2 What Do You Know We hope you have enjoyed learning about astronoy using your Horizon Globe. If you have done and understood the exercises in this book, you know ore about observational astronoy than ost people, even soe who know a lot about deepspace astronoy. Enjoy your new knowledge of the sky. There is great joy to be had fro the basics of astronoy. You don t need telescopes or sky aps to enjoy these things on a daily basis. There is always soething fun to watch, the sun changing through the seasons, the onthly oon cycle, nightly stars and planets. You can tell tie by the un. Any tie you see the un, you can notice how its position relates to the tie of day. At night you can estiate how far below the horizon the un ust be. Noticing where the un rises and sets and which direction it is highest at noon can help you find directions. Enjoy noticing how the direction of sunrise and sunset relate to the day of the year. oon watching will never be the sae. You know the oon follows the un, but is lazy and falls behind by alost an hour per day. Notice how the angle between the un and oon deterine the shape, or phase of the oon. It s fun to see the oon and know where it will be toorrow. But that s not all. Any tie you see the oon you can try to iagine where it is on the ecliptic. It ay be uch farther north or south than the un, or it ay be the sae. Don t try to explain it to your friends without a Horizon Globe! When the un goes down, watch for planets. Is enus out? In the evening or in the orning? upiter shines bright on ost nights, but check the calendar, he ay not appear until the wee hours of the orning. Try finding aturn. Are you sure it s not a star? When ars gets super bright for a few onths every two years, you will know what is going on. Any tie you see stars in the sky, feel the confidence of knowing at least one iportant constellation, whichever guidepost is high. You know the significance of the Zodiac and their order on the ecliptic. Tell your friends what akes the a Leo or a corpio! On the following page is a suary of soe of the things we ve covered in this book. In the next installent of the series we ll talk ore about constellations and great ways to reeber how to find the. tay tuned!

3 Astronoy copels the soul to look upwards and leads us fro this world to another. -Plato The un How to tell tie by the sun How to talk about where celestial bodies are: angles, hours The oon Full oon is opposite the sun Crescent oons are near the sun Quarter oons are 0 degrees fro un Gibbous oons are far fro un, but not yet full Waxing and Waning oons How to use a oon Calendar to find the current Phase How to ap the ecliptic by watching the oon Constellations How to find a guidepost constellation. How to find Orion, day or night Zodiac constellations, naes and locations Planets Which planets are easily visible: enus, ars, upiter, aturn How the otion of enus differs fro the rest How to use the oon and Planet Calendars to find any Planet easons What causes seasons How to avoid sunburn How the oon changes with seasons Everything in the sky akes one coplete turn every day The un, oon, and Planets travel on the ecliptic Over longer periods of tie, we can notice things oving at different speeds: Object un oon tars (Orion) aturn upiter ars peed akes one turn in hours or day Lazy. Lapped by the un every 0 days Laps the un in year Laps the un in year, weeks Laps the un in year, onth Laps the un in years, onths

4 What s Next? If you have learned the contents of this book you have an excellent foundation in basic astronoy. At this point you ay be surprised at what was not in this book. We did not talk about planets going around the un, or about galaxies or black holes. We purposely left those things out. A proper start in astronoy requires that you know the basic workings of the sky: the daily turning and the coplexity caused by the angled plane of the ecliptic. All ore advanced study of astronoy depends on this. Hopefully, after studying the aterial in this book you are eager to learn ore. Here is what we recoend to do next: Learn the shapes of the ajor constellations and how to find the. Your Horizon Globe gives you the general layout of the sky and how it oves, but actually finding stars and constellations is another skill.

5 Work hard to find soething that fascinates you. When you find it, you will know your lifework. -Richard P. Feynan Horizon Globe will be publishing a guide to finding stars and constellations in. In the eantie we have two books to recoend that we think are the best resources out there for stargazing. The tars: A New Way to ee The, by H.A. Rey This book was a ajor influence on getting us into astronoy and showing us how to do it. It akes a great sky encyclopedia, but does not offer a guidepost-type way to systeatically learn the constellations. The tars: Learn the Bright tars and Iportant Constellations by To andae and David Harrian This book is available through Aazon. It outlines an easy way to learn the ajor constellations based on the Guidepost syste. We believe the book shows a great way to learn the stars and constellations, but the production quality ay interfere with ease of use. If you wish to advance into applying ath to astronoy, Falling Apple cience Institute has published two ore books that show step-bystep how to easure the Earth, understand sundials, easure the sky, understand and predict solar and lunar eclipses, and other atheatical astronoy. Early Astronoical easureent I by To andae and David Harrian Early Astronoical easureent II To andae and David Harrian both of these books are available through Aazon.

6 oon and Planet Calendars -0 The oon and Planet Calendars are easy to use. Place the un on your Horizon Globe on the day of interest and turn the un to noon. Check the date to find the oon phase. Hold the calendar over the North Pole and place each planet according to its clock position. Use the Zodiac, Guideposts, olstice and Equinox lines to confir positioning. The oon and Planet Calendars provide a snapshot of where the planets are on the st of each onth. We chose the st to align with the olstices and Equinoxes. Of course the planets don t jup fro onth to onth, they ove continuously. For greater accuracy, use the adjacent onths to interpolate planet positions. Year tart by finding the year of interest Year is listed at the top of the page onth Next, find the onth of interest ul onth is in the center of the circles Day & Hour Place the un on your Horizon Globe on the day of interest. Turn it to noon. ul The un is always shown at noon on the ecliptic ring. You are looking down at the Ecliptic Ring fro the North Pole. oon Phase Find the phase of the oon for the day of interest. Interpolate to find the dates of Crescent and Gibbous oons. (see page 0). ul oon phases. New oon near the un, Full oon opposite. Nubers indicate the date of each phase. 0

7 Planets Planets are shown as colored circles with letters inside. As you look down fro the North Pole, place each planet in its clock position fro the noon un. upiter ars aturn ercury enus ul If a planet sees to be issing, it ay be covered up, or occulted, by another planet. Check adjacent onths to confir. Zodiac Notice that the Zodiac constellations are shown for reference. You don t need a chart to know where these are, they are the sae every year. ul Zodiac constellations in order. olstice and Equinox The straight lines ark the olstices and Equinoxes. They are not labeled, but you can tell which is which by the onth and the Zodiac. ul olstices Equinoxes olstice and Equinox lines rotate fro onth to onth along with the Zodiac. Guidepost Constellations Guidepost Constellations are included for reference. Only the clock position of these is correct, they are north or south of the ecliptic. ul Guideposts Reeber the Guidepost story: The Dipper stalks Orion. Cygnus flies to the Dipper. The Queen chases Cygnus. Orion pursues Cassiopeia.
