The Moon

Lunar libration and lunar limb profiles

PreviousFive Millennium Canon of Solar EclipsesNextLunar Libration

Last updated 11 months ago

You can calculate the position of the Moon in a variety of common coordinate systems using the end point and its rise, transit, and setting time using the end point.

Additionally, the Body Position end point can optionally return other Moon specific information, such as the illuminated fraction of the Moon's disc, waxing/waning state, and geocentric distance.

There are however some more specialized end points available which relate solely to the Moon: libration and the lunar limb profile. API end points are available to calculate both geocentric and topocentric lunar libration. For use specifically with solar eclipse calculations, a limited set of lunar limb profile data is available.
