Venus: The Atmosphere, Climate, Surface, Interior and Near-Space Environment of an Earth-Like PlanetVenusThis is a review of current knowledge about Earth's nearest planetary neighbour and near twin, Venus. Such knowledge has recently been extended by the European Venus Express and the Japanese ...
Venus - Atmosphere, Orbit, Surface: Since Galileo’s discovery of Venus’s phases, the planet has been studied in detail, using Earth-based telescopes, radar, and other instruments. Over the centuries telescopic observers, including Gian Domenico Cassini
These missions have provided valuable insights into Venus's atmosphere, surface, and composition. Key Points: Venus is the second planet from the Sun and the sixth largest in the Solar System. It has a dense atmosphere composed primarily of carbon dioxide, resulting in a powerful greenhouse ...

Venus is the secondplanetfrom theSun, and the closest toEarth’s orbital path. It is a rocky planet, and its size, structure, and chemical composition is similar to that of Earth. For this reason, Venus is often called Earth’s twin. ...
Venus is the second planet from the Sun, which orbits around the Sun every 224 Earth days. It has the longest rotational period (243 days) of any planet in the Solar System, and rotates in the opposite direction to most other planets. It does not have an
proximity to the sun, and composition, Venus is often referred to as Earth's "sister planet". With a mass of 4.8676×1024 kg, a surface area of 4.60 x 108 km², and a volume of 9.28×1011 km3, Venus is 81.5% as massive as Earth, and has 90% of itssurface areaand 86.6% of...
Third, very little sunlight reaches the planet’s surface. About 60 percent of the sunlight that hits Venus is reflected back into space by the thick clouds that fill the atmosphere, which means that only 40 percent of the sunlight can get through the clouds. Below these clouds is a dense...
Terrestrial planet Venus has a similar size, mass, and bulk composition to Earth. Previous studies proposed that local plume-induced subduction existed on both early Earth and Venus, and this prototype subduction might initiate plate tectonics on Earth but not on Venus. In this study, we simulate...
Due to these similarities Venus is considered as ‘twin-planet’ of Earth. However, Venus also possesses many dissimilarities with Earth such as lack of any intrinsic magnetic field2,3, high surface pressure (~93 bar), atmospheric composition (predominantly CO2), and high surface temperatures1...
