seasons?
 Yes, Saturn has seasons,
like the planet Earth,
buts Saturn’s season’s
last over 7 years. There
is also hurricanes and
very cold air on Saturn.

16. URANUS
 Composed mainly of hydrogen and helium gases, its
mass (weight) is over 14 times that of the Earth, its
diameter is 4 times that of Earth

and 14 minutes
 Can sometimes be seen with the naked eye
 Has a 15 moons

17. URANUS
Q&A
 What are the most interesting features of Uranus?
 The planets is a blue-green color because of methane gas in the
atmosphere. It may have lower %’s of light elements and a
greater % of water. Also Uranus’s atmosphere is mainly
hydrogen and methane.

21. PLUTO
Q&A
 Why is Pluto now considered a dwarf planet?
 It was declassified because of its strange elliptical orbit
as opposed to all the other planets’ orbits which are
circular, Pluto’s orbit is the only planet which is
elliptical (like and oval) around the sun
