The Planisphere of Tycho Brahe, plate 6 from Harmonia Macrocosmica, 1660, Andreas Cellarius; Publisher: Johannes Janssonius, German (active in the Netherlands), German (active in the Netherlands), c. 1596 - 1665, 17 3/8 x 20 7/8 in. (44.13 x 53.02 cm) (image, margins trimmed), Hand-colored engraving, Netherlands, 17th century, The Danish astronomer Tycho Brahe (1546-1601) devised this complex geo-heliocentric model, which has the Sun and Moon revolving around the Earth, and the other planets orbiting the Sun. This reflected a compromise between the systems of Ptolemy and Copernicus by permitting the Earth to remain immobile at the center of the universe but accounting for some of the newly recorded observations on how the planets moved. Despite its problems (namely the intersecting orbits of Mars and the Sun), Tycho's hybrid system was favored during most of the 17th century.
