Special Perturbations,his case, substantial changes are possible — as may be observed with various periodic comets. Examples are Comet P/Pons-Winnecke (1819 III), whose orbital inclination increased from 10° to 22° between 1819 and 1976 because its aphelion lay close to Jupiter, and Comet P/Wolf (1884 III), whose orbital

The Orbit of the Moon,tance of some 150 million km, superimposed upon which there are small monthly oscillations. Because the gravitational force is never directed away from the Sun, the orbit, despite these oscillations, is always concave towards the Sun.

Solar Eclipses, of the Moon’s orbit remained fixed in space, all eclipses would take place in two specific months. Because of the regression of the line of nodes of the lunar orbit, the dates of eclipses shift by an average of three weeks each year. The period of 18.6 years taken for one complete regression of the

It provides accurate conversions between ecliptic and equatorial coordinates, and between geocentric and heliocentric coordinates, for various epochs. The individual transformations

Furthermore, the orbit’s departure from the ecliptic can be described by a brief approximation, thus doing away with the complication of calculating Gaussian vectors. These approximations will be described in greater detail in the next se
