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.

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 Tupac Shakur'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.
| Thick line, Mercury to Venus | SQUARE 0.33° |
| Thin line, Sun to Sun | SEXTILE 1.75° |
| House ring, not drawn | |
Why they click
Sun sextile Sun at 1.75 degrees is the one easy contact and the reason identity scores mid-scale. A sextile between Suns is a workable angle: two people who recognise something of themselves in the other without needing to be alike. With only four aspects on the board, this pairing has a narrow area of genuine contact, and that Sun sextile is most of it.
Why they clash
Friction is by far the highest category, and both drivers are hard. Mars square Mars describes two people whose pace and appetite pull crossways, and Sun opposite Mars puts one chart's drive directly against the other's identity. Mercury square Venus at 0.33 degrees is the tightest aspect here and sharpens the exchange further. Communication, attraction and values all sit at the floor. This is a chart with contest in it and little cushioning.
What each system says
Twelve systems, two people

Frequently asked
Are Madonna and Tupac Shakur astrologically compatible?
Their charts make 4 cross-aspects, the tightest at 0.33° and 1.75°. 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 Madonna and Tupac Shakur 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 square mean between two charts?
A square puts two placements at a right angle, generating friction that tends to force action. Madonna and Tupac Shakur have 2 square contacts between them, more than any other type.
