Mercury
Messenger of
Roman Gods.
Not much larger than OUR
moon; 8th smallest.
Atmosphere composed of
helium and sodium, renewable.
Has a large iron core;
magnetic field strength 1% of
Earth’s.
Surface temperatures range
from - 183 0C to 427 0C.
VENUS
Orbit is most circular
compared to the others.
Rotates clockwise on
its axis.
#2
Atmosphere is
composed mostly of
carbon dioxide.
goddess of love and
beauty, springtime and
flowers.
Several layers of
sulfuric acid clouds.
Many kilometers
thick.
Surface temps are
hotter than those on
Mercury.
Population: 6,446,131,400
(July 2005 est., CIA world fact
book.)
Chemical composition is
mainly composed of: Iron,
Oxygen, Silicon, Magnesium,
Nickel, Sulfur, and Titanium.
Has one natural satellite; THE
MOON!!
It was in the 1500’s that
scientists finally recognized that
Earth was also planet.
Atmosphere is 77% nitrogen,
21% oxygen, with traces of
argon, carbon dioxide and water.
Only planet that has “plate tectonics.”
Mars is much smaller than
Earth.
Home of Olympus Mons;
24km (78,000 ft.) high.
Satellites: Phobos and
Deimos
Thin atmosphere composed
mostly of carbon dioxide,
nitrogen, argon, and traces of
water and oxygen.
Very strong winds and vast
dust storms.
Roman God
of war.
Permanent ice caps at both
poles.
By far the largest planet;
diameter 142,984 km
(equatorial)
Four large moons Io,
Europa, Ganymede and
Callisto; the Galilean moons.
Atmosphere has hydrogen,
helium and traces of methane,
water, ammonia and "rock".
As a gas giant has no solid
surface.
Radiates more energy into
space than it receives from the
Sun.

earth. 7 total.

Some of Saturn’s
satellite (moons) help
keep the particle rings
in orbit.
Saturn has 34
named satellites.
Telesto
Father of Saturn
and grandfather
of Jupiter .
Name is pronounced:
YOOR-a-nus.
Atmosphere is composed of
hydrogen, helium and
methane.
Rotates on an axis that is
parallel to its elliptical path.
Still is hotter at its equator
than at its poles.
Overlying Methane layer,
causes blue color
Roman god
of the sea .
Found while researching
a disturbance in Uranus’
orbit.
Planetary winds are the
fastest in the solar system.
Neptune can be seen
with binoculars.
13 known moons.
Has 4 rings of unknown
composition.
Is sometimes the most
distant planet for a few
years.
PLUTO
Smaller than seven of the
moons in the solar system.
Only planet that has not been
visited by a spacecraft.
It’s orbit is highly eccentric
Surface temperatures vary
between about -235 and
-210 C.
#9
Rotates in the opposite
direction of it’s orbit, retrograde.
One named moon, Charon,
and two newly discovered tiny
satellites.
Greek god of
wealth, ruled
the dark
underworld.
Recently discovered.
Almost certainly larger
than Pluto.
An estimated 97 times
further from the sun than
the Earth.
Our Sun
Most distant object ever
seen in orbit around the
sun.
Takes more than twice as
long to orbit the sun as
Pluto.
