The dazzling beauty of planet Venus at night explains its name. Venus is one of the unique planets in our solar system, named after the well-known Roman goddess of love and beauty. Although it is very close to Earth, Venus remains so mysterious.
The Venusian surface was the top subject of speculation till some of its secrets were exposed by the planetary science in the twentieth century. Venera landers in 1982 and 1975 brought images of a surface covered in sediment and comparatively angular rocks.
The surface was eventually mapped in detail by the Magellan in 1990 to 1991. The ground reveals evidence of widespread volcanism, and the sulfur in the atmosphere may designate that there have been some new eruptions.
Nearly 80 percent of the Venusian surface is generally covered by smooth, volcanic plains, comprising of 70 percent plains with the wrinkle ridges and 10 percent lobate or smooth plains.
Two highland ‘continents’ form the rest of its surface area; one lying in the northern hemisphere of the planet and the other just south of the equator. The northern continent is known as Ishtar Terra, named after Ishtar the famous Babylonian goddess of love, and is approximately the size of Australia.
Maxwell Montes, the tallest mountain on Venus, is located on Ishtar Terra. Its peak is eleven kilometers above the Venusian standard surface elevation. The southern continent is known as Aphrodite Terra; named after the traditional Greek goddess of love, and is the bigger of the two highland locations at approximately the size of South America. A network of faults and fractures covers much of this particular area.
The absence of clear evidence of lava flows which accompanies any of the noticeable calderas remain an enigma. This planet has some impact craters, signifying that the surface is moderately young, about 300 to 600 million years old.
Venus has some distinctive surface features on top of the Impact Mountains, craters, and valleys usually found on rocky planets. Among them are flat-topped volcanic features known as “farra”, that look somehow like pancakes and range in size from 20-50 km across, and from 100-1,000 meters high; radial, and star-like fracture systems referred to as ‘novae’; features with both concentric and radial fractures like spider webs, called ‘coronae’; and ‘arachnoids’, circular rings of fractures occasionally surrounded by a definite depression. These features are also volcanic in origin.
The vast area of Venusian surface seems to have been shaped by volcanic activity. Venus features many times as several volcanoes as Earth, and it has 167 massive volcanoes which are over 100 km across.
The only volcanic complex of similar size on Earth is the Big Island of Hawaii. This isn’t since Venus is more volcanically active than our planet, but because its crust is older. Oceanic crust of the Earth is always recycled by certain subduction at the boundaries of the tectonic plates and has an average age of nearly 100 million years while the Venusian surface is approximated to be 300 to 600 million years old.
The surface is hidden under hot, poisonous air comprising mostly of carbon dioxide. The temperature, pressure, atmosphere, etc. are really unsuitable for any living organism to live.
It is considered the closest planet in size to the Earth, and it is also the nearest planet to Earth. Additionally, it has nearly same gravity to Earth, but its atmosphere is considerable different, having carbon dioxide levels over 96%.
It has a rocky surface, much like Earth, and is usually referred to as Earth’s twin. Most of the Venus’ features were named after historical and mythological women. Venus orbits the sun in every 224.65 days and is often the brightest planet to be seen at night from Earth.
Venus is known as the brightest planet in our sky at night, but are there any facts about this planet?
Interesting Facts About Venus:
1. Venus was first documented by Babylonian astronomers in the 17th century BC.
2. The surface temperatures on Venus can reach up to 470 degrees Celsius (870 degrees Fahrenheit).
3. The water bodies that existed on Venus dried up when the sun began to emit more solar energy, taking nearly 300 million years to do so.
4. The atmospheric pressure on Venus is terrific that small asteroids are often crushed when they enter its atmosphere.
5. The Russians space probe got lost in 1961 after it was sent to Venus. This was the first ever mission to Venus. The US also lost their first ever probe sent to Venus, known as Mariner 1.
6. It snows metal on planet Venus!
7. Your voice would be deeper on Venus since its dense atmosphere would certainly cause your vocal cords to vibrate more gradually.
8. Venus has more volcanoes than all other planets in the solar system, with more than 1600.
9. The clouds surrounding Venus usually consist of sulfuric acid.
10. Venus and Uranus are the only two planets which rotate from East to West.
