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 is notable for having the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.
Venus in real colors, processed from clear and blue filtered Mariner 10 images. Observations of the planet Venus include those in antiquity, telescopic observations, and from visiting spacecraft. Spacecraft have performed various flybys, orbits, and landings on Venus, including balloon probes that floated in the atmosphere of Venus.
The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990–1994 Magellan mission, is centered at 180 degrees east longitude. The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus. Within the Solar System, it is the one nearest to Earth and ...
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.
The atmosphere of Venus is the very dense layer of gasses surrounding the planet Venus. 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 and hotter than that of Earth; the temperature at the surface is 740 K (467 °C, 872 °F), and the ...
Using the Pioneer Venus Large Probe data, the Mogul-led team published in 2021 a “compelling case for phosphine deep in the cloud layer (of Venus),” Mogul confirmed in an email.
Venus, the second planet from the Sun, is classified as a terrestrial planet. 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 ...
The possibility of life on Venus is a subject of interest in astrobiology due to Venus ' proximity and similarities to Earth. To date, no definitive evidence has been found of past or present life there. In the early 1960s, studies conducted via spacecraft demonstrated that the current Venusian environment is extreme compared to Earth's.
