ASTR 101
HOMEWORK ASSIGNMENTS

Homework problems are assigned from the 8th edition of the textbook The Cosmic Perspective - The Solar System.
Be sure you are doing the right homework problems! Other editions of the text will have different questions.

There are 6 homeworks with 6 problems worth 5 points each, plus one extra credit problem worth 2 points for each homework assignment. There are no make-ups, for illness or otherwise, but we will drop the lowest homework.

All homeworks are due in class at the beginning of lecture on the date specified. Homeworks are late (and suffer a 5 point penalty) after lecture begins. The end of lecture is the last opportunity to turn in homeworks with a 5 point late penalty. After that, homeworks will no longer be accepted.

Remember to put your name on your homework! Be sure to type or write neatly - we can not give credit for things we can not read.
