Uranus is the oddball of the solar system. For starters, it rolls along its side -- on its equator -- instead of spinning upright in its orbit the way planets typically do. Uranus is also in retrograde for more than half of the year. This means it is only direct for two weeks, and is retrograde for about five months out of every Earth year.
 

Astrologically, Uranus liberates you from the shackles of convention and applies pressure to change whatever is stagnant in your life. Uranus rules electromagnetic energy and is like a lightning storm that creates chaos as it cleans the air, revealing a fresh new world once the storm has cleared.
 

But when Uranus is retrograde, expect the unexpected. Wonderful and startling surprises are very possible. This retrograde may set your wild side free, or it could make a notoriously outgoing person uncharacteristically shy.
 

To know exactly what to expect, review the placement of Uranus in your birth chart. If Uranus is direct in a chart, intuitive and inventive impulses flow on a regular basis. However, when Uranus is retrograde in a birth chart, rebellious urges tend to bottle up and then burst forth, seemingly out of nowhere. A retrograde period seems to reawaken freedom urges within individuals, causing them to suddenly and unconsciously rebel against any ruts or confinement in life. Is Uranus retrograde in your birth chart? Should you be on guard against your own rebellious tendencies in the following months to come?
