  2. Atmosphere of Venus - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Venus

    The early Earth during the Hadean eon is believed by most scientists to have had a Venus-like atmosphere, with roughly 100 bar of CO 2 and a surface temperature of 230 °C, and possibly even sulfuric acid clouds, until about 4.0 billion years ago, by which time plate tectonics were in full force and together with the early water oceans, removed ...

  3. Geology of Venus - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Venus

    The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.

  4. Surface features of Venus - Wikipedia

    en.wikipedia.org/wiki/Surface_features_of_Venus

    The surface of Venus contains almost 1000 impact craters. However, unlike some planets in our system, Venus' thick atmosphere creates a strong shield that decelerates, flattens, and can fracture incoming projectiles. The Venusian surface is devoid of small craters (≤30–50 km in size) because of the effect the atmosphere has on small bodies.

  5. List of geological features on Venus - Wikipedia

    It is sometimes called Earth's "sister planet" due to their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). The surface of Venus is covered by a dense atmosphere and presents clear evidence of former violent volcanic activity.

    The Venusian diameter of about 7,500 miles (12,000 km) is just a tad smaller than Earth's 7,900 miles (12,750 km). "Venus and Earth are often called sister planets because of their similarities in ...

    Venus is similar in size and distance from the sun when compared with Earth, and some researchers believe the planet might have even had an Earth-like climate at some point.

    Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.

  9. Venus - Wikipedia

    en.wikipedia.org/wiki/Venus

    Venus's atmosphere is rich in primordial noble gases compared to that of Earth. [95] This enrichment indicates an early divergence from Earth in evolution. An unusually large comet impact [96] or accretion of a more massive primary atmosphere from solar nebula [97] have been proposed to explain the enrichment. However, the atmosphere is ...
