Sun trine or sextile Mercury

Mercury orbits inside the Earth's path and never appears more than twenty eight degrees from the Sun, so a trine or sextile between them cannot occur in any chart. The pairing is listed here for completeness and to explain the absence. Readers looking for an easy Sun and Mercury signature are usually looking at the conjunction, or at Mercury in the sign before or after the Sun's, which is as far as the two ever separate. Any chart software reporting this aspect has a calculation error, most often a wrong ephemeris or a body mislabeled.
