Our Solar
System
Definition Of A Planet
*An object in orbit around a star but does not give off its own light,
rather it shines by reflecting sunlight.
*Planets close to the sun are rocky (inner planets)
*Planets farther away from the sun consist mostly of gases and liquids
(outer planets)
*There are eight major planets in our solar system.
Inner Planets are called inner
planets because they orbit
close to the sun. These planets
are:
Mercury
Venus
Earth
Mars
Outer Planets are called outer
planets because they orbit far
from the sun. These planets are
called: Jupiter Saturn Uranus Neptune
Asteroids are sometimes called minor planets because the are made up
of rocks and metal. The rocks come in many sizes.
They are found in a large area between the orbits of Mars
and Jupiter.
This area is known as the Asteroid Belt
MERCURY
Closest planet to the sun.
Second hottest planet.
Now the smallest planet since Pluto is no
longer one.
Has no moons.
Can only be seen from Earth at sunrise or
sunset because it is so close to the sun
Rocky, cratered surface.
VENUS
 Second planet from the sun.
 The hottest planet in the Solar System.
 Covered with fast-moving sulphuric acid
clouds which trap the heat from the sun.
 It’s atmosphere is mostly carbon dioxide.
 Venus is slightly smaller than Earth.
 It has no moons.
 Know as the “morning star” since it is
visible and quite bright at dawn or dusk.
This is because it is closer to the sun than
we are.
 Rotates clockwise.
EARTH
Third planet from the sun.
Densest planet in the Solar system.
Has one moon.
Fifth largest planet in the Solar System.
Has an atmosphere of nitrogen, oxygen,
argon, carbon dioxide, and trace amounts of
other gasses.
Has liquid and frozen water.
Polar ice caps.
MARS
Called the red planet.
Fourth planet from the sun.
Most Earth-like planet in the Solar System.
Half the size of Earth.
Dry, rocky surface.
Very thin atmosphere
Carbon dioxide
Polar ice caps- frozen water and carbon
dioxide.
Large volcano- Olympus Mons
Two tiny moons- Phobos and Deimos
JUPITER
Fifth planet from the sun.
A gas giant.
It is so big that all the other
planets could fit inside
Jupiter.
Thick atmosphere.
Has a dark, barely-visible
ring.
Huge red spot is a longlasting storm.
Has 63 Moons
Ganymede is the largest
moon in Solar System.
SATURN
Sixth planet from the sun.
Gas giant.
Second biggest planet in the
Solar System.
Many beautiful rings made
mostly of ice chunks and rocks.
Saturn made of hydrogen and
helium gasses.
Visible without a telescope but
one is needed to see the rings.
Has 62 moons.
URANUS
Seventh planet from the sun.
Huge, icy planet covered with
clouds.
Encircled by a belt of 11 rings.
Blue color is caused by the methane
in it’s atmosphere. (absorbs red light.)
Rotates on its side (along its orbital
path.)
Tipped rotational axis gives rise to
extreme seasons.
Has 27 moons.
Appears to rotate clockwise.
NEPTUNE
8TH planet from the sun.
Giant, frigid, gas giant.
Hazy atmosphere and strong winds.
Narrow, faint rings.
Blue color is caused by methane in its
atmosphere.
Axis is tilted a little more than Earth’s.
Gives long-lasting seasons. The poles are
in constant darkness or sunlight for 40
years at a time.
Has 13 moons.
