Inner Planets – Part 1
There are 8 planets within our solar
system. The inner planets are
Mercury, Venus, Earth, Mars, with
Mercury being closest to the sun and
Mars being the farthest. These
planets are known as terrestrial
planets. That means that they are
like the Earth in some ways.
The term terrestrial can be
misleading because each of the four
planets has vastly different
environments. The inner planets all
have rocky outer cores, made up
mostly of heavy metals such as iron
and nickel. These planets have either
no moons or few moons. A moon is a
celestial object that orbits (moved
repeatedly around) a planet.
Mercury and Venus are so close to the
sun that the sun's gravity is too strong
for them to have their own moon.
Earth has one moon, and Mars has
two. The moons that orbit Mars are
the smallest in the solar system.
The atmosphere of the terrestrial
planets ranges in thickness and in
composition. The atmosphere of a
planet is made up of gases that
surround it. They have changed as a
result of sunlight (which produces
chemical reactions, such as those that
break apart water molecules), escape
of light gases, volcanic activity, and in
the case of our planet, biological
activity.

Inner Planets – Part 2
Mercury has almost no atmosphere,
while Venus is thick with carbon
dioxide. The surface temperature of
Venus is approximately 465 degrees
Celsius! Compare that to Earth’s
surface average of only 15 degrees
Celsius!
The atmosphere of Mars is thin
compared to that of Earth, Mars’
atmosphere contains mostly carbon
dioxide, while Earth is primarily
Oxygen and Nitrogen. Scientists
have found evidence that there may
have been once water on the planet,
and with water, could there have
been life? Perhaps one day, we will

Continue to Part 2
Outer Planets – Part 1
In the outer Solar System are the
four remaining planets Jupiter,
Saturn, Uranus, and Neptune. The
inner and outer planets are separated
by the asteroid belt.
The outer planets are made primarily
of gasses. These planets are called
Jovian planets or gas giants. They
are massive and consist of a thick
atmosphere and a dense molten core.
Because the gas giants aren't made
of rock and solid matter, they don't
have solid surfaces like the terrestrial
planets. Therefore, landing on one
would be impossible.
The outer planets have similar
characteristics to one another. The
outer planets are so much larger than
the inner planets that they make up
99 percent of the mass of the celestial
bodies that orbit the Sun.
Although mainly composed of gas, the
outer planets also have other
ingredients. Somewhere at the center
is what scientists refer to as a rocky
core. This core is actually composed
of liquid heavy metals. While the inner
planets have few or no moons, the
outer planets have dozens each.

ammonia clouds
Jupiter and Saturn have
cloud layers that form at
an atmospheric
temperature of about 150
K or -124 degrees Celsius
cloud layers
The distinct cloud
layers altitudes are
dictated by the
atmospheric levels at
which various gases
can condense into
liquid droplets or solid
flakes.
Continue to Questions
Outer Planets – Part 2
The atmospheric structures of the
four Jovian planets are all quite
similar. The primary difference is
that the atmospheres get
progressively cooler with increasing
distance from the Sun. Clouds of a
certain composition always occur at
about the same temperature. For
example, the ammonia clouds on
both Jupiter and Saturn form at an
atmospheric temperature of about
150 K (or -124 degrees Celsius.)
This happens to be around 25 km
below the cloud top on Jupiter and
100 km below the cloud top on
Saturn.
Each Jovian planet has distinct
cloud layers, with altitudes dictated
by the atmospheric levels at which
various gases can condense into
liquid droplets or solid flakes.

How is distance measured?
●
Because of the ENORMOUS distances between objects in space, we use the
A.U. or ASTRONOMICAL UNIT as our measuring tool for space
●
An Astronomical Unit (A.U.) = the average distance from Earth to the sun about 150 million km (93 million miles)
