His observations were some five times more accurate than the best available observations at the time. An heir to several of Denmark's principal noble families, he received

Although Tycho's planetary model was soon discredited, his astronomical observations were an essential contribution to the scientific revolution. The traditional view of Tycho is that he was primarily an empiricist who set new standards for precise and objective measurements. This appraisal originated in Pierre Gassendi's 1654 biography, "Tychonis Brahe, equitis Dani, astronomorum coryphaei, vita".
