One shared axis
Muhammad Ali and Joe Frazier compatibility

Sources conflict on the birth time. No recorded verification, so houses and the rising sign are not shown.
Note on this rating: Birth time 07:00, Rodden DD (conflicting sources) via astrotheme.com. Treat angle-based placements with caution.
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.
Cross-aspects
Where the two charts actually touch
The overlap
Two charts, laid over each other
Muhammad Ali and Joe Frazier's Sun, Mercury, Venus and Mars are drawn here, the four placements a birth date alone can place with no birth time required. This is a complete chart of what is known, not a partial chart of what is not.
| Thin line, Mercury to Venus | SEXTILE 2.46° |
| Thick line, Sun to Sun | CONJUNCTION 6.17° |
| House ring, not drawn | |
Why they click
Sun conjunct Sun is the whole structure here. Wide at 6.17 degrees, but it puts both men in the same solar territory: the same appetite for the spotlight, the same read on what a public life is for. Ali's Mercury sextiles Frazier's Venus, one soft secondary link that makes the pair legible to each other outside the ring. Two aspects in total, which is about as thin as a reading gets.
Why they clash
Two charts, two aspects. There is no Mercury to Mercury contact, no Venus to Venus, no Mars to Mars, so four of the five categories sit at the no-contact baseline. The one thing they share is the Sun, and a conjunction between Suns is not agreement: it is occupancy of the same ground. Two people wanting the same position, with no verbal channel to negotiate it and no shared Venus to make room. The chart gives them one axis and no mechanism for splitting it.
What each system says
Twelve systems, two people
The Suns are 6.2° apart, close enough to feed the identity category above.
Snake and Goat are in neither the trines nor the clashes.
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.
Guna Milan needs an exact birth time for both people. The Moon changes nakshatra roughly once a day, so an estimated time can place the whole reading in the wrong one, and at least one birth time here isn't exact.

Editorial note · Saturn square Ascendant
Arriving 18 days after the bout, Saturn squaring the Ascendant from the tenth house marked a grueling power window of public reckoning and sobering career gravity.

Frequently asked
Are Muhammad Ali and Joe Frazier astrologically compatible?
Their charts make 2 cross-aspects, the tightest at 2.46° and 6.17°. 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.
Why isn't there a house ring on the chart above?
At least one of Muhammad Ali and Joe Frazier doesn't have a curated, non-estimated birth time, so a house placement would be a guess. This page only shows what a birth date alone can place.
What does conjunction mean between two charts?
A conjunction puts two placements at nearly the same degree, so their energies blend into one signal rather than two. Muhammad Ali and Joe Frazier have one conjunction between them.
Minimal contact
See what a wider lens finds
This page compares Sun, Mercury, Venus and Mars, because those are the four that a birth date alone can place. With this few cross-aspects between the two, a midpoint chart is often the more informative object.
