FALCON FOCUS
• The news has just broke that Earth is going to
be destroyed in the next 2 months!! It is YOUR
job to find which planet humans need to
move to.
• Using what you know about the planets
already, decide: Which planet can we go to??
Why do you think that?
THE SOLAR SYSTEM
Magic School Bus
• Watch the video and fill out the front page of
your notes.
• For each planet, you must
1. List them in the correct order
2. Write one thing about that planet

Why does everything orbit the Sun?
• Everything in the Solar System revolves
around the Sun. Because the Sun is so large,
its powerful gravity attracts all the other
objects in the Solar System towards it. The
planets at the same time are trying to pull
away from the sun. What happens is that the
planets become trapped in between the
motions- balanced eternally orbiting around
the sun.
Explain: Planets
• An object in orbit around a star but does not
give off its own light, rather it shines by
reflecting sunlight.
• Inner Planets- Terrestrial (orbit close to the
sun): Mercury, Mars, Venus, Earth
• Outer Planets- Gaseous (orbit far from the
sun) :Jupiter, Saturn, Uranus, Neptune
Our Solar System
The Inner Planets
Terrestrial
• Type of surface: ROCKY
• Size: SMALLER
• Rings? NO.
Mercury- “My”
•
•
•
•
Closest to the Sun
Only 88 days to orbit
Many craters
Temperature extremes
– 400C during day, -180 at
night
• Basically no
atmosphere
Venus- “Very”
• Earth’s sister planet
• Morning and evening
star
• Thick atmosphere of
CO2 and Sulfur
• Longer day than year
• Spins opposite than
other planets
• Over 500C all the time
Earth- “Educated”
• Home sweet home
• Only planet with
sustained life
• Hydrosphere (water)
• Atmosphere made up
of N, O, CO2
• Comfy temps
Mars- “Mother”
• Frozen polar CO2 caps
• Smaller than Earth
• Slightly longer day and
year
• Very cold
• Largest mountain in
solar system
– Olympus Mons
• Thin atmosphere
Asteroid Belt
• Separates the inner and
outer planets
• Possibly an annihilated
planet
• Most asteroids hang
out here
Outer Planets
Gaseous
•
•
•
•
Surface: Not solid, just thick atmosphere
Size: Large
Rings: YES!
All have rings
Jupiter- “Just”
• Could hold 1300 Earths
• Almost big enough to be
a star
• 12 EY = 1 Jovian year
• 1 Jovian day = 12 EH
• Huge storms
– Great red spot “hurricane”
larger than Earth
• Some moons may have
water
Saturn- “Served”
• 29 years to orbit
• Large rings made of
ice and dust
• 10 hour day
• Possibly still forming
• Tilts itself
Uranus- “Us”
• Blue in color due to
methane gas
• 84 years to orbit
• Rotates sideways
• Very cold
– -250C
Neptune- “Nachos”
•
•
•
•
Methane atomosphere
164 years to orbit
-250c temps
30 times farther from
the sun than Earth
What happened to Pluto?
Pluto is now classified as a dwarf planet.
FYI
*Some planets have a unique surface
characteristic, for example color or an
atmospheric storm.
*Movement of planets is based on revolution
around the Sun and rotation on the planet’s
axis.
Moons
• Moons orbit (go around) planets
• NOT all planets have moons.
• Most moons are rocky and covered with
craters (big holes)
• Movement is caused by the planet they orbit.
Moons
• There are over 140 moons in the solar system
• Mercury and Venus do not have moons
• Jupiter has the most moons (62!!)
Asteroids
• Mostly rocky and orbit in the Asteroid Belt
(between Mars and Jupiter)
• Many different sizes and shapes
• Movement caused by their orbit around the
Sun.
Asteroids
• Some asteroids not in the asteroid belt can
cross Earth’s orbit;
Scientists monitor the positions of these
asteroids.
– Why??
Comets
• Comets have
1. Main body or head (ices of water, methane and
ammonia and dust)
2. Tail that gets larger as the comet orbits closer to
the Sun
-Tail always points away from the Sun.
*Comets have unique long, narrow elliptical
orbit.
Meteoroids
• Chunks of rock that move around in the solar
system.
• Called different things based on their location
and movement:
*Called a Meteor – if it burns up in a
planet’s atmosphere
*Called a Meteorite – if it strikes the
surface of a planet or moon
Exit Ticket
• After learning about the planets, which planet
would be the best to evacuate humans to?
• Give 2 reasons for your answer
– You may discuss as a group first
