Venus is about 7,521 miles (12,104 km) in diameter. This is about 95% of the diameter of the Earth. Venus is the closest to Earth in size and mass of any of the other planets. Mass and gravity Venus’ mass is about 4.87 x 1024kg. The gravity on Venus is 91% of the gravity ...
Category A type of Volcano (Venus) Description Centers of volcanic activity between 20 and 100 km in diameter (Head et al. 1992 ). Subtypes Based on summit morphology, López ( 2011 ) distinguished Shield Volcanoes (Fig. 1e ), tholi (domical features) (Fig. 1c ), flat-topped volcanoes...
Astronomy.the planet second in order from the sun, having an equatorial diameter of 7,521 miles (12,104 km), a mean distance from the sun of 67.2 million miles (108.2 million km), a period of revolution of 224.68 days, and no moons. It is the most brilliant planet in the solar syst...

TheEarthand Venus are very similar in size with only a 638 km difference in diameter and Venus having 81.5% of the Earth’s mass. Both also have a central core, a molten mantle and a crust. The same side of Venus always faces the Earth when at their closest. ...
Venus (金星)is known as the earth’s "twin" because the two planets are so like each other in size. The diameter of Venus is about 7, 520 miles (12,100 km. ), smaller than that of the earth. No other planet comes closer to the earth than Venus. At its nearest approach it is ...
The wide angle imager has a modified achromatic Cooke-triplet lens which is 30 mm in diameter and a 12 position filter wheel with two clear filters centered at 750 nm, one with a 100 nm width, the other at 600 nm. The ten color filters are centered at 415 nm (40 nm width), 480 ...
Despite hosting over 1,000 meteor impact craters, none of Venus’ craters are smaller than 1.25 miles (2 km) in diameter. Smaller meteorites disintegrate in the planet’s thick atmosphere before reaching the surface. Venus’ largest crater, Mead, spans 174 miles (280 km) and is surrounded by...
The preservation of Venus' surface is also responsible for its impact craters, which are impeccably preserved. Almost a thousand craters exist, which are evenly distributed across the surface and range from 3 km to 280 km in diameter. No craters smaller than 3 km exist because of the effect ...
Coronae generally range from 100 to 600 km in diameter with a median of about 200 km ( Ivanov and Basilevsky, 1990 ), although a few coronae over 1000 km have been identified. The ring of ridges and grooves and the surrounding moat are usually tens of kilometers wide. Although ...
