This page compares Sun, Mercury, Venus and Mars, the four placements a birth date alone can place. Moon, Ascendant and Midheaven are left out here by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.

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.
Guna Milan: 25 of 36
A second tradition
Guna Milan (Ashtakoot)
Guna Milan is the compatibility method used in Vedic matchmaking, traditionally consulted before an arranged marriage. It scores eight factors between two Moon placements on a 36-point scale, shown here as what this one tradition reads: not a verdict, and not averaged with the Western reading above, which may disagree.
25 of 36 points
Two things stated plainly rather than left silent: Varna and Vashya use a directional rule from traditional bride/groom roles, applied here in the order the two people are listed on this page rather than assigning either role. Bhakoot dosha's most common cancellation, matching rashi lords, is applied; Nadi dosha carries no cancellation here, though same-nakshatra-different-pada is sometimes cited elsewhere as easing it. Mangal (Kuja) dosha is a separate check and isn't part of this reading.
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.
