VENUS BECAUSE BECAUSE IT IS THE hottest planet in the SOLAR SYSTEM. The surface of Venus is constantly shaken by fierce volcanic eruptions. Currently, space scientists know of nearly 1,600 volcanoes on the surface of Venus, but in reality, there may be many more simply because we humans are too small to observe with our own eyes. Use existing technical technologies and equipment. Furthermore, the thick mantle covered by thick clouds (forming sulfuric acid) spread across the entire planet, making it difficult for scientists to observe.
