To assist the mind in framing a conception of the magnitude and relative

distances of the primary planets, let us have recourse to the following

method. The dome of St. Paul’s is 145 feet in diameter. Suppose a globe

of this size to represent the Sun; then a globe of 9⁷⁄₁₀ inches will

represent Mercury; one of 17⁹⁄₁₀ inches, Venus; one of 18 inches, the

Earth; one of 5 inches diameter, the Moon, (whose distance from the

earth is 240,000 miles;) one of 10 inches, Mars; one of 15 feet,

Jupiter; and one of 11½ feet, Saturn, with his ring four feet broad, and

at the same distance from his body all round.
