According to Alemi and Stevenson, about 10 million years later, another impact reversed the planet's turn, causing Venus' moons to gradually spiral inward until they collided and merged with Venus.

If subsequent collisions create moons, they will be absorbed in the same way.

Whether Alemi and Stevenson's research will be accepted by the scientific community remains unclear.

Volcano distribution:

Venus is the most volcanic planet in the solar system.

More than 1,600 large volcanoes and volcanic features have been discovered.

In addition, there are countless smaller volcanoes, but no one has counted their number, and it is estimated that the total number is more than 100,000, or even a million.

Venus volcanoes have different shapes.

In addition to the more common shield volcanoes, there are many complex volcanic features and special volcanic structures.

So far, scientists have not found active volcanoes here, but due to limited research data, although most of the Venus volcanoes have already been extinguished, the possibility that a small number are still active cannot be ruled out.

Venus and Earth have a lot in common.

They are similar in size and volume.

Venus is also the closest planet to Earth in the solar system and is also surrounded by clouds and a thick atmosphere.

Like Earth, the surface age of Venus is also very young, about 500 million years old.

However, there are also many differences in these basic similarities.

The atmosphere of Venus is mostly carbon dioxide, so its surface has a strong greenhouse effect, and its atmospheric pressure is about 90 times that of the earth, which is almost equivalent to the water pressure at the next kilometer of the earth's sea surface.

There is no water on the surface of Venus, and there is no moisture in the air. The main component of its clouds is sulfuric acid, and the height of the clouds is much higher than that of the earth.

Due to the high atmospheric pressure, the wind speed on Venus is correspondingly slow.

This means that the surface of Venus is neither affected by wind nor washed by rain.

Therefore, the volcanic features of Venus can remain clearly for a long time.

Venus has no plate tectonics, no linear volcanic chains, and no obvious plate demise zone.

Although there are canyons on Venus, there is no trench that looks like Earth.

There are indications that the eruption of Venus volcanoes is also relatively simple.

The solidified lava layers show that when most Venus volcanoes erupted, the lava flows that flowed out did not show any signs of violent eruptions and ejection of volcanic ash, and even the lava was not as muddy and sticky as the earth's lava.

This phenomenon is not difficult to understand.

Due to explosive volcanic eruptions with high atmospheric pressure, a huge amount of gas is required in the lava.

On Earth, the main gas responsible for the violent eruption of lava is water vapor, and Venus lacks water molecules.

In addition, the vast majority of viscous lava flows and volcanic ash eruptions on Earth occur in tectonic plates.

Therefore, the lack of a plate extinction zone also greatly reduces the chances of a violent eruption of Venus' volcanoes.

Large shield volcano:

Venus has more than 150 large shield volcanoes.

These shields are mostly between 100 kilometers and 600 kilometers in diameter, and about 0.3 to 5 kilometers in height. The largest of them is 700 kilometers in diameter and 5.5 kilometers high.

Compared to shield volcanoes on Earth, Venus volcanoes appear flatter.

In fact, the largest Venus shield volcano has a base diameter close to that of the Olympus volcano on Mars, but is much smaller than Olympus due to insufficient height.

Shield volcanoes on Mars are similar to shield volcanoes on Earth.

Most of them are covered by long radial lava flows with gentle slopes. Most volcanoes have jet holes in the center.

Therefore, scientists speculate that these shields are made of basalt, similar to the volcanoes in Hawaii.

The shield volcanoes on Venus are scattered and not like the volcanic chains on Earth.

This shows that Venus has no active plate tectonics.
