Template documentation[view] [edit] [history] [purge]

Usage

  • |tropical or |polar
  • |convert is optional.
{{Circle of latitude|Tropical|convert}} → 23°26′09.5″ (or 23.43598°)
{{Circle of latitude|polar}} → 66°33′50.5″

This template uses a continuously updating formula found at http://www.neoprogrammics.com/obliquity_of_the_ecliptic. Note that this formula calculates the Mean Ecliptic, not the True Ecliptic, because it doesn't correct for Nutation.
