The objective of this project is to observe as many planets of the solar system as possible. You will more than likely not be able to observe them all. In fact, a collection of two or three is necessary, though it is recommended that you try for others. For some references on the observation of each of the planets individually, look to the other project entries. While more planets are required to be spotted, your actual work with each of the planets will be less intensive than if it was your primary project.
Here is a brief synopsis of the visibility of the various planets of our solar system:
Reference some of the other planetary projects to see what sort of data can be collected and interpreted. Keep in mind that this is a general survey, and one should not have to analyze and pictures too closely.
