Sun and Mercury Sign Traits: An Analysis

Mercury never strays more than 28° from the Sun, so it’s usually in the same sign as the Sun or the one next to it. When Mercury shares the Sun’s sign, people tend to communicate in ways that closely align with their core intentions. If Mercury is in the sign before the Sun, expression may feel blocked or more guarded, with a greater pull toward daydreaming. When Mercury is in the sign after the Sun, people often take a more objective, practical view and make good use of that sign’s strengths and resources.
