Answer to Question 1

E

Answer to Question 2

Uranus was discovered with the aid of a telescope by William Herschel. Neptune was discovered when astronomers realized that Uranus was being influenced by another body as it moved around its orbit. They were thereby able to predict the precise location in the sky in which to look for Neptune, which was subsequently found by telescope.

Lost in Space Some things are worse than an exam. Just as you thought the exam was about over, you were plucked from Earth by a strange alien being. After performing gruesome experiments on your body and your mind, the alien gave you a life-support belt and dumped you somewhere in the solar system. This happened several times. A brief description of each place at which you were left by the alien follows. Identify your location each time. Be as specific as possible, and be sure to include a brief explanation for your answer.
