The golden planet
Appearance and Size
The golden or yellow planet Venus is certainly not the largest, but the most dense and heaviest in our system. It's 12,120km/7,520miles in diameter and it weighs 487,000,000,000,000,000,000,000kg! Venus is the second largest terrestrial planet in our system. (terrestrial planet means a planet made out of rocks. Earth is the biggest in our system and Venus is 95% of the size of Earth). Venus has no ring. On its land, there are lots of mountains and volcanoes. Coronae, big, round crownlike shapes are on Venus too. There are also tesserae on Venus too. They are raised places that look like hills and valleys formed in different directions. Venus do have craters but less than Mercury and Mars, and that occurs because Venus has a thick atmosphere.
Just like our home Earth, Venus has an atmosphere layer too, but it is very different from ours. The atmosphere pressure on Venus is very high, it is 90 times stronger than the atmosphere on Earth. One of the reasons why the pressure is so high is because the atmosphere is very thick. The thick clouds on Venus are all made out of surfuric acid and carbon dioxide, which are chemicals that are extremely dangerous to human. Since the atmosphere is very thick, when the sun ray shines through the atmosphere and onto Venus, a lot of is cannot come back out. That is called a greenhouse effect. The greenhouse effect on Venus is so strong and that what makes Venus's temperature so high.
Thanks a lot for reading and hopefully that answer the questions.
