Edmond Halley of Halley's Comet fame became Astronomer Royal in 1719. An
admirer of Newton he was instrumental in getting the Principia into print. These
posthumously published tables are important for the manner in which they employed
Newton's rules for calculating the position of the moon and Flamsteed's planetary
observations. The planetary tables continued to be in use until the 1790s.
This particular table shows conjuctions between the moon with the sun for the period
in question.
F is the magnitude of the gravitational force between
the two point masses,
G is the gravitational constant,
m1 is the mass of the first point mass,
m2 is the mass of the second point mass, and
r is the distance between the two point masses.
