Venus- The hot and volcanic planet|Technospace

 Venus is the hottest and the second planet in the Solar System, is also known as the "sister of Earth". It is named after the Roman God of Love and Beauty.

Even though Venus isn't the closest planet to the Sun, it is still the hottest. It has a thick atmosphere full of the greenhouse gas carbon dioxide and clouds made of sulfuric acid. The atmosphere traps heat and keeps Venus toasty warm. It's so hot on Venus, metals like lead would be puddles of melted liquid. Venus looks like a very active planet. It has mountains and volcanoes. Venus is similar in size to Earth. Earth is just a little bit bigger. Venus is unusual because it spins the opposite direction of Earth and most other planets. And its rotation is very slow. In ancient times, Venus was often thought to be two different stars, the evening star and the morning star — that is, the ones that first appeared at sunset and sunrise. In Latin, they were respectively known as Vesper and Lucifer. In Christian times, Lucifer, or "light-bringer," became known as the name of Satan before his fall. However, further observations of Venus in the space age show a very hellish environment. This makes Venus a very difficult planet to observe from up close, because spacecraft do not survive long on its surface. Venus has a thick, toxic atmosphere filled with carbon dioxide and it’s perpetually shrouded in thick, yellowish clouds of mostly sulfuric acid that trap heat, causing a runaway greenhouse effect. It’s the hottest planet in our solar system, even though Mercury is closer to the Sun. Venus has crushing air pressure at its surface – more than 90 times that of Earth – similar to the pressure you'd encounter a mile below the ocean on Earth.

The surface temperature of Venus is more than 490°C. Venus has been visited by over 20 spacecrafts. The first one to go is Mariner 2 in 1962. The last satellite is Magellan in 1990. Venus has no moons. 

 Sif Mons, a volcano on planet venus is about 2 kms high and about 300 kms in diameter.
