In 1801, a young mathematician stunned the scientific world by using the modest mathematical tools of algebra and trigonometry to solve the complex problem of calculating planetary orbits. He explains his methods in this volume, which is suitable for upper-level undergraduates and graduate students and remains a vital reference in modern astronomical computation and celestial mechanics. Unabridged republication of the edition published by Little, Brown and Company, 1857.
