Venus 1 What's the mystery? Besides Mercury, the closest planet to the sun, Venus is the only planet without satellites. You know, among the eight planets, Jupiter has 79 satellites, and even the earth like Venus has a moon, but Venus has always been in a state of zero satellites.
There are already 20,000 pyramids on Venus, and probes from the United States and the former Soviet Union have taken photos. Most of these pyramid cities are circular and expand around the central building.
A physicist in the former Soviet Union once found a sphinx on the surface of Venus. Just like the mysterious Sphinx on Mars, it looks like a delicate face stone with a raised teardrop-like object in front, which was once considered as a warning sign of Venus.
Hawking once said that Venus will be the future of the earth if greenhouse gas emissions are not controlled. According to scientists' speculation, Venus was the same as the earth 800 years ago, but then the concentration of greenhouse gases became higher and higher, and the strong greenhouse effect led to the mass extinction of organisms, and the surface environment became worse and worse.
Venus rotates in the opposite direction to most planets in the solar system, mainly from east to west, so the sun seen on Venus may rise in the west and set in the east.
6. Although Venus is like a twin with the Earth, it is not as attractive as Mars, mainly because its atmosphere is almost a sulfuric acid cloud, and 90% of the air on its surface is carbon dioxide, so it is the most dangerous planet in the solar system.
