Rate the following essay on its writing, argument, and language skills:
Venus is the second planet from the sun. They are often referred to as Earth's "twin" since they have so much in common.

The planet Venus is worthy studying because it's still considered and plays an important role in our planet and in our solar system. It is also worth studying because people, even from today, are still very curious about Venus. Besides the ninety-seven percent atmosphere of carbon dioxide and the temperature being eight-hundred degrees Fahrenheit, Venus and Earth share characteristics as "sisters." Astronomers thought that a long time ago, Venus was possibly covered with oceans and supported life just like Earth. Still today, Venus provides all sorts of features that Earth has, like mountains and valleys. It is said in the passage, "Venus can sometimes be our nearest option for planetary visit." NASA has made all sorts of plans, ideas and studies for visiting the complicated planet. They have built all sorts of machines for it to survive. There was this machine they built and did some testing and experiments about them. It was highly manageable and "survivable for humans."

In conclusion, Venus is worth studying because it plays an important role for our solar system despite the lack of density of Venus's atmosphere, scientists today still continue studying and researching about Venus. Nobody has ever survived coming back from Venus but that doesn't stop the researchers at all.
