Values
VENUS × VENUS
No aspect inside orb. Their values neither align nor clash by this measure.
None
Scores rank how close a contact is to exact, not how well two people get along. A high friction score means the two Mars are in tight aspect, which is information, not a warning.
The overlap
Two charts, laid over each other
Madonna and Dennis Rodman's Sun, Mercury, Venus, Mars and Moon are drawn here, along with the house ring and ascendant axis both charts support. This is a complete chart of what is known, not a partial chart of what is not.

Why they click
This is the strongest overall reading in the corpus, and the precision is the reason. Mercury square Mercury sits at 0.13 degrees and Sun square Sun at 0.72, both close to exact. Venus conjunct Mars adds direct physical charge on top. Identity, communication and attraction all score in the eighties or higher, which is rare: most pairings light up one category, and this one lights three.
Why they clash
Both of the tight contacts are squares, so the intensity is the abrasive kind rather than the comfortable kind. Two Suns and two Mercuries at right angles describe people who engage constantly and settle nothing, drawn in without either giving ground. Friction and values both sit at the floor, so there is no shared sense of what matters underneath the charge. High voltage, no ballast.
What each system says
Twelve systems, two people
The Suns are 91° apart, close enough to feed the identity category above.
Dog and Ox are in neither the trines nor the clashes.
Frequently asked
Are Madonna and Dennis Rodman astrologically compatible?
Their charts make 4 cross-aspects, the tightest at 0.13° and 0.72°. Astrology does not score a relationship out of a hundred, and the number on this page counts how much contact two charts make, not how well two people do.
What does square mean between two charts?
A square puts two placements at a right angle, generating friction that tends to force action. Madonna and Dennis Rodman have 2 square contacts between them, more than any other type.
