Cut a 4 foot piece of 2” wide
register tape
Write “
SUN
” at one end and “
PLUTO/KUIPER BELT
” on the other end
This is the point where “things” get interesting
A Pocket Solar SystemSlide5
Fold the strip in half
Which Planet do you think is halfway between the
SUN
and
PLUTO
?
Hold the strip at arms
length with your back facing the group…what body part is near the fold?
Older folks may feel embarrassed but the kids will giggle !
A Pocket Solar SystemSlide6
URANUS
Pronounced: YUR an us
Write
URANUS
on the first fold
Are you SURPRISED? Most times, the Planets are depicted being close together but they certainly are NOT!
Fold the
SUN
to
PLUTO
again…(in half)
Fold the strip in half again…(in quarters)
A Pocket Solar SystemSlide7
At this point, it’s easy to figure where
NEPTUNE goes…between URANUS
and
PLUTO
Which Planet do you think is halfway between the
SUN
and
URANUS
?
Is it
JUPITER
or SATURN?

SATURN
Fold the
SUN
to
SATURN
This next fold is
GIANT JUPITER
A Pocket Solar SystemSlide10
Fold the
SUN to JUPITER
Which do you think is halfway between the
SUN
and
JUPITER
?
Is it
MARS
?

The
ASTEROID BELT…write this on the fold.
Fold the
SUN
to the
ASTEROID BELT
…
What Planet falls on this fold?
Is it
MARS
?
You guessed right BUT…now we need to get the last three planets between
MARS
and the
SUN
A Pocket Solar SystemSlide12
Fold the
SUN to MARS
Fold it in half again
Write the last three Planets on their respective
lines, from the
SUN
: (OK to use Initial)
MERCURY = M
VENUS = V
EARTH = E

Use the following chart and write the AU, Astronomical Unit, next to each Planet
Note the average distance from the SUN to
EARTH
is 93 million miles or, 1 AU.
The inferior “rock” Planets are less than 1 AU and the superior “Gas Giants” are more than 1AU
PLUTO
is now around 40 AU but circles the
SUN
between 30 and 50 AU in its’ 248 year orbit

At this scale, our 4 foot
SOLAR SYSTEM would be 6 MILES from the next closest STAR, Alpha Centauri, 4.2 Light Years from our SUN
or almost 64,000 AU’s.
One LIGHT YEAR is approx. 6,000,000,000,000
miles (Tr.)
Our
SUN
would be a tiny speck in space…the size of the period at the end of this sentence.
Our planets wouldn’t even be visible from this
distanceNow you know why SPACE is called “SPACE”
