Venus or the Morning Star is the second closest planet from the sun after Mercury. This planet has a radius of 6052 km, diameter 12 104 km, and around the Sun in 225 days. Venus’s atmosphere contains 97% carbon dioxide (CO2) and 3% nitrogen, making it virtually impossible to have life. All about Planet Venus
Venus rotation direction opposite to the direction of rotation of other planets. In addition, the rotation period of Venus is longer than the period of revolution around the Sun.
The content of the atmosphere is thick with CO2 causes a very high surface temperatures due to greenhouse effect. Venus’s atmosphere and is always shrouded in thick clouds. Astrobiology expert speculated that the cloud layer of Venus specific termobakteri still can sustain life.
Venus is the second planet from the Sun, orbiting it every 224. 7 Earth days. The planet is named after Venus, the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of – 4. 6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47. 8°. Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, for which reason it has been known as the Morning Star or Evening Star.
Venus is classified as a terrestrial planet and it is sometimes called Earth ‘ s ” cohort planet ” owing to their uniform size, notability, and bulk composition. Venus is cloaked eclipse an opaque layer of highly reflective clouds of sulfuric harsh, preventing its surface from being observed from space in visible brilliant. Venus has the densest finish of all the terrestrial planets in the Solar System, consisting of largely reproduction dioxide. The atmospheric pressure at the planet ‘ s surface is 92 times that of the Earth. Venus has no carved figure rotation to lock angel back into rocks and surface meat, nor does it seem to hold bite the works elan to swallow it in biomass. Venus is believed to posses previously self-starting oceans, but these evaporated as the temperature claret owing to the runaway greenhouse outgrowth. The irrigate has most general photodissociated, and, because of the want of a lusty magnetic field, the handout hydrogen has been swept into interplanetary space by the solar wind. Venus ‘ s surface is a dry desertscape hold back lousy with partition – double rocks, periodically refreshed by volcanism. All about Planet Venus
All about Planet Venus
Venus is one of the four solar terrestrial planets, subject that, congeneric the Earth, it is a rocky body. In size and mass, it is undoubted companion to the Earth, and is regularly described as Earth ‘ s ” kissing cousin ” or ” twin “. The diameter of Venus is 12, 092 km ( sole 650 km less than the Earth ‘ s ) and its mass is 81. 5 % of the Earth ‘ s. Conditions on the Venusian surface differ unduly from those on Earth, owing to its dense spitting image dioxide mood. The mass of the semblance of Venus is 96. 5 % replica dioxide, obscure most of the remaining 3. 5 % being nitrogen
The Venusian surface was a subject of speculation until some of its secrets were stripped by gross science in the twentieth century. It was finally mapped in detail by Project Magellan in 1990–91. The ground shows evidence of extensive volcanism, and the sulfur in the atmosphere may indicate that there have been some recent eruptions.
About 80 % of the Venusian surface is covered by smooth volcanic plains, consisting of 70 % plains with wrinkle ridges and 10 % smooth or lobate plains. Two highland ” continents ” make up the rest of its surface area, one lying in the planet ‘ s northern hemisphere and the other just south of the equator. The northern continent is called Ishtar Terra, after Ishtar, the Babylonian goddess of love, and is about the size of Australia. Maxwell Montes, the highest mountain on Venus, lies on Ishtar Terra. Its peak is 11 km above the Venusian average surface elevation. The southern continent is called Aphrodite Terra, after the Greek goddess of love, and is the larger of the two highland regions at roughly the size of South America. A network of fractures and faults covers much of this area.
The absence of evidence of lava flow accompanying any of the visible caldera remains an enigma. The planet has few impact craters, demonstrating that the surface is relatively young, approximately 300–600 million years old. As well as the impact craters, mountains, and valleys commonly found on rocky planets, Venus has a number of unique surface features. Among these are flat – topped volcanic features called farra, which look somewhat like pancakes and range in size from 20–50 km across, and 100–1, 000 m high; radial, star – like fracture systems called novae; features with both radial and concentric fractures resembling spider webs, known as arachnoids; and coronae, circular rings of fractures sometimes surrounded by a depression. These features are volcanic in origin.
Most Venusian surface features are named after historical and mythological women. Exceptions are Maxwell Montes, named after James Clerk Maxwell, and highland regions Alpha Regio, Beta Regio and Ovda Regio. The former three features were named before the current system was adopted by the International Astronomical Union, the body that oversees planetary nomenclature.
The longitudes of physical features on Venus are expressed relative to its prime meridian. The original prime meridian passed through the radar – bright spot at the center of the oval feature Eve, located south of Alpha Regio. After the Venera missions were completed, the prime meridian was redefined to pass through the central peak in the crater Ariadne. All about Planet Venus
