For eclipses (any of partial, total, annular, or penumbral) to occur, the nodes do nothave to be exactly on the Earth-Sun line: i.e., the line drawn through the centersof Earth and Sun. This is because the light-emitting body, the eclipsing body, andthe eclipsed body all have finite size. The eclipse season is the period during whichnodes are sufficiently close to an exact nodal alignment that an eclipse is possible.The eclipse season for the Sun (total, annular, and partial) is about 34 days: 17 daysbefore exact alignment and 17 days after. Will there be solar eclipse of some kind inevery solar eclipse season?
