  • The most favourable conditions for a total eclipse are when the Moon is at its perigee, Earth is farthest from the Sun (around July) and when the Sun is observed near zenith.
  • Whereas the synodic period is 29.53 days, it takes 27.5 days for the moon to move in its elliptical orbit from perigee to perigee.

Origen

late 16th century: from French périgée, via modern Latin from Greek perigeion 'close round the earth', from peri- 'around' + 'earth'.
