Surface pressure: 92 bars Surface density: ~65. kg/m 3 Scale height: 15.9 km Total mass of atmosphere: ~4.8 x 10 20 kg Average temperature: 737 K (464 C) Diurnal temperature range: ~0 Wind speeds: 0.3 to 1.0 m/s (surface) Mean molecular weight: 43.45 Atmospheric composition (near surface, by volume): Major: 96.5% Carbon Dioxide (CO 2), 3.5% ...
Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover. At the surface it has a mean temperature of 737 K (464 °C; 867 °F) and a pressure 92 times that of Earth's at sea level.
The similarities to Earth in size and mass produce a similarity in density—5.24 grams per cubic centimetre for Venus, compared with 5.52 for Earth. They also result in a comparable surface gravity—humans standing on Venus would possess nearly 90 percent of their weight on Earth.
Earth's nearness to Venus is a matter of perspective. The planet is nearly as big around as Earth. Its diameter at its equator is about 7,521 miles (12,104 kilometers), versus 7,926 miles (12,756 kilometers) for Earth. From Earth, Venus is the brightest object in the night sky after our own Moon.
The density of Venus is 5.204 grams per cubic centimeter. Need some kind of comparison? The density of Earth is 5.515 g/cm 3. So Venus is definitely less dense than Earth. And it’s even...
Density of Venus: The second planet from our Sun, as well as the second-closest terrestrial planet, Venus has a mean density of 5.243 g/cm 3 . Again, this is very close to Earth’s own...
Like its size, its density is comparable to Earth at 5.243 grams per cubic centimeter. The volume of the planet is 223 billion cubic miles (928 billion cubic kilometers), about 86...
Venus has a mass of 4.87 × 10 24 kg, or 85% that of Earth. The mentioned similarities also give way to similar densities, Venus having a density of 5.24 grams per cubic centimeter, while Earth has 5.52. Venus is the second closest planet to the Sun, at a distance of 108.2 million km/ 67.24 mi or 0.7 AU receiving the sun’s light in 6 minutes.
The diameter of Venus is 7,521 miles or 12,104 kilometers. This is close to the 7,926 miles or 12,756 km diameter of the Earth. Venus’ mass is roughly 80 percent that of Earth’s. 95% of Earth’s density is the density of Venus.
