LEARN EVERY THING ABOUT THE PLANET VENUS

THE DEFINITION OF VENUS

Venus is the second planet from the Sun, orbiting it every 224.7 Earthdays. It has no natural satellite. It is named after the Roman goddessof love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitudeof −4.6, bright enough to cast shadows. Because Venus is an inferior planetfrom Earth, it never appears to venture far from the Sun: its elongationreaches a maximum of 47.8°.
Venus is a terrestrial planetand is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphereof the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressureat the planet's surface is 92 times that of Earth's. With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System, even though Mercuryis closer to the Sun.

Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary spaceby the solar wind.
Venus's surface is a dry desertscape interspersed with slab-like rocks and periodically refreshed by volcanism.



Facts about Venus




A day on Venus lasts longer than a year:

It takes 243 Earth days to rotate once on its axis. The planet’s orbit around the Sun takes 225 Earth days, compared to the Earth’s 365

.Venus rotates counter-clockwise:
Also known as retrograde rotation.

A possible reason might be a collision in the past with an asteroid or other object that caused the planet to alter its rotational path. It also differs from most other planets in our solar system by having no natural satellite.

PHYSICAL CHARACTERISTICS OF VENUS

Size comparison with Earth.





Venus is one of the four terrestrial planetsin the Solar System, meaning that, like Earth, it is a rocky body. In size and mass, it is similar to Earth, and is often described as Earth's "sister" or "twin". The diameter of Venus is 12,092 km (only 650 km less than Earth's) and its mass is 81.5% of Earth's. Conditions on the Venusian surface differ radically from those on Earth, owing to its dense carbon dioxide atmosphere. The mass of the atmosphere of Venus is 96.5% carbon dioxide, with most of the remaining 3.5% being nitrogen.



Geography of VENUS




The Venusian surface was a subject of speculation until some of its secrets were revealed by planetary sciencein the 20th century. It was finally mapped in detail by Project Magellanin 1990–91. The ground shows evidence of extensive volcanism, and the sulfurin the atmosphere may indicate 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.
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 lavaflow accompanying any of the visible calderaremains an enigma. The planet has few impact craters, demonstrating the surface is relatively young, approximately 300–600 million years old.
In addition to the impact craters, mountains, and valleys commonly found on rocky planets, Venus has some unique surface features. Among these are flat-topped volcanic features called " farra", which look somewhat like pancakes and range in size from 20 to 50 km across, and from 100 to 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 Regioand Ovda Regio. The latter 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.

SURFACE GEOLOGY OF VENUS

DEFINING THE SURGACE GEOLOGY OF VENUS



Much of the Venusian surface appears to have been shaped by volcanic activity. Venus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km across. The only volcanic complex of this size on Earth is the Big Islandof Hawaii. This is not because Venus is more volcanically active than Earth, but because its crust is older. Earth's oceanic crustis continually recycled by subductionat the boundaries of tectonic plates, and has an average age of about 100 million years, whereas the Venusian surface is estimated to be 300–600 million years old.

INTERNAL STRUCTURE OF VENUS

INTERNAL STRUCTURE



Without seismic data or knowledge of its moment of inertia, little direct information is available about the internal structure and geochemistryof Venus.

The similarity in size and density between Venus and Earth suggests they share a similar internal structure: a core, mantle, and crust. Like that of Earth, the Venusian core is at least partially liquid because the two planets have been cooling at about the same rate.
