The overlap
Two charts, laid over each other
Britney Spears and Kevin Federline'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.
| Thick line, Venus to Mars | OPPOSITION 0.66° |
| Thin line, Mars to Mars | SEXTILE 1.17° |

Why they click
Venus opposite Mars at 0.66 degrees is the engine of this chart and the reason attraction is the highest-scoring category by a wide margin. Venus and Mars in hard aspect is the classic signature of physical charge, and an opposition that tight is about as direct as the contact gets. Mars sextile Mars at 1.17 adds compatible pace alongside it. Sun trine Venus and Mercury trine Sun round it out with genuine warmth.
Why they clash
Identity, communication and values all sit at the floor of the scale. That is the whole story: an unusually strong attraction signal with nothing underneath it registering. Mars also opposes the other Sun at nearly eight degrees, and Venus squares Mercury, so what tension exists collects around drive and speech. A chart weighted this heavily toward one category describes a pull that is specific rather than general.
What each system says
Twelve systems, two people
The Suns are 111.1° apart, outside orb of any aspect, which is why identity reads as an empty channel above.
Rooster and Horse are in neither the trines nor the clashes.
Guna Milan: 4.5 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.
4.5 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.
