•
small planet
4th planet from Sun
orbit is mild ellipse or stretched circle
named after the Roman god of war
year is 687 Earth days
day is 24 hr. and 37 min.
diameter 6800 km.
Can be seen without a telescope—a small rust
colored light in the sky
Mars
•
•
•
•
•
core of iron
thick rock layer above core
atmosphere thinner than Earth’s
has dust storms and clouds
entire planet can be covered by storms and
dust at once
• average temp. -12 degrees C
• winter can get to -70 degrees C
Mars
• In winter, the planet has ice caps at the north and
south poles like Earth does.
• caps are made of frozen carbon dioxide, or “dry ice”.
• has mountains, sandy deserts and many, inactive
volcanoes.
• largest volcano in the solar system- Olympus Moonsover 133000 m. tall, much higher than Mount Everest,
and is over 965 km. wide at its base.
• many canyons -Valles Marineris- over 3200 km. long
and deep enough to hold a mountain range.
Mars
• two moons- Phobos and Deimos
• Moon actually asteroids that got caught in
Mars’ gravitational pull

Mars.

Answer: Phobos and Deimos
Week 3 Day 2
Jupiter
• 5th planet from the Sun
• It is called a gas giant because it has no solid
ground to land on.
• The largest planet in our solar system
• Its orbit is nearly circular.
• Jupiter was named after the king of the Roman
gods. (Greek name Zeus, English name Jove)
• One year on Jupiter =almost 12 Earth years
• One day on Jupiter=10 hours
Jupiter
• For size comparison, if Earth was a dime….Jupiter would
be a soccer ball!
• Jupiter can be seen without telescope
• Jupiter is a giant cloud made up mostly of hydrogen and
helium.
• Gravity holds this ball of gas together.
• It does not have surface/solid ground since it is gas.
• Constant swirling of gas creates wind storms—Great Red
Spot.
• At least 63 known moons; 4 large moons revolving
around it.
Jupiter
• 4 largest moons—Io, Europa , Ganymede,
Callisto
• Io- closest moon to Jupiter. Its colorful orange
and yellow surface is caused by volcanoes.
• Europa is a giant ball of ice.
• Ganymede, the largest moon, is made up of
rocky ice.
• Callisto is covered with thousands of craters
and farthest from Jupiter.

a gas giant
6th planet from the Sun
Named after the Roman god of agriculture

Saturn day=10 ½ hr.
2nd largest planet
Can be seen without telescope
Has faint greenish color
Saturn

•
mostly hydrogen and helium
less dense than Jupiter
no solid surface
center=liquid hydrogen
Has more than 60 moons
Saturn’s largest moon isTitan
The ONLY moon in the solar system that has a thick
atmosphere and clouds.
• Titan may have liquid water on surface (liquid methane)
Saturn
Special Features
• The Rings
Very thin
• seem to disappear when Saturn is viewed from the
edge
made up of billions of pieces of rock and ice, ranging
from the size of a grain of sand to the size of a car.
• The gaps in Saturn’s rings are caused by the many
moons that circle the giant planet. The moons keep the
rings lined up.
• One of the bands in Saturn’s rings is braided, much like
a pigtail.
Saturn
Special Feature
• Weight
weighs very little
very light gas planet
so light that it could float in water.
