Here are some curiosities about Venus that demonstrate that our cosmic neighbor is one of the oddest bodies in the solar system.
Baptized by the Roman goddess of love, Venus is the neighbor of Terra and Mercury, and we enjoy every night with clear sky, being the brightest body of heaven after the moon.
Venus has fascinated humanity since ancient times and even today is a source of inspiration for artists and scholars alike.
Why do we say that? Because, more interesting than the poems describing Lucifer of the night are probably the theories of Immanuel Velikovsky , who say that Venus was originally a comet …
1. Curiosities about Venus: Say (somewhat) with Terra
If we can say that planet Earth has a sister in the solar system, then this is Venus. The mass of Venus is about 0.81% of Earth’s mass. Its size is about the same as the Earth.
Its radius is 6,052 kilometers and Earth’s distance is 6,378 kilometers. Because their sizes and masses are so similar, they mean that they have about the same density and thus the same composition.
But, in certain respects, the two planets are as different as possible. Venus has a surface temperature of nearly 482 degrees Celsius and its atmospheric pressure, composed of carbon dioxide, is 95 times higher than Earth’s atmospheric pressure.
The clouds on Venus are composed of sulfuric acid and the surface of Venus is a deserted desert. Much of the interest in Venus is related to the fact that two similar planets are, however, so different.
2. Venus is so hot because of the greenhouse effect
This is the second interesting thing on our list of curiosities about Venus. Because the atmosphere on Venus is so dense, the planet is subject to a huge greenhouse effect that warms it.
Although Venus is much closer to the Sun than the Earth, it absorbs less sunlight because of its drenched clouds. However, in the lower atmosphere and the surface there is enough sunlight.
This light is absorbed and released in the form of infrared radiation. On Earth, infrared radiation returns to space. On Venus, the carbon dioxide clouds hold the infrared radiation, warming the planet.
These curiosities about Venus show how mysterious our solar system is.
3. Curiosities about Venus: Turning “inverse”
If you looked at the solar system from above, somewhere above the northern pole of the Sun, you would see our star rotating in a direction opposite to the clockwise direction. All planets rotate in the same direction, with two exceptions.
Venus rotates clockwise on its axis. The day on Venus is very long (equivalent to 243 earth days) and is even longer than the Venus year, which has 225 earthly days. The other strangeness is the planet Uranus, which is spinning “in a wound”.
Still debating “why” Venus revolves around this. It is believed that the reason could be the effect of solar flux on the very dense atmosphere on Venus or collisions of the past with some very large bodies.
4. The atmosphere revolves faster than the planet
Venus slowly turns around its axis every 243 days, but its upper atmosphere revolves completely around the planet every four days.
Why? It is speculated that this “supertrotation”, as it is called, is related to the sun’s thermal flux, but no exact cause has been agreed upon.
5. Venus’s atmosphere could shelter life
This is the most surprising information on our list of curiosities about Venus. The superrotation of Venus was discovered by observing black strips in its atmosphere.
It is not known what these stripes are and why the supertrotation did not share them equally in the atmosphere. The strips react to ultraviolet light.
One possibility would be that these strips are proof of the existence of microbial life. The surface of Venus has a temperature of nearly 482 degrees Celsius, but at a distance of 50 to 60 kilometers above the surface of the planet, temperature and pressure are the same as the surface of the Earth.
And clouds of sulfuric acid? Microbes could be covered in molecules of eight sulphide atoms (S8), which are impermeable to sulfuric acid. S8 also absorbs ultraviolet light.
Under these conditions, life on Venus probably would not mean bipedan humanoid beings, who still speak English (as some SF films teach)
