  • Planetarium Schedule for 2010 School Yr.
horizon directions
Horizon & Directions
  • When looking at sky, we may view ½ of universe!
  • The Horizon is line between ground and sky.
  • Horizon has 4 directions – North, East, South & West. To learn, say Never Eat Salty Worms!
  • North is direction your shadow points in mid day.
  • Sun rises each morning to the right of East (ESE)
  • South is where sun is highest in sky (in mid day)
  • Sun sets each afternoon to the left of West (WSW)
why does sun rise set
Whydoes SunRise & Set?
  • For thousands of years, humans believed that sun & sky objects moved about Earth every day!
  • In the 1500’s, Copernicus proposed that the Earth itself was moving, not the sky objects!
  • Copernicus wrote that the Earth was spinning every day and orbiting the sun every year!
  • It took over a century until most were convinced that Copernicus was correct (thanks to Newton).
  • The Earth turns so sun seems to rise and set.
let s review these ideas
Let’s review these ideas
  • What is the line between ground & sky?
  • Is it Ground line? Horizon? Edge of sky?
  • In what direction are shadows in mid day?
  • Is it North? East? South? or West?
  • Why does sun seem to rise and set?
  • Because: Sun is moving? Earth is spinning?
  • Write down your answers for these questions.
  • Answers are: Horizon, North & Earth is spinning
how day sky works
How Day Sky Works
  • Sun, our day star is so bright that it lights up air, causing it to glow blue on a clear day.
  • As Earth turns, sun seems to rise in morning
  • Due to our turning, sun slowly rolls right.
  • Sun peaks mid day (12 noon for standard time)
  • Sun sets near direction West as we turn.
  • To find North, face where sun goes down and extend your right arm out, points North.
twilight or dusk
Twilight or Dusk?
  • When sun disappears from our view, the air overhead is still ‘seeing’ sun and glowing.
  • As we turn more away from sun, only very thin, very high air still lit & sky gets darker.
  • This time is twilight or dusk, lasts an hour.
  • During dusk, bright planets, bright stars show 1st.
  • By end of dusk, easily seen star groups seen.
  • Just as dusk after sunset, dawn before sunrise.
what about moon
What about Moon?
  • Our moon is a ball of rock that orbits Earth.
  • Moon ¼ as big as Earth; if Earth a regular globe (1 ft.wide), moon is a tennis ball.
  • If Earth is regular globe, moon is 30 ft.away
  • As moon orbits us, we see day & night sides
  • In evening, lighted side ‘grows’ for 12 days
  • Then moon is full, shining all thru the night
  • Then in morning sky, moon ‘shrinks’ for 12 days
  • Moon seems to change shape, can’t see night side
just a little bit more about moon
Just a little bit more about Moon
  • The moon NOT a big cheese ball! (Sorry!)
  • Man/lady/rabbit at full moon by dark plains
  • Dark plains of hard lava, good to land there
  • Over 40 yrs. ago, 1st men walked on moon
  • Perhaps in 2020’s, more moon landings
  • Current rockets can’t carry people, new rockets needed, U.S., China or Russia to try
another review of ideas
Another review of ideas..
  • As you face sunset, what points North?
  • Back of Head? Right arm (out)? Left ear?
  • If Earth 1 ft. wide, how far away is moon?
  • Is it 10 feet? 30 feet? 100 feet? 300 feet?
  • How long does moon ‘grow’ or ‘shrink’?
  • Is it A week? A dozen days? A month?
  • Write down your answers to above 3 questions.
  • Answers: Right arm (out), 30 feet, Dozen days
bright points we see at night
Bright points we see at night?
  • Even the nearest planets appear as * (points) as we see them with our eyes; for even these objects very far away (if moon dist.=1, Venus dist.= 100)
  • To tell a planet from a star, all night stars twinkle and planets usually shine steady.
  • Also satellites (especially Space Station) shine steadily as creep eastward across sky
  • Night stars are distant suns, really, really far away compared to our planet neighbors.
  • If Earth penny size, moon 22” away, sun 730 ft. away (6.3 ft. wide), nearest star is 37,000 mi.away

let s review once more
Let’s review once more…

frequently asked questions
Frequently asked questions
  • What are falling stars? (Aka shooting stars)
  • Nearly all are pea sized space grit burning up in our upper atmosphere. Only dust left.
  • Can the planets line up like beads on string?
  • No, orbits are tilted but even if they could, pull is extremely weak, compared to moon.
  • What keeps stars, planets floating in sky?
  • There’s no up/down in space. Earth floats too!
