This applet has been designed to help students visualize the structure and composition of the planets. Students can click on the various planets (3) to display an information box which shows a cut-away image of the planet. Students can then drag the information window (2) to place it adjacent to any of the other planets' windows for comparision and contrast.
Despite not being to scale, the images and diagrams still allow students to compare planetary structure and composition.
Use the "Reset" button (4) to return the information windows to their original place.
