H152 ORBITER (LIGHTED SUN) 12VOLT VERSION US$269.95

These Orbiters are scientific working models representing the Sun, Earth and Moon and their relationships. They demonstrate basic earth and moon motions, the causes of day and night, seasons and phases of the moon. The orbiters are scaled to show relative sizes, distances and motions of the earth. The earth and moon, however, are shown in true scale (1 inch = 2000 miles). The illustrated lesson plan booklet covers: Earth’s rotation, earth’s revolution and tilt, length of day and night, phases of the moon, why we see only one side of the moon, sun and moon eclipses, explanation of tides and much more.
