Venus's equator rotates at 6.52 km/h (4.05 mph), whereas Earth's rotates at 1,674.4 km/h (1,040.4 mph). [ note 2 ] [ 153 ] Venus's rotation period measured with Magellan spacecraft data over a 500-day period is smaller than the rotation period measured during the 16-year period between the Magellan spacecraft and Venus Express visits, with a ...
They make up a small area on Venus's global surface of around 7.2 x 10 8 km 2. [13] The lineament is the pattern of deformation, which make it a typical structural–material unit. [13] There is evidence showing the embayment of tessera by pdl's material in some tessera margins. Thus, it is possible that this unit is younger than the tessera ...
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.
Mead Crater is the largest impact crater on Venus, with a diameter of 280 km (174 miles). [1] The crater has an inner and an outer ring and a small ejecta blanket surrounding the outer ring. Mead Crater is relatively shallow (likely due to viscous relaxation [ 2 ] and infilling) and the crater floor resembles surrounding plain in morphology.
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.
The ionosphere of Venus consists of three layers: v1 between 120 and 130 km, v2 between 140 and 160 km and v3 between 200 and 250 km. [28] There may be an additional layer near 180 km. The maximum electron volume density (number of electrons in a unit of volume) of 3 × 10 11 m −3 is reached in the v2 layer near the subsolar point . [ 28 ]

524522 Zoozve (/ ˈ z uː z v eɪ / ⓘ; provisional designation 2002 VE 68) is a sub-kilometer sized asteroid and temporary quasi-satellite of Venus. [5] Discovered in 2002, it was the first such object to be discovered around a major planet in the Solar System.
