Venus - Atmosphere

Click image for description Venus, the second planet from the Sun, is named after the Roman goddess Venus. A terrestrial planet, it is sometimes called Earth's "sister planet", as the two are very similar in size and bulk composition. Although all planets' orbits are elliptical, Venus's orbit is the closest to circular, with an eccentricity of less than 1%. As Venus is closer to the Sun than the Earth, it always appears in roughly the same direction from Earth as the Sun (the greatest e ...

Venus - Atmosphere. Venus has an atmosphere consisting mainly of carbon dioxide and a small amount of nitrogen, with a pressure at the surface about 90 times that of Earth (a pressure equivalent to a depth of 1 kilometer under Earth's oceans); its atmosphere is also roughly 90 times more massive than ours. This enormously CO2-rich atmosphere results in a strong greenhouse effect that raises the surface temperature more than 400 Â°C (750 Â°F) above what it would be otherwise, causing temperatu ...

Space probes in the 1960's made it pretty clear that the surface of Venus is far too hot to support life as we know it. However, the cloud cover supports fairly life-friendly conditions at higher altitudes. Some speculate that spores from Earth could hitch a ride on small passing asteroids and survive a trip to Venus's atmosphere. Recent spectrographic observations have found carbonyl sulfide in the atmosphere of Venus, a chemical that is very difficult to make via natural processes and usually associated with life. Some speculate tha ...

Venus - Mythology. The pentagram has long been associated with the planet Venus and the worship of the goddess Venus, or her equivalent. It is most likely to have originated from the observations of prehistoric astronomers. When viewed from Earth, the successive conjunctions of Venus plot the points of a pentagram around the Sun every eight years, returning to its starting point after a forty year cycle. Venus was known to ancient Babylonians around 1600 BC, and to the Mayan civilization (the Mayans develo ...

Venus is named after the Roman goddess of love, Venus. The adjective Venusian is commonly used for Venus, but the Latin adjective is Venereal, which is avoided because of its modern association with sexually transmitted diseases. Some astronomers use Cytherean, which comes from Cytherea, another name for Aphrodite in ancient Greek Mythology. Other less common adjectives include Venerean, Venerian, and Veneran. The Chinese, Korean, Japanese and Vietnamese cultures refer to the planet as the metal star, é‡‘æ˜ ...

At inferior conjunction, Venus can get closer to earth than any other planet--little more than 100 times the Moon's average distance. On December 16th, 1850, Venus reached since 1800 the lowest distance to earth with a value of 0,264138541298281 AU = 39514827 kilometres. This will be the closest approach of Venus to earth until December 16th, 2101 when Venus will ...

Venus - Orbit. Although all planets' orbits are elliptical, Venus's orbit is the closest to circular, with an eccentricity of less than 1%. As Venus is closer to the Sun than the Earth, it always appears in roughly the same direction from Earth as the Sun (the greatest elongation is 47.8°), so on Earth it can usually only be seen a few hours before sunrise or a few hours after sunset. However, when at its brightest, Venus may be seen during the daytime, making it the only heavenly body that can be seen bo ...
