Some words to know before we continue
• Gravity- force that attracts you or anything to
an object with greater mass
• Dwarf planet- is a similar to a planet, but is
technically too small to be considered one
• Orbit-the curved path of a celestial object or
spacecraft around a star, planet, or moon
• Atmosphere- the area of gases surrounding
the earth or another planet
• Star- is a massive, bright sphere of gases held
together by its own gravity
Our galaxy
• We live in a galaxy called the milky way
• A galaxy is a group of stars and other space
stuff (dust, gases, planets)
• The stars tend to spin around a center of high
gravity, sort of like the planets spin around the
Sun in the Solar System
• Galaxies are huge and can have trillions (way
bigger than billions!) of stars
Neptune
The planets
Uranus
Saturn
Jupiter
Mars
Earth
Venus
Mercury
The sun
Poor Pluto
The
Sun
• The Sun is a star that is in
the center of the Solar
System
• Our sun is 5 BILLION
years old!
• It was once just a big area
of gas and dust that was
condensed by gravity
• The Sun’s distance from
the Earth is 150 million
km (93 million miles)
Mercury
• On Mercury you weigh only 38% of
what you weigh on Earth.
• One side of the planet can be 800
degrees Fahrenheit when the other
can be -280 degree Fahrenheit at
the same time.
• Fastest orbiting planet
• Planet nearest to the sun
Venus
• Is the cloudy planet
• Venus has tons of volcanos just like
earth
• Rotates in the opposite direction of
Earth
• Venus is the hottest planet in the
Solar System
Earth
• The only known planet to have
life
• The Earth is an oldie but a
goodie, scientists think that
Earth is about 4.5 to 5 billion
years old!
• About 70% of earth is water
• Approximately 90% of volcanic
action happens in our Earth's
oceans!
• Mars is nicknamed the red
planet
• It is covered with rust-like dust
even the atmosphere is a
pinkish red
• Mars has many massive
volcanoes and is home to
Olympus Mons, the largest
volcano in our solar system
• Unfortunately Mars has no life
as we know it so…no aliens
Mars
Jupiter
• Largest planet in the Solar
System
• Has a Great Red Spot from a
storm system that is more
than 400 years old
• 9 hours and 54 min=1 Jupiter
day (shortest day)
• Pressure is so great it would
crush a spaceship.
Saturn
• 2nd Largest planet in the
Solar System
• 95 times more massive than
earth.
• Saturn has the largest rings
of any planet, the rings are
made of icy particles and
dust
• Most moons of any planet in
our solar system
Uranus
• Uranus appears blue-green in
•
•
•
•
color
It’s axis of rotation is tilted 90
degree
Uranus has 27 moons
If you weigh 100 lbs on earth,
your weight on Uranus would be
89 lbs
A year on Uranus is equal to 84.01
Earth Years
Neptune
• Neptune has visual belts of clouds
• Just like Jupiter it has storms happening all
around the planet
• It has a dark blue spot
• Neptune is the farthest planet from the Sun
Pluto the dwarf planet
• It is considered too small to
be a planet so it was put in
the dwarf planet category
• Smaller than Earth’s Moon
• If you weigh 100 lbs, your
weight on Pluto would be 7
lbs!!!
• Since being declassified as
a planet, Pluto’s technical
name is now 134340
