1975 Hallwag Map of the Solar System

The orbits of the planets and comets.

This is a 1970/1976/1977 Hallwag map of the Solar System. THe Sun appears just below center, and yellow lines trace the orbit of the planets, including Pluto. Pluto and Neptune's orbits are so large that both extend off the bottom of the sheet. All planets are labeled in German, English, French, and Italian. Thin gray lines surrounding each indicate moons. Red lines highlight the orbits of numerous comets, all of which are identified. A diagram in the lower right provides a visual representation of the size of the Sun relative to the size of each planet. Color renderings of Mars, Jupiter, and Saturn are situated in the upper left. Information concerning the map's scale, notations used, and the statement that the planets' positions were taken on January 1, 1976, appear along the bottom border.

Verso Content

Educational content abounds on the verso. Diagrams of historical models of the Solar System, the orbit of the Earth around the Sun, and Solar and Lunar Eclipses appear in the upper left. A diagram depicting the Sun's ecliptic through the sky as seen from Earth dominates the upper border, while short paragraphs about each planet occupy the upper right. Information about the orbits of the moons of Earth, Mars, Jupiter, Saturn, Uranus, and Neptune appear in the bottom third of the sheet, along with a section about comets and another discussing space exploration vehicles.
