What is recorded here?
Used astronomical observations to describe elliptical orbits and equal-area motion, followed by a relation between orbital periods and sizes.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
1609 dates the first two laws; the third appeared in 1619. Tycho Brahe’s observations were a crucial precursor and are identified separately.
