    The house(s) will reveal which activities and parts of your life experience your Cancer-infused planets will work through. What areas of your life will your dominant cancer energy play out in the most?

Transiting Cancer Stellium

The positions of your natal planets aren’t the only way you can experience a stellium in the sign of Cancer. You also have the potential to have a planetary supergroup in the sign of the crab through the transiting planets.

In astrology, the currently moving planets are described as transiting. Transiting planets connect and collaborate with the placements, signs, and houses in your own chart and can introduce change and transition into your life.

With a transiting stellium interacting with your sign of Cancer, this could have the same type of influence as it could if it were made from your natal planets, but with one huge difference. The significance of a transiting stellium is temporary

A transiting stellium in Cancer may be capable of ushering in important changes in your life, but its power will dissipate as the group of planets break apart and move on.
