Sky to Space: Astronomy Beyond the Basics with Comparisons, Ratios and
...gets you started as a space explorer. This book shows you how to follow the clockwork motions of Earth’s sky, then how to predict what you would see from our moon, other planets and moons in our solar system and other solar systems.
You’ll get scientifically accurate results using pencil, paper and easier-than you-think math. An extensive chapter on eclipses explains the movements of the moon and its shadow and shows you how to predict eclipses using the Saros cycle. Additional moon chapters include “Giant Moon,” “Red Moon” and “Why Does the Moon Seem to Follow Your Car?”
This book contains many project ideas. With a pencil, a ruler, and two coins, accurately draw the phase (crescent, quarter, or gibbous) of any moon or planet as seen from anywhere in a solar system. Figure out how far you must fly from Earth for our home planet to appear as a point of light. Use real data to predict how big one of the TRAPPIST-1 exoplanets would appear in the sky of one of its neighbors.
Science students looking for project topics, homeschool and unschool families, amateur astronomers and model rocket flyers, lifelong learners and space cadets of all ages will find exciting new ideas in this book.
Sky to Space has over 100 pages of intriguing information and project ideas, plus two handy pages of frequently-needed data on sizes and orbits of planets and moons in our solar system.
