The chart of the solar system above, while showing relative distances in a degree,
is not in true proportion to distances in the solar system. Chart above, for example,
shows Neptune approximately nine times as far from the sun as is the earth, whereas
it is actually about thirty times as far. Orbits of the planets on the chart are rep-
resented as circular, but they are elliptical to small, but varying degree with refer-
ence to the major planets, and decidedly so with reference to the asteroids, or minor
planets. Some of the asteroids are twice as far front the sun at aphelion as at peri-
helion. At least one of them is known to come within the orbit of Mars, and within
13,000,000 miles of the orbit of the earth at perihelion.
THE SOLAR SYSTEM.
The solar system is composed of the
sun, eight major and some 800 or more
minor planets which revolve in- elliptical
orbits around the sun, together with sat-
ellites which revolve around certain-of 'the
major planets. Beyond the solar system
lies the universe of fixed stars-presum-
ably the great suns -of other solar sys-
tems-at distances so remote that -even
the nearest is beyond the grasp of the
imagination. If the distance from the
earth to the sun, approximately 9200I;iO
miles, is taken as a unit of measurement,
then the nearest fixed star, Alpha ,Cen-
tauri, is 225,000 units distant. It takes
