Note: The term planet was first used to distinguish those
stars which have an apparent motion through the
constellations from the fixed stars, which retain their
relative places unchanged. The inferior planets are
Mercury and Venus, which are nearer to the sun than is
the earth; the superior planets are Mars, the
asteroids, Jupiter, Saturn, Uranus, and Neptune, which
are farther from the sun than is the earth. Primary
planets are those which revolve about the sun;
secondary planets, or moons, are those which revolve
around the primary planets as satellites, and at the
same time revolve with them about the sun.
