Your mission is to draw the planets (and Pluto!). Because the diameters are so large, you will need to use math and proportions to get them all to fit on the screen. Their diameters are: Mercury - 4,879 km Venus - 12,104 km Earth - 12,756 km Mars - 6,779 km Jupiter - 142,984 km Saturn - 120,536 km Uranus - 50,724 km Neptune - 49,244 km Pluto - 1,475 km
