What are Some Properties of Venus' Atmosphere?

Venus is one of the eight planets in the solar system. It is the second planet in the order of near to far from the sun, 0.725 astronomical units from the sun. It is the planet closest to Earth (Mars is sometimes closer). The ancient Romans called it Venus, in ancient China it was called Chang Geng, Qiming, Taibai or Taibai Venus, and in ancient Greek mythology it was called Aphrodite. The revolution period is 224.71 Earth days.

There is no direct data on the internal structure of Venus. From theoretical calculations, Venus' internal structure is similar to that of the earth. It has an iron-nickel core with a radius of about 3,100 kilometers. The middle layer is mainly composed of silicon, oxygen, iron, The "mantle" composed of compounds such as magnesium, while the outer layer is a thin "shell" composed mainly of silicon compounds.

Scientists speculate that the internal structure of Venus may be similar to that of the Earth. Based on the structure of the Earth, Venus's ground function is composed mainly of olivine and pyroxene-based silicates, and a layer of silicate-based crust.

On the surface of Venus, there are 70% plains, 20% highlands, and 10% lowlands.

On the Great Plains on the surface of Venus are two major continental-like highlands. Highlands in the north

Venus rotates in the opposite direction from most planets in the solar system.

Venus orbits the sun in 224.65 days, with an average distance of 180 million kilometers. Although all planetary orbits are elliptical, the eccentricity of Venus's orbit is less than 0.01. When Venus is located between the earth and the sun, it is called down-coupling (inward-coupling), which will be closer to the earth than any planet. The average distance is 41 million kilometers, and the closing occurs every 584 days on average. As the eccentricities of Earth's orbit and Venus' orbit are decreasing, the closest distance between the two planets will gradually increase. During periods of high eccentricity, the distance between Venus and Earth can approach 38.2 million kilometers.

Venus has a rotation period of 243 days, the slowest rotation among major planets. Venus's

Venus can be described as densely volcanic and has the most volcanoes in the solar system.

Venus' sky is orange. There is also a thunderbolt on Venus, and the largest lightning strike ever recorded lasted 15 minutes.

Venus' atmosphere is mainly composed of carbon dioxide and contains a small amount of

It used to be thought that Venus had a satellite called
