The book impressed the most impressive astronomer of the day, Tycho Brahe, and two men began what quickly became a tempestuous collaboration. Brahe had accumulated 20 years of precise observations and needed someone with Kepler's mathematical prowess to make sense of it. Kepler promised he could solve the orbit of Mars within 8 days. Mars was particularly difficult because the observations varied from Tycho's calculations more than any of the planets. Instead, the task took nearly about 8 years and more than 900 pages of calculations before he wrapped it up.Johannes Kepler's last work, Somnium ("The Dream") was
