What's the name of Venus? Why is it so bright?

Venus is one of the eight planets and the brightest star in the sky. Venus belongs to the earth-like planet, and it has more than one name. So what's the name of Venus? Why is it so bright? Then let the constellation knowledge reveal the secret for everyone!

What's the name of Venus? The ancient Romans called it Venus, China called it Chang Geng, Qi Ming, Taibai or Taibai Venus, and Aphrodite in ancient Greek mythology.

Why is Venus so bright? Venus is a mysterious planet. It is called the "sister planet" of the earth and is very similar to the earth in size and mass. Venus and Mars are basically the closest planets to the earth, but because they are bigger than Mars and closer to the sun, they are the brightest celestial bodies in our sky. Part of the reason why Venus is so bright in the night sky is its atmosphere. Its "atmosphere" has a high density, with more than 95% of its components being gaseous carbon dioxide and the rest being nitrogen. This means that Venus can store most of the heat energy. It is about 40 million kilometers closer to the sun than the Earth, so it can get more heat. The surface temperature can easily reach 700℃. Although Mercury is closer to the sun, the average temperature of Venus is actually higher than that of Mercury. If you want to know the "worst case" of the greenhouse effect, you only need to look at Venus.

This atmosphere has caused some extreme weather, which is the most famous feature of Venus as a planet. A probe sent to the surface of Venus for a "suicide mission" observed lightning, which usually occurred in several clouds between its surface and space. Both sulfuric acid condensation and rainfall occur in the upper atmosphere, but they often evaporate before falling to the planet's surface. Most of the surface of Venus is formed by volcanic activity, which makes it more like the Earth billions of years ago. The so-called "volcanic plains" dominate the planet's surface. This is a barren landscape. Compared with it, even Mars has become better: at least this red planet can let you see the background of many stars. On Venus, the atmosphere will prevent us from taking such photos. So the shots we have at present, such as the one below, are also very vague and meaningless. Venus is really hidden too deep.

Scientists have little information about the interior of Venus, such as the source of lava from volcanic eruptions. In fact, we hardly have any information about the mass distribution of Venus. The planetary dynamics of Venus has been the interest of astronomers for many years, and its rotation direction is one of two special cases. Uranus is almost in orbit, while Venus rotates in the opposite direction to other planets. Astronomers believe that a long time ago, Venus expanded violently with another celestial body, which led to its reverse rotation. In fact, we can think of Venus as the earth millions of years after the end of the world. Venus's environment is considered to be the planet most similar to that of the early earth, but the evaporation of the ocean led to the runaway greenhouse effect, which led to the planet we see today. This may be caused by the same destroyer Conan event that caused Venus to rotate 180, but in any case, the planet was changed forever.
