Personality Traits by Sun and Mercury Sign Combination

People with the same Sun sign can express themselves very differently depending on Mercury. Mercury always stays close to the Sun—its angular distance never exceeds 28°—so it often falls in the same or an adjacent zodiac sign as the Sun.

When the Sun and Mercury share a sign, people tend to express their thoughts and intentions with complete authenticity. If Mercury is in the sign before the Sun, expression may be hindered or more cautious, with a tendency toward daydreaming and fantasy. When Mercury is in the sign after the Sun, they usually take a more objective, practical view and can make effective use of that sign’s strengths and resources.
