Planetary retrogrades occur when a planet appears to move backward in its orbit from our perspective on Earth. This optical illusion happens due to the relative positions and speeds of the planets in the solar system. While all planets can experience retrograde motion, it is most commonly associated with Mercury, Venus, and Mars. During a retrograde period, the energies associated with the planet may feel intensified or disrupted. For example, Mercury retrograde is often linked to communication issues and technological glitches. These periods are seen as opportunities for reflection, reassessment, and resolving past matters.
