Compare the size of the Sun
to all 8 Planets!
Pluto/dwarf planets:
► Considered
a dwarf planet
► There are over 50 similar objects in the
solar system – too many to call them all
planets
► Pluto has a moon which is more than half its
size
► Orbit is so elliptical that it’s path is inside
Neptune’s for 20 years
Asteroids
► Large
rocky bodies that revolve around the
sun in an orbit between Mars and Jupiter
► Thought to be left over pieces from the
early formation of the solar system that
were not massive enough to form into a
planet
meteoroid
► Small
rocks that revolve around the sun in
random orbits throughout the solar system
► Meteor
– rock burning in our atmosphere
“shooting star”
► Meteorite
– a rock from space that has hit
the Earth’s surface
 (a meteor “rite” here on the ground)
comet
► Small
dust
► Has
object made of frozen gas, ice and
a highly elliptical orbit
► Often
called a “dirty snowball”
► Meteor
showers happen when we travel
through the debris of a comet’s dirty orbit
