Star Classification Test

Please be patient while applet loads. Thank you.

Put your mouse pointer on a Star on the left and hold down the mouse button. While holding down the button, move the mouse pointer to the place that you think the Star on the left should be classified on the H-R Diagram. When you release the mouse button, the picture of the star will move to that spot.
