Venus: the hot and infernal volcanic planet

Venus is the second planet from the Sun. It is named after the Roman god of love and beauty. It is the only planet named after a woman. Venus may be named after the most beautiful deity in the Pantheon because it is the brightest of the five planets known to ancient astronomers.
In ancient times, Venus was generally considered to be two different stars, the evening star and the morning star, the one that first appeared at sunset and sunrise. In Latin, they are called Vesper and Lucifer respectively. In the Christian era, Lucifer or the “light bearer” was the name of Satan before the fall of Satan. However, more observations of Venus in the space age revealed a very hellish environment. This makes Venus a very difficult planet to observe closely, because spacecraft cannot survive on its surface for long.

What is Venus like?
Venus and Earth are often called twins because of their similar size, mass, density, composition, and gravity. Venus is actually only slightly smaller than our parent star, and its mass is about 80% of the Earth. The interior of
Venus consists of a metal core approximately 6,000 kilometers wide. The lava mantle of Venus is about 1,200 miles (3,000 kilometers) thick. The crust of Venus is mainly basalt, which is estimated to be 6 to 12 miles (10 to 20 kilometers) thick on average.
Venus is the hottest planet in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere will warm the earth with an uncontrolled greenhouse effect. As a result, the temperature on Venus reached 880 degrees Fahrenheit (471 degrees Celsius), enough to melt lead. These spacecraft survived only a few hours after landing on Earth and were then destroyed.

Due to the high temperature, Venus also has a hellish atmosphere, which is mainly composed of carbon dioxide and sulfuric acid clouds, with only a trace amount of water. Its atmosphere is heavier than any other planet, causing its surface pressure to be more than 90 times that of the Earth, similar to the pressure at 1,000 meters (3,300 feet) deep in the ocean.
However, it is unbelievable that according to the model of NASA Goddard Institute of Space Research and other researchers, this planet may be habitable in the early history of Venus.
The surface of Venus is extremely dry. During its evolution, the sun’s ultraviolet rays quickly evaporate water, leaving the earth in a molten state for a long time. Today there is no liquid water on its surface, because the heat generated by the ozone-filled atmosphere will cause the water to boil immediately.

About two-thirds of the surface of Venus is covered by flat, smooth plains, destroyed by thousands of volcanoes, some of which are still active today, with a range of about 0.5 to 150 miles (0.8 to 240) kilometers) wide, with lava flows sculpted into long, winding channels that are more than 3,000 miles (5,000 kilometers) long.
The six mountains make up about a third of the surface of Venus. A mountain range called Maxwell is about 540 miles (870 kilometers) long and about 7 miles (11.3 kilometers) high, making it the tallest feature on earth.

Venus also has many distinctive surface features on Earth. For example, Venus has a corona or corona, a ring structure approximately 95 to 1,300 miles (155 to 2,100 kilometers) wide. Scientists believe they form when hot matter beneath the planet’s crust rises and warps the planet’s surface. Venus also has tesserae or raised areas of tiles in which many ridges and valleys form in different directions.
Venus conditions can be said to be hellish, and Venus’s old name Lucifer seems appropriate. However, the name has no diabolical meaning. Lucifer means “bearer of light.” From the earth, Venus is brighter than any other planet or even any star in the night sky because of its high cloud reflectivity and its proximity to our planet.

It takes 243 Earth days for Venus to rotate around its axis, which is by far the slowest of all major planets. Due to this slow spin, its metal core cannot generate a magnetic field similar to that of the earth. The magnetic field of Venus is 0.000015 times the earth’s magnetic field.
When viewed from above, the direction of rotation of Venus is opposite to that of most planets. This means that on Venus, the sun appears to rise in the west and set in the east. On earth, the sun appears to rise in the east and set in the west.
The year of Venus, the time it takes to orbit the sun, is approximately 225 Earth days long. Usually this means that the number of days on Venus will be greater than a few years. However, due to the strange retrograde rotation of Venus, the time from sunrise to the next is only 117 Earth days. The last time we saw a transit of Venus before the sun was in 2012, and the next time it will be in 2117.

These are some parameters of the orbit. According to NASA data, the average distance of Venus:
The average distance from the sun: 67,237,910 miles (108,208,930 kilometers). In comparison: 0.723 times the earth. Perihelion
(the closest place to the sun): 66,782,000 miles (107,476,000 kilometers). Comparison: 0.730 times
