ALL THE PLANETS REVOLVE AROUND THE SUN.
THEY ARE SATELITES OF THE SUN

THE PLANETS ARE NOT ALL THE
SAME
They differ in:
COLOR
SIZE
POSITION
SHAPE
LAYERS
SATELLITES
WEATHER
GASES
ATMOSPHERE
ROTATION REVOLUTION
TILT
MERCURY
Now that Pluto is gone it is the
smallest planet
Named after Mercury the swift
messenger of the Roman Gods
Very thin atmosphere or no
atmosphere, so humans could not
live there
Takes 88 days to revolve or orbit
around the sun
The length of a day is 59 of Earth’s
days
No water
Temperature range is -292 F to 842 F
depending in if it is day or night
No natural satellites or moons
Mariner probe discovered its surface
is similar to our moon
VENUS
Almost as big as Earth-called our twin
Has a hostile atmosphere full of
carbon dioxide gas that traps heat
Venus gets so hot during its day that
it metal would melt like ice cream
(869 F)
Has thick rapidly spinning clouds that
hold heat in and reflect light back
making it look like a star in the sky
Constant thunderstorms
Rotates in the opposite direction of all
the other planets
Named after the Roman goddess of
love and beauty
Takes 225 days to revolve around the
Sun
A day on Venus is 243 Earth days
long
No water or satellites
EARTH
Has an atmosphere full
of nitrogen and
oxygen so we can
breathe
Has liquid water
Has life in the form of
plants and animals
Temperature is cold and it has polar
ice caps like Earth which may
contain water
The iron in the red clay dirt is what
makes it look red
Last if the inner planets
Similar to Earth in length of day
(24hrs7min), types seasons and
tilt
It takes 687 days to make a year on
Mars
Seventh largest
Dry planet with thin atmosphere made
of carbon dioxide.
Named after the Roman god of war:
Mars because it appears red and
angry
Two satellites: Phobos (fear) and
Deimos (panic) companions to
war god
No life discovered on planet but
scientists are hopeful there are
microscopic life forms inside the
rocks or ice caps that they might
discover
Has strong winds and seasons
MARS
JUPITER
Largest Planet-1000 Earths could fit
inside Jupiter
Its clouds in its atmosphere change
color daily due to hydrogen and
helium gas changes
Red spot is swirling gas moving due
to a very long hurricane
Has lightning
Has two rings
No water, but oceans of liquid
hydrogen
Rotates quickly-every 10 hours (Earth
rotates once every 24 hours)
Takes 12 years to revolve around the
sun
Has over 60 satellites (63)
Named after the chief, supreme
Roman God similar to the Greek
God Zeus who it was originally
named after
No life
Average temperature is -302F
SATURN
Second Largest
Has a thin atmosphere that contains
bands of clouds made up of
helium and hydrogen
The thousands of rings are made up
of ice, rocks and particles of dust
that orbit the planet
30 or more satellites named for the
Titans
Takes 30 years to revolve around the
sun
A day is 11 hours long on Saturn
because that is how long it takes
to rotate fully
Water??? Probably not
Life??? Probably not
Named for the Roman God of
agriculture who is also the father
of Jupiter
URANUS
It was discovered later than the
others, 1781 and discovered
by telescope not sight
Has an atmosphere of hydrogen,
helium and methane gas that
gives it the blue-green color
Water??? Probably not
Life????? Maybe not
Scientists believe it collided with
another planet once which
caused it to have a completely
tilted axis.
Has 11 rings made up of rocky
chunks
Day = 17 hours (rotation)
Year = 84 Years (revolution)
Named after Greek god of the sky
Does not have a regular orbit.
AXIS
NEPTUNE
Not discovered until 1946 by telescope
Scientists believe Neptune’s gravity is
what pulls Uranus out of a regular
orbit
Named for the Roman god of the sea
because of its color
Also made up of hydrogen and helium
and some methane to cause the
blue color
Neptune rotates (day) fully in 16 hours,
but its atmosphere and clouds take
two hours longer. That is unique.
Has dark colored storms, one the size
of Earth and is the windiest planet in
solar system
Takes 165 years to revolve or make a
year
Neptune is thought to have a layer of
liquid water, methane and ammonia
that changes to solid ice at times.
Has 8 satellites and 4 rings
