A Plan or Map of the Solar System Projected for Schools & Academies

Colby, Hall

1846

A chart of the solar system created for New York state schools and presented to the Library of Congress in October of 1846. Predating Leverrier's hypothesis, Colby was likely influenced by the French astronomer Jacques Babinet, who had made related conjectures the same year as this chart.
