Answer 1

Mercury. . 20 cm
Venus. . . . 35 cm
Earth. . . . 50 cm
Mars. . . . . 80 cm
Asteroids 1.40 m
Jupiter. . 2.60 m
Saturn. . . 5.00 m
Uranus. . . 9.80 m
Neptune. 19.40 m
Pluto. . . . 38.60 m

Answer 2

kumorifox has the right idea but he misplaced a decimal point. Look up the diameters of the sun and the earth, and you'll find that the sun is about 870,000 miles across, and the earth about 8,000 miles across. That means the sun is (870,000/8,000) = 109 times as big as the earth. (You'll get the same answer if you find the sizes in km rather than miles.) That means your model sun has to be 109 times as big as your model earth. model sun = 109 × 30 cm = 3270 cm = 32.7 meters. (Ten times bigger than what kumorifox said.) That's more than 100 feet in diameter. Good luck with your model!
