The Trippensee Planetarium is a demonstration model of the movement of the earth, moon and Venus relative to each other and to the sun.\u00a0 It shows such phenomena as the succession of seasons, and solar and lunar eclipses.\u00a0 In addition to its educational objective, the tellurian is also decorative and entertaining.\u00a0The original models, patented in 1908, have maple arms and central standards. Those produced around the second quarter of the 20th century have ebonized arms and central standards.\u00a0 Models made after World War II models are of Bakelite or plastic.<\/p>\n
