Horizon directions

Horizon & Directions

  • When looking at sky, we may view ½ of universe!

  • The Horizon is line between ground and sky.

  • 4 directions along horizon – North, East, South & West. To learn, say Never Eat Salty Worms!

  • North is direction your shadow points in mid day.

  • East is about where sun rises each morning.

  • South is where sun is highest in sky (in mid day)

  • West is about where sun sets in late afternoon.


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 spins so the 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 1 pm in October, Noon in Nov. & Dec.

  • 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, stars show 1st.

  • By end of dusk, bright 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’s lighted shapes change as we see its lighted side; its dark side blends in with the night sky


This presentation

Half full moon shows craters

near its straight edge where

sun there is rising or setting.


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 in moon due to dark plains

  • Dark plains of hard lava, good to land there

  • Over 40 yrs. ago, 1st men walked on moon

  • Perhaps in 2020’s, manned fly arounds

  • 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 steady points at night

Bright steady points at night?

  • Even the nearest planets appear as * (points) as we see them with our eyes; for even these objects very far away (moon=1 unit). Venus 100x farther.

  • 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…

  • How to tell a planet from a star?

  • Planet always brighter Planet shines steady

  • Best Evening Planet this fall?

  • Venus Mars Jupiter Saturn

  • Which part of Big Dipper points to N.Star?

  • End of Scoop or Arch of Dipper’s Handle

  • Write down your answers

  • Answers: Planet shines steady, Jupiter, Scoop


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 our moon.

  • What keeps stars, planets floating in sky?

  • There’s no up/down in space. Earth floats too!


Fall 2011 moon schedule

Fall 2011 Moon Schedule

  • Early October: ½ even.moon 10/3 (craters)

  • Full moon 10/11; shrinks & goes into morn.

  • Early Nov.: ½ even. moon 11/2 (craters)

  • Full Moon 11/10; shrinks & seen in morn.

  • Early Dec.: ½ even. moon 12/2 (craters)

  • Full Moon 12/10 (highest 2011 full moon)


This presentation

When evening moon looks like a ‘D’,

the sun is rising along left edge,

lighting up the crater rims and mountains.

This ‘D’ moon allows you to see craters

& mountains with binoculars held steadily

or with a small telescope on tripod (better).

A week after the moon is full, you can see it

In the morning day sky, as a backwards ‘D’.

Even during the morning hours, you can see

the craters & mountains on moon with binocular

or a small telescope. Never look at SUN!
