The AA rating means the time comes from a birth certificate or birth record, so the rising sign, the Midheaven and the houses below can be taken at face value. Open Serena Williams's chart on Astrolas alongside this read.
One feature runs the whole chart. Six of the ten planets sit in the 6th house, the part of the chart the Astrolas library ties to daily work, routine and the habits that hold a life together. Five of those six also share one sign, jLibra.
Williams turned professional in 1995 and went on to win 23 Grand Slam singles titles, the most of the Open Era, plus four Olympic gold medals, several of them in doubles with her sister Venus. The chart does not explain the talent. It lines up with where the hours went: the same drills, the same conditioning blocks, the same routine held for more than two decades.
Five planets in Libra, six in the 6th house
In order of degree: Saturn at 11ยฐ43', Sun at 3ยฐ49', Jupiter at 17ยฐ03', Pluto at 23ยฐ27' and Mercury at 29ยฐ39', all Libra, all in the 6th house. The Moon joins the group in the same house, from Virgo, which the next section covers on its own.
The library's Libra texts describe the drive behind the work. Sun in Libra is guided by Venus, carrying charm and a fair-minded streak, with the caution that too much weighing of options can tip into hesitation. Mercury in Libra weighs every side before deciding and works best alongside a decisive partner. USaturn in Libra is read as a favorable placement here: clear judgment, tact and a strong belief in fairness that suits a mediator. Jupiter in Libra brings luck through partnership, cooperation and diplomacy. Pluto in Libra is a generational marker from the 1970s and early 1980s tied to the push for equality; on a personal level it brings a drive for cooperation built on mutual fairness.
The 6th-house texts read like a job description for a professional athlete. Sun in the 6th ties self-worth to the work itself, with high standards and a risk of working past the point of rest. Saturn in the 6th puts duty ahead of leisure and takes on tasks nobody assigned. Jupiter in the 6th says opportunities arrive easily through work, with the lesson being to expand authority step by step into a role that fits. PPluto in the 6th brings a passion for finding leaner, more efficient ways to do the job, usually handled personally rather than delegated.
Three conjunctions inside the group
Three aspects connect planets within that Libra group, all fairly wide but all carrying library text. Jupiter conjunct Saturn, orb 5ยฐ20', is read as idealism running into obstacles, with persistence as the way through and results that arrive slowly but last. Mercury conjunct Pluto, orb 6ยฐ12', describes a strategic, fierce mind built for staying ahead of rivals, suited to research or investigation. Jupiter conjunct Pluto, orb 6ยฐ25', brings a clear vision and the chance for major turning points, tied to will and a transformation into a stronger version of oneself.
Late in her career, Williams lost four Grand Slam finals in a row chasing a 24th major, a long stretch of near misses that fits the obstacles the library ties to Jupiter and Saturn. Her game was built on reading an opponent and finding the gap, which fits the Mercury-Pluto pairing. When she stepped away from professional tennis in 2022, she wrote about the decision as an evolution rather than a retirement, turning her attention more fully to the venture capital firm Serena Ventures, which she had already founded years earlier. That framing lines up with Jupiter conjunct Pluto better than an ordinary account of stepping back would.
Moon in Virgo, the sixth planet in the 6th house
The Moon sits at 20ยฐ24' hVirgo, also in the 6th house, completing the group of six. The library's Virgo Moon is practical and reserved with feelings, slow to trust, and most at ease when everything is orderly and under control. Its 6th-house placement ties emotional steadiness directly to daily routine and feeling useful, with a tendency toward anxiety when that order breaks down.
That is a fitting emotional engine behind the discipline described above: a need for control translated into thousands of repeated hours, with satisfaction coming from the work itself rather than from any single result.
Venus and Uranus together in Scorpio, in the 7th house
Venus sits at 16ยฐ20' and Uranus at 27ยฐ15', both kScorpio, both in the 7th house of partnership. The library's Scorpio Venus loves with total intensity and can tip into possessiveness, while Scorpio Uranus brings sudden shifts in money or circumstance and a magnetism that is hard to predict. Uranus in Scorpio is generational, shared by Williams's whole birth cohort; what makes it personal here is the house it falls in, the 7th, right alongside Venus. The 7th-house reading of Venus points to charm paired with caution, built for a slower, more deliberate approach to trust rather than rushing in.
Venus also squares Mars, orb 0ยฐ45', one of the tightest aspects anywhere in the chart, though the library has no text for that pairing yet. Williams married Alexis Ohanian in 2017, and the couple has spoken about building a family and separate ventures side by side, a public version of a 7th house carrying both intensity and independence.
Mars in Leo, in the 5th house
Mars sits at 15ยฐ35' gLeo, in the 5th house of competition, creativity and children. The library's Leo Mars refuses to accept average and wants to leave a personal signature, with a gift for performing and for lifting a team, provided the drive to be the center does not overpower collaboration. The 5th-house reading adds a love of competitive sport specifically, along with a tendency to watch over children closely out of a wish to protect them.
Williams has a daughter, Olympia, born in 2017. The library's note about overseeing children out of worry and a desire to protect fits a parent who built a career on controlling every variable she could.
Neptune in Sagittarius, in the 8th house
Neptune sits at 22ยฐ14' Sagittarius, in the 8th house, the part of the chart tied to shared resources and other people's money. This is a generational sign placement, read by the library as a pull toward meaning, education and a global perspective. Its 8th-house placement adds strong intuition and a knack for ventures that depend on creative instinct, with a caution to stay transparent in shared finances.
That intuitive read on investment lines up with her move into venture capital, backing founders that traditional venture firms often pass over.
Taurus rising, and the aspects still waiting on text
The Ascendant sits at 3ยฐ10' sTaurus, with the Descendant at 3ยฐ10' Scorpio, the Midheaven at 17ยฐ19' Capricorn and the IC at 17ยฐ19' Cancer. The Astrolas library does not yet have entries for any of the four angles on their own. Three of the tightest aspects in the whole chart touch them anyway: Jupiter square the Midheaven, orb 0ยฐ16', Venus sextile the Midheaven, orb 0ยฐ59', and Mercury opposite the Ascendant, orb 3ยฐ31'. Without library text for any of the three, this article treats them only as structure, not meaning.
What the chart adds up to
The chart does not explain how someone becomes one of the most dominant athletes in the history of a sport. What it shows is where the effort was aimed: six planets out of ten sitting in the house of daily work, five of them sharing a sign built around fairness and partnership, with a Virgo Moon underneath demanding order before it can rest.
