Venus is one of the eight planets in the Solar System, the second in order of proximity and distance from the Sun. It is the closest planet to Earth. (Mars is sometimes closer) Ancient China called it Chang Gung, Qiming, Taibai or Taibai Venus. The orbital period is 224.71 Earth days. The night sky is second brightest after the Moon, and Venus doesn't get to its maximum brightness until just before sunrise or later at sunset. Therefore it sometimes appears in the eastern sky early in the morning, called "Enlightenment"; in the evening it is on the west side of the sky. Venus is an Earth-like planet that is sometimes referred to as Earth's "sister star" because of its similar mass to Earth, and is the only planet in the solar system that does not have a magnetic field.
Venus
Regarding the internal structure of Venus, there is no direct data, from theoretical calculations, the internal structure of Venus is similar to that of the Earth, with a radius of about 3,100 kilometers of iron-nickel nuclei, the middle layer is mainly composed of silicon, oxygen, iron, magnesium and other compounds "mantle", while the outer layer is mainly composed of silicon compounds very thin "shell".
Scientists speculate that the internal structure of Venus may be similar to that of The Earth, and according to the structure of the Earth, the main components of Venus's earth letter are olivine and pyroxene silicate, as well as a layer of silicate-dominated crust, and the center is the core composed of ferronic nickel alloys. Venus has an average density of 5.24 g/cc, second only to Earth and Mercury, and is the third of the eight planets (Pluto was classified as a dwarf planet in 2006, so it is called the Eight Planets).
A 3,000 km diameter iron core with molten stones filling most of the planet with mantles. Much thicker. Just like Earth, convection in the mantle creates pressure on the surface, but it is relieved by a relatively small number of areas so that it does not break at the plate boundaries as on Earth, where the crust is destroyed.
