star.
• The sun is made of
about 70% hydrogen
and 28% helium.
Orbit
• A path that an object takes as it
moves around the sun.
Planet
• A large body of rock or gas that
orbits around the sun.

Jupiter
Saturn
Uranus
Neptune
How are the inner planets the
same?
• Smaller and warmer
• Have rocky surfaces
• Have no more than 2 moons
How are the outer planets ?
• Made mostly of frozen gas
• Larger and colder
• Have more than 2 moons
Mercury
• Mercury is solid and is
covered with craters.
• Mercury has almost no
atmosphere.
• Mercury is the eighth
largest planet.
Venus
• Venus is the sixth
largest planet. It’s about
three-fourths the size of
earth.
• The surface is rocky and
very hot. The
atmosphere completely
hides the surface and
traps the heat.
Earth
• Earth is the fifth largest planet and the third from the
sun.
• Liquid covers 71 percent of the Earth’s surface.
• The Earth has one moon.
Moon
Mars
• Mars is the fourth
planet from the sun.
• Mars has a thin
atmosphere that
contains mostly carbon
dioxide.
• Mars has two small
moons.
Moons of Mars
Phobos
Deimos
Jupiter
Jupiter’s Red Spot
• The Great Red Spot, a
huge storm of swirling
gas that has lasted for
hundreds of years.
• Jupiter does not have a
solid surface. The planet
is a ball of liquid
surrounded by gas.
Saturn
• Saturn is the second largest planet and the sixth from
the sun.
• Saturn is made of materials that are lighter than
water. If you could fit Saturn in a lake, it would float!
Rings of Saturn
• Saturn’s rings are not
solid; they are
composed of small
countless particles.
• The rings are very thin.
Though they’re
250,000km or more in
diameter, they’re less
than one kilometer
thick.
Uranus
• Uranus is the third
largest planet and the
seventh from the sun.
• Uranus is one of the
giant gas planets.
• Uranus is blue-green
because of the methane
in its atmosphere.
Neptune
• Neptune is the fourth
largest planet and the
eight from the sun.
• Because of the orbits,
from 1979 to 1999,
Neptune was the ninth
planet.
• Like Uranus, the
methane gives Neptune
its color.
What planet is the largest?
When is a comet visible from
Earth?
• A comet is visible when it passes
close to the sun.
