THE TITLE ON THIS CARD IS:
THE OUTER  PLANETS
The four outer planets, or giant planets (sometimes called Jovian planets), collectively make up 99% of
the mass known to orbit the Sun.[g] Jupiter and Saturn are together over 400 times the mass of Earth
and consist overwhelmingly of hydrogen and helium; Uranus and Neptune are far less massive
(<20 Earth masses each) and are composed primarily of ices. For these reasons, some astronomers
suggest they belong in their own category, "ice giants".[87] All four giant planets have rings, although only
Saturn's ring system is easily observed from Earth. The term superior planet designates planets outside
Earth's orbit and thus includes both the outer planets and Mars.
