Simon Helberg’s zodiac sign and chart, in brief
Simon Helberg was born in Los Angeles, California, on 9 December 1980, a Tuesday. That makes Simon a Sagittarius, with the Moon in Capricorn. Simon turns 46 in 2026. StarMap has no verified birth time for Simon, so the chart is cast for midday and leaves the houses out.
Of the ten planets, three are in fire signs, three in air, two in earth and two in water. Cardinal signs hold five, mutable signs three and fixed signs two. Sagittarius holds a stellium, three planets in one sign: Sun, Mercury and Neptune. Jupiter, Saturn and Pluto all fall in Libra. They are slow planets, so the grouping is shared with people born around the same time. No two planets sit closer to an exact angle than Mercury and Jupiter: a sextile, about 1.1° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. No planet was retrograde. The Moon was a waxing crescent.
StarMap's dataset holds 17 other people born on 9 December, among them Kirk Douglas, Judi Dench and John Malkovich.

Simon Helberg’s Sun, Moon and rising sign
Sun sign
Sagittarius
about 17° Sagittarius at midday
A Sagittarius Sun seeks. Meaning, distance and the bigger picture are likely to pull Simon Helberg forward, and the honesty of this placement is a kind of generosity. Its lesson is that the journey also needs somewhere to land.
Moon sign
Capricorn
in this sign all day; the degree depends on the birth time
A Capricorn Moon feels responsibly. With it, Simon may hold themselves together for other people, and can be hard on themselves when they cannot. This Moon tends to be restored by accomplishment, by structure, and by the rare person allowed to see them tired.
Rising sign
The rising sign changes about every two hours, so it cannot be known without a birth time. The table below shows which sign was rising over Los Angeles, California, at each hour of the day.
Simon Helberg’s rising sign, by birth time
StarMap has not verified a birth time for Simon yet. It shows a birth time only when Astro-Databank rates it AA, A or B on the Rodden scale (AA from a birth certificate or record, A from the person, someone close to them or a news report, B from a biography). Until then, this is the rising sign for every possible time of birth on 9 December 1980, computed for Los Angeles, California.

Simon Helberg’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Simon Helberg’s private life.
Growth, travel and ideas bigger than daily life are where Simon Helberg's Sagittarius Sun finds purpose, and their energy tends to lift the moment there is somewhere new to go. Familiarity is what wears on this placement. A few months into any routine, however good it is, restlessness usually sets in.
With the Moon in Capricorn, Simon's comfort probably comes from accomplishing something concrete each day, and an unproductive day can leave them oddly unsettled even on holiday. Harder feelings tend to be kept for when they are alone. Before rest is allowed there is usually one more thing to tidy, organise or finish.
Simon's Mercury in Sagittarius thinks in big, connective leaps and communicates with enthusiasm and a wide frame of reference drawn from everywhere they have been. The weak point is generalising past what the details support. A specific question may get a sweeping theory nobody quite asked for.
Venus in Scorpio loves intensely and privately, and Simon is likely to value depth and total honesty over ease. Testing loyalty can create the very distance this placement fears most. There is an all-or-nothing quality to how this Venus commits, with little interest in anything in between.
Mars in Capricorn acts with discipline and patience, playing a longer game than most, and in Simon's case its anger tends to be controlled, arriving as coldness rather than heat. The tendency is to go quiet and distant instead of saying what is wrong. A frustration is something to outwork rather than voice.
Jupiter in Libra
7° Libra 15' at midday
growth and excess
In Simon's chart, Jupiter in Libra suggests growth through partnership and a gift for bringing people together. Excess here looks like pleasing people so broadly that every expectation becomes a commitment. Someone with this Jupiter is often the connector whose introductions and events other people benefit from more than they realise.
For Simon, Saturn in Libra means discipline built around relationships, and fairness and commitment are trusted slowly. The doubt is overthinking whether a partnership is truly equal. With time, people with this Saturn tend to become the ones others rely on to negotiate and to keep things fair.
Uranus in Scorpio
27° Scorpio 11' at midday
freedom, generational
Much of Simon's age group has Uranus in Scorpio. It changes attitudes to power, secrecy and what is held in common, often while living through upheavals in institutions once considered permanent. In an individual it tends to be a low tolerance for hidden agendas.
Neptune in Sagittarius
22° Sagittarius 13' at midday
imagination, generational
Neptune in Sagittarius is the dream of a generation: grand systems of belief and utopian journeys. What belongs to Simon in it may be a hopeful conviction that the right philosophy will resolve a practical problem.
Pluto in Libra
23° Libra 40' at midday
power, generational
Pluto in Libra is the signature of the generation Simon belongs to, because Pluto moves so slowly. That generation transforms ideas of partnership, fairness and what people owe one another. Personally it can be an intense need for relationships to be fundamentally fair.
Aspects in Simon Helberg’s chart
How the planets stand to each other, tightest first. Without a birth time the orbs are those at midday, and aspects to the Moon are left out because the Moon moves about thirteen degrees in a day.
Mercury sextile Jupiter
about 1.1° at midday
Simon Helberg's thinking and optimism keep easy company, which gives their conversation a natural, engaging breadth. Curiosity does much of the work with this aspect, opening doors in conversation that a narrower focus would have missed.
Jupiter conjunction Saturn
about 1.1° at midday
Growth and discipline are unusually well matched when Jupiter is conjunct Saturn, so Simon's optimism tends to come with a realistic plan attached. It is an effective combination for building things that last, with vision balanced by the patience to see it through.
Mercury sextile Saturn
about 2.3° at midday
Turning a loose idea into something solid is easier with Mercury sextile Saturn, because Simon's thinking and sense of structure work together. The clarity is quiet and practical, and it shows most when a plan has to work.
Sun conjunction Neptune
about 4.3° at midday
A Sun-Neptune conjunction tends to make Simon's sense of self porous and imaginative, drawn towards ideals, art or causes bigger than everyday life. Compassion and creativity come with it, and so does the task of keeping a clear enough sense of who they are underneath the dream.
Mars square Saturn
about 5.2° at midday
Simon's drive can meet resistance, from outside obstacles or from private doubt, and frustration builds when progress feels blocked. Under this square, every stretch of steady work done anyway turns that resistance into competence, the kind that is there when it is needed most.
Mars square Jupiter
about 6.3° at midday
Drive can outrun capacity under Mars square Jupiter, and Simon may overextend on a project or on a promise made in a burst of confidence. The enthusiasm is sound. It needs matching to a pace that can be sustained.
One more aspect, listed without a reading. It is between two of Uranus, Neptune and Pluto, whose aspects hold for years at a time, so everyone born while it holds shares it.

How this page is made
Planet positions are computed with the astronomy-engine ephemeris and checked against Swiss Ephemeris. Birth dates and places come from Wikidata; birth times, where StarMap has one, come from Astro-Databank and are shown with their Rodden rating. The readings describe what a placement is traditionally taken to mean. They are written by StarMap for reflection and entertainment, not as statements about the person’s private life. New to charts?
