Characteristics of Venus

1, Venus is an Earth-like planet, and is sometimes called the "sister star" of the Earth because its mass is similar to that of the Earth.

It is also the only planet in the solar system without magnetic field.

3. Among the eight planets, Venus's orbit is the closest to a circle with the smallest eccentricity.

There are dense atmosphere and clouds around Venus. The surface temperature is as high as 500℃, and the atmospheric pressure is about the atmospheric pressure of the earth.

Venus rotates in the opposite direction to other planets, from east to west. Therefore, on Venus, the sun rises in the west and sets in the east.

Astral structure of Venus:

Theoretically, the internal structure of Venus is similar to that of the Earth, with an iron-nickel core and a radius of about 3 100km. The middle layer is a "mantle" mainly composed of silicon, oxygen, iron, magnesium and other compounds, and the outer layer is a very thin "shell" mainly composed of silicon compounds.

According to the structure of the earth, it is speculated that the main components of Venus mantle are silicates dominated by olivine and pyroxene, and a crust dominated by silicates with an iron-nickel alloy core at the center.

Venus has an average density of 5.24g/cm3, ranking third among the eight planets (Pluto was classified as a dwarf planet in 2006, so it is called the eight planets).

An iron core with a diameter of 3,000 kilometers, molten stones filled most of the planets to form the mantle.
