): 96.5% — This high concentration creates a runaway greenhouse effect, trapping solar energy and making Venus the hottest planet in the Solar System. Nitrogen ( N2cap N sub 2
The atmosphere of Venus is the most massive and dense among the terrestrial planets, characterized by a crushing surface pressure of approximately (about 93 times that of Earth) and extreme surface temperatures averaging 737 K (464 °C; 867 °F) . Major Atmospheric Components Venusian (Atmospheric Mix)
): 3.5% — While a small percentage, the total mass of nitrogen on Venus is roughly four times higher than on Earth due to the sheer density of the Venusian atmosphere. Venusian (Atmospheric Mix)
