Why are scientists interested in it? Titan is Saturn’s giant moon, it has a surface tempurature of around 270 degrees fahrenheit , it has a think atmosphere that’s regarded by scientists as one of the most complex chemical environment in our solar system Critical Thinking Questions 1. How do the outer planets differ from the inner planets?

Inner planets are classified as rocky planets while the outer planets are classified as gas giants, the outer planets have a greater mass then all the inner planets. The outer planets also have small cores. They are also cooler than the inner planets. 2. Which of the outer planets is MOST like Earth? How? Saturn because they both have at least one moon, they both get seasons like summer and winter, and the gravity is similar. 3. Do you think the outer planets contain any life?

They defined planets as bodies that orbited the sun, now they know that planets don’t just orbit the sun they can be pulled in and orbit other planets due to the gravity, and now we have a better conception on planets and their gravitational forces.
