    In Astronomy 101: The Solar System students explore topics such as celestial motions of earth, the sun, the moon, and the planets, the nature of light, dwarf planets, asteroids, and comets. WebAssign provides online homework questions from this title with solutions and links to interactive lecture notes for each lesson, as well as suggested readings, lecture videos, and relevant links to wikipedia and other outside sources.

    The questions in this sample assignment come from chapter 4 of the book, but are representative of the style of the rest of the questions.

    Each question has a solution and a link to the lecture notes.
