find outer edge astreoid belt calculation using this To see what the scaled distance between the Sun and a planet is, you would calculate (Your Scale Factor) (Semi-major axis)=Planet Scaled Distance Calculated Do this for each line in the table, multiplying the Semi-major axis value by Your Scale Factor. Object Semi-major axis (km) Scaled Distance Calculated (cm) Sun ----------- ----------- Mercury 5.83 x 10^7 1.510 Venus 1.08 x 10^8 2.761 Earth 1.50 x 10^8 4.180 Mars 2.27 x 10^8 5.990 Asteroid Belt (inner edge) 3.28 X 10^8 8.335 to 13.107 Asteroid Belt (outer edge) 4.77 X 10^8 Jupiter 7.78 x 10^8 19.746 Saturn 1.43 x 10^9 36.294 Uranus 2.87 x 10^9 72.852 Neptune 4.50 x 10^9 115.230 Pluto 5.91 x 10^9 150.000
