The troposphere on Venus contains 99% of the atmosphere by mass. 90% of the atmosphere of Venus is within 28 km (17.5 mi) of the surface; by comparison, 90% of the atmosphere of Earth is within 16 km (10 mi) of the surface. At a height of 50 km (31 mi) the atmospheric pressure is approximately equal to that at the surface of Earth. [34]
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.
Terrestrial planets have a compact, rocky surfaces, and Venus, Earth, and Mars each also has an atmosphere. Their size, radius, and density are all similar. Terrestrial planets have numerous similarities to dwarf planets (objects like Pluto), which also have a solid surface, but are primarily composed of icy materials.
While this may be exciting news, Venus is still far from being a hospitable place for Earth organisms. Scientists have detected oxygen in the atmosphere of Venus Skip to main content
SAR images provide the highest resolution data set. Microwave radiation is used to penetrate the thick atmosphere and map the surface of Venus. The SAR images are black and white images, which show the surface features using the intensity of radar return (echo), either due to surface roughness or orientation. [7]
Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.

The initial observations of Venus' super rotation were Earth-based. Modern GCM models and observations are often enhanced by looking at past ancient climates. In a model where Venus is assumed to have an atmospheric mass similar to Earth, SS-AS circulation could have dominated over super-rotation in an ancient thinner atmosphere. [2]
