ASTR330: Spring 2003
The Solar System

Course Description:

This course is intended for juniors and seniors who are not majoring in the physical sciences and who have successfully completed either ASTR 100 or ASTR 101 and also the CORE Distributive Studies Requirement in Mathematics and Sciences. The course will emphasize the way in which we combine different types of information to answer fundamental questions about the Solar System, such as

This means that we will consider the important physical and chemical processes in the Solar System, illustrating them with examples from the real bodies in the Solar System, rather than trying to inventory each of the objects in the Solar System separately.

We will consider how our ideas have changed over the centuries, as well as the most modern data. What was Galileo's view of the Solar System? How has our view changed and how has the spacecraft named for Galileo helped to change this view? What are all the new Kuiper Belt (or Trans-Neptunian) Objects that we have discovered in the outer Solar System over the last several years and what relation do they have to the objects we have known about for centuries? Why do we need to send spacecraft out into the Solar System to learn about the Solar System?

We will use very little mathematics in this course but we will use a lot of physical reasoning and we will use information from geology, meteorology, and physics as well as from astronomy, all sciences that have contributed importantly to planetary science. Thus you will be expected to master an extensive body of knowledge.

Course Expectations:

Attendance: In order to succeed in this course, I expect you to attend all lectures. This is very important! The material on the homeworks and exams are based upon the material covered in the lectures and in the text. If you have to miss a lecture be sure to look at another student's notes and make sure that you understand what was covered. There will be times during the semester when I will ask for written responses to questions. Your written answers will count towards your grade in the class.

Preparation: I expect you to be prepared to work. You will understand the lecture more easily if you preview the reading assignment. A more careful reading is recommended after lecture. It is also good to study your class notes sometime before the next lecture to make sure that everything is clear. I encourage you to ask questions in class, during office hours, or over email.

Study Habits: Study wisely and ask for help if you need it. If you just cram the night before the exam, you probably will not do very well. It is better (and easier) if you keep up with the material on a daily basis. Make it a point to read the chapters in pace with the lectures; this is one of the best study habits you can have. If you have questions, please see me.


I grade on a point scale with different assignments weighted as shown in the table. A description of each of these components is contained in this syllabus.

Exam I
Exam II
Exam III

Letter grades will be assigned based upon your curved cumulative score. Grades for some discussion sections may be adjusted slightly so that the average grade given by each TA is similar. Here is how your grade will be determined from your point total in the class.

Letter Grade
Course Total

The point scale makes it possible for everyone in the class to do well. For example, if everyone scores above 80% in the course, you would all receive either a B- or better letter grade. I do use +/- modifiers - you will get a "+" if you are in roughly the upper 1/3 of students with the same letter grade and a "-" if you are in the lower 1/3. I may adjust the number of points required to get a given grade depending on the class averages; however, any adjustment will make it easier to get a given grade, never more difficult. You can monitor my current estimate of your grade from the class webpage as the semester progresses.


There will be three in-class exams. These exams are closed book with no notes and no calculators allowed. Each exam will consist of short answer questions and three or four essay questions. These exams are incremental (i.e., non-cumulative) checkups on how well you have learned the material. The schedule of lectures included in this syllabus shows what material will be covered on each exam. If for whatever reason, the University is officially closed on the exam date, the exam date shifts to the next lecture date.

According to University rules, the final exam for this course will be held on Wednesday, May 21 from 1:30pm to 3:30pm in CSS 2400. This final exam is cumulative, that is, it will cover all material discussed in this course. However, since chapters 12,16, and 18 will not be covered by the midterm exams (see Lecture Schedule), the weight on these chapters will be higher than on earlier chapters. The final will include short answer, essay, and problem solving questions with the exact combination to be determined. This exam is also closed book with no notes and no calculators allowed.

Missed Exams

If you are not able to take an exam due to illness or other legitimate reasons (as outlined in the Academic Info section of the schedule of classes) and you wish to take a make-up exam, you must


There are a total of four homeworks in this course. Homework #1 is included with this syllabus and can also be obtained from the Assignments link from the class website. Future homeworks will be also be available from the website. Please type or writeup your assignments neatly.

Although you may discuss the homework problems with your friends, the final writeup must be in your own words. Copying from a friend's homework, copying from a book, or allowing a friend to copy your homework is academic dishonesty and will not be tolerated in this class. If you consult a reference other than the course text, please acknowledge it in your homework - this includes websites!

Extra Credit

There will be no extra credit papers. The following are the only ways to earn extra credit in this class:

Class Web Page

The World Wide Web is a very useful resource that we will make extensive use of in this class. All students should obtain a computer account, which will include email and internet access. The webpage for this course

will contain links to course information, supplementary readings, and interactive programs to make ASTR330 fun and to help you learn. You will be able to monitor your estimated grade in the class as the semester progresses. In addition, this site is also a gateway to many other astronomy links, including sites with up-to-date astronomical images that are made available to the public from telescopes in space and on the ground.
