The average density of Venus is 5.24g/cm3, second only to Earth and Mercury, and 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-kilometer-diameter iron core, the molten stone that fills most of the planet's mantle, is much thicker.

Like Earth, convection in the mantle puts pressure on the surface, but it is relieved by a relatively small number of regions so that it doesn't break down at the plate boundaries like on Earth.

Venus was originally habitable, but the ocean on it "killed" it.

The surface of Venus is 70% plain, 20% high, and 10% low.

There are two major continental highlands on the Great Plains on the surface of Venus.

The northern highland, called Ishtar Terra, has the highest Maxwell Mountains on Venus (about two kilometers higher than the Himalayas), named after James Clark Maxwell.

The Lakshmi Plateau is surrounded by the Maxwell Montes.

Ishtar Land is about the size of Australia.

In the southern hemisphere is the larger Aphrodite Terra, which is about the size of South America.

Between these highlands are many expansive lowlands, including the Etalanta Plains, Guinevere, and Lavinia.

With the exception of the Maxwell Mountains, all Venus features are named after real or mythological women.

Because Venus' thick atmosphere slows down meteors and other celestial bodies before they reach the surface of Venus, the craters on Venus are no larger than 3.2 kilometers.

About 90% of the surface of Venus is formed by basalt lava that solidified not long ago. Of course, there are also a very small number of craters. The interior of Venus may be similar to that of Earth: a core with a radius of about 3000 kilometers and a mantle made of lava. most of Venus.

Recent data from the Magellan spacecraft suggest that Venus' crust is thicker and stronger than previously thought.

It can be inferred from this that Venus does not have movable plate tectonics like Earth, but there are a large number of regular volcanic eruptions all over the surface of Venus.

The oldest features on Venus are only 800 million years old, and most areas are young (but also hundreds of millions of years old).

Widespread wildfires scrubbed the early surface at that time, including several large craters that formed early on Venus. Venus' volcanoes are still active in isolated geological hotspots.

Venus's own magnetic field is very weak compared to other planets in the solar system.

This may be due to the fact that Venus's rotation is not fast enough, and the liquid iron in its core has a weak magnetic field caused by cutting the magnetic field lines.

In this way, the solar wind can hit the upper atmosphere of Venus without buffering.

At the earliest times, Venus and Earth were thought to have the same amount of water, however, solar wind attacks have caused water vapor in Venus' upper atmosphere to break down into hydrogen and oxygen.

The hydrogen atom escaped into space because of its small mass.

The proportion of deuterium (an isotope of hydrogen that is more massive and escapes more slowly) on Venus seems to support this theory.

And oxygen is combined with substances in the earth's crust, so there is no oxygen in the atmosphere.

The surface of Venus is very dry, so the rocks on Venus are harder than those on Earth, resulting in steeper mountains, cliffs and other landforms.

A 1,200-kilometer long canyon that crosses the equator from south to north is the largest canyon among the eight planets.

Venus Structure:

According to probe detection, it was found that Venus magma contains water.
