So why do scientists study Venus? similar to our planet it seems?

The answer to this intriguing question Characteristics of Venus hidden.

Size and mass

One of the biggest reasons why they are called twins is their size and mass. very similar are. They are both almost the same size. Only Venus is slightly smaller.

The diameter of Venus is 12,104 km while it is 12,742 km from Earth. In terms of mass, it is 82 percent of the Earth. These similarities also suggest whether the formation process of the two planets took place in similar materials.

structures

Both planets have iron cores surrounded by a mantle of hot rocks. The thinnest shells cliffs and outer crust It creates. On Venus and Earth, the thin crust changes shape, and the ebb and flow of heat and pressure deep within also changes into volcanoes.

Atmosphere and greenhouse effect

Aside from its size and mass, Venus could literally become Earth’s twin, and a big factor is its atmosphere. of Venus thick and dense atmosphere, It is full of carbon dioxide and this gas surrounds the planet like a warm blanket.

In fact, this greenhouse effect is so strong that Venus The average surface temperature is 471°C!

The Earth also has a greenhouse effect, but it works much more regularly. Our atmosphere climates and protects our planet. livable makes it one. Venus, on the other hand, is a runaway version in this regard.

Orbit and distance to the sun

Another similarity is the distance between Venus and Earth from the Sun. Venus is about 108 million kilometers from the sun. Earth is 150 million kilometers away.

day and year

Another interesting difference between Venus and Earth is their speed of rotation around themselves. While the Earth revolves around its own current in 24 hours, for Venus it is one day approximately 243 Earth days It lasts until. In fact, such a slow rotation means that a year on Venus (that is, the time it takes to complete a full orbit around the Sun) is about 225 Earth days.

Also relative to Venus, Earth and other planets turns backwards. That is, the sun rises in the west and sets in the east.

life potential

The surface conditions of both are different from each other. While Earth is a lush green planet covered in oceans water on Venus It is not possible to find it. Particles about one micron long have been detected in the atmosphere of Venus, almost the size of bacteria on Earth.

Thick clouds of sulfuric acid and particles, along with a few other findings existence of life on Venus There is no convincing evidence for that

As a result, Venus’s intense atmospheric and extreme temperatures make it uninhabitable. of the world “cosmic twin” Although Venus is far from habitable.
