Slide4Cut a 4 foot piece of 2” wide register tapeWrite “SUN” at one end and “PLUTO/KUIPER BELT” on the other endThis is the point where “things” get interesting

Slide5Fold the strip in halfWhich 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 !

Slide6URANUSPronounced: YUR an us Write URANUS on the first foldAre 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)

Slide7At this point, it’s easy to figure where NEPTUNE goes…between URANUS and PLUTOWhich Planet do you think is halfway between the SUN and URANUS?Is it JUPITER or SATURN?

Slide10Fold the SUN to JUPITERWhich do you think is halfway between the SUN and JUPITER?Is it MARS?

Slide11The 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

Slide12Fold the SUN to MARSFold it in half againWrite the last three Planets on their respective lines, from the SUN: (OK to use Initial)MERCURY = MVENUS = VEARTH = ESee next slide

Slide13Slide14Use the following chart and write the AU, Astronomical Unit, next to each PlanetNote 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 1AUPLUTO is now around 40 AU but circles the SUN between 30 and 50 AU in its’ 248 year orbit

Slide16At 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”
