Venus

Also known as ♀, Planet Venus

Venus is the second planet from the Sun. Similar in size and mass to Earth, Venus has no liquid water, and its atmosphere is far thicker and denser than that of any other rocky body in the Solar System. The atmosphere is composed mostly of carbon dioxide and has a thick cloud layer of sulfuric acid that spans the whole planet. At the mean surface level, the atmosphere reaches a temperature of and a pressure 92 times greater than Earth's at sea level, turning the lowest layer of the atmosphere into a supercritical fluid. From Earth, Venus is visible as a star-like point of light, appearing brig

OverviewAI-generated

Venus is an inner and inferior planet of the Solar System that orbits the Sun. It possesses an atmosphere and is characterized by its orbit and the potential for life on its surface. The planet has a radius of 6051.8 and a mass of 4867.5. Its highest point is Skadi Mons.

Venus has an orbital eccentricity of 0.0068 and a flattening of 0. The semi-major axis of its orbit is 108208930, with an orbital inclination of 3.39471. The argument of periapsis is 131.60246718, and the longitude of the ascending node is 76.67984255. Its orbital period is 19414148, and its synodic period is 583.92. The albedo is 0.689.

The demonym for Venus is Venusian, Venerian, Venusano, or Vénusien. It is described by sources including the Brockhaus and Efron Encyclopedic Dictionary, Gujin Tushu Jicheng, The Nuttall Encyclopædia, and the Encyclopædia Britannica 11th edition.

The orbits of Venus and Earth make the two planets approach each other in synodic periods of 1.6 years. In the course of this, Venus comes closer to Earth than any other planet. In interplanetary spaceflight from Earth, Venus is frequently used as a waypoint for gravity assists, offering a faster and more economical route. Venus has no moons and a very slow retrograde rotation about its axis, a result of competing forces of solar tidal locking and differential heating of Venus's massive atmosphere. As a result, a Venusian day is 116.75 Earth days long, about half a Venusian solar year, which is 224.7 Earth days long.
