Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen, with other chemical compounds present only in trace amounts. [1] It is much denser than and almost two and a half times as hot as that of Earth ; the temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (1,350 psi), roughly the pressure found ...
Atmosphere of Venus in UV, by Pioneer Venus Orbiter in 1979. Venus' atmosphere is mostly composed of carbon dioxide. It contains minor amounts of nitrogen and other trace elements, including compounds based on hydrogen, nitrogen, sulphur, carbon, and oxygen. The atmosphere of Venus is much hotter and denser than that of Earth, though shallower.
Venus is the second planet from the Sun.It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth.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 this height, the temperature is a manageable 75 °C (348 K; 167 °F). At 5 km (3.1 mi) higher, it is a temperate 27 °C (300 K; 81 °F) (see Atmosphere of Venus § Troposphere). The atmosphere also provides the various elements required for human life and agriculture: carbon, hydrogen, oxygen, nitrogen, and sulfur. [5]
Its thick and noxious atmosphere is dominated by carbon dioxide - 96.5% - with lesser amounts of nitrogen and trace gases. In fact, with Venus getting far less scientific attention than other ...
The angular size of Earth is between 48.1″ and 6.6″ and of the Moon between 13.3″ and 1.7″, comparable to that of Venus and Mercury from Earth. Near maximum elongation (47.4°), the Earth and Moon would shine at apparent magnitudes −2.5 and +0.9, respectively.
