars and Ceres) Venus is one of the four terrestrial planets in the Solar System, meaning that it is a rocky body like Earth.
The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) [1] that preserves geologic structures for long periods of time.
The mapping of Venus refers to the process and results of human description of the geological features of the planet Venus. It involves surface radar images of Venus, construction of geological maps , and the identification of stratigraphic units , volumes of rock with a similar age.
The surface of Venus has been divided into 8 quadrangles at the 1:10,000,000 map scale, [1] or 62 quadrangles at the 1:5,000,000 map scale. [2] 1:10,000,000 map scale

Features on the planet Venus are named for women and goddesses. Colles are small hills or knobs, named after sea goddesses. Coronae are oval features of uncertain origin, named for fertility and earth goddesses. Planitiae, low plains, are mythological heroines. Tholi, small dome-like hills, are named for (miscellaneous) goddesses.
