78. SATURN, the remotest of all the Planets, is about 777 millions of
miles from the Sun; and, travelling at the rate of 18 thousand miles
every hour, as in the circle marked ♄, performs his annual circuit in 29
years 167 days and 5 hours of our time; which makes only one year to
that Planet. His diameter is 67,000 miles; and therefore he is near 600
times as big as the Earth.
