A lighted model of the world’s most widely used planetarium. It shows synchronized motions of Venus, Earth, moon, and sun, and other planetary phenomena, including all the important Earth, moon, sun relationships. The light is used to graphically illustrate lunar, solar, and annular eclipses, phases of the moon, and areas of day, night, and twilight. With a minimum of care, this Trippensee® Planetarium will give 20, 30, or more years of trouble free service as thousands already have.
