text: Venus, also known as the "Evening Star", since it is so easy to see at night, and our "Sister Planet", is a very difficult place to study. The size of Venus is why it is known as our Sister Planet, it has almost the same density, mass, and size of Earth. But on the contrast, its atmosphere is very different from ours. The atmosphere on the planet has many storms that are highly electrical ,hence, lightning can strike a craft out of the sky. And the atmosphere is made up of 97% carbon dioxide. The blankets of carbon dioxide make it hard to see into the planet. The clouds of carbon dioxide on the planet are highly corrosive because of sulfuric acid. Any craft made of any type of metal will melt in about roughly 2-3 days depending on the size of the craft. The Atmospheric pressure on the planet is about 90 times greater than we experience on Earth. The temperature on the ground averages over 800 degrees Farenheit.
