Thalia Grace: zodiac sign and birth chart
Thalia Grace is a Capricorn, born on December 22. Canon never gives the year, so the rest of her chart is NEBO's take. Capricorn fits the punk daughter of Zeus: black clothes, a short temper, sworn to serve. And the Zeus kid who is scared of heights.

Birth chart
Thalia's chart at a glance
Sun from the canon birthday. Canon gives no year, so the rest is NEBO's take from her character.
NEBO's take
Canon and our model agree. Capricorn.
We ran Thalia through the same model that matches people to characters in the app, and looked at which chart gets her most often. It lands on Capricorn too, with an Aries Moon and rising to explain the temper.

CanonCapricornNEBO's takeCapricorn
Canon and our model both land on Capricorn. She is serious, hard-working and quick to take responsibility, and underneath it, very tired.
- Moon
CanonNo birth yearNEBO's takeAries
No birth year in canon, so the Moon is our take. Aries reacts fast and says it loud. She calls Percy Kelp Head when she sees him again.
- Rising
CanonNo birth timeNEBO's takeAries
No birth time in canon. First impression, Aries style: spiky black hair, punk clothes, electric blue eyes and a look that dares you to say anything.
- Mercury
CanonNo birth yearNEBO's takeCapricorn
Capricorn Mercury is dry and practical. Her one weakness is the thing a daughter of the sky isn't supposed to have: she is terrified of heights.
- Venus
CanonNo birth yearNEBO's takeScorpio
Scorpio loves all or nothing. Thalia joins the Hunters of Artemis, a group that swears off romance, and takes the oath completely.
- Mars
CanonNo birth yearNEBO's takeCancer
Cancer Mars fights to protect. In The Titan's Curse she throws herself between the others and the monsters before anyone asks.
Where we agree: the Sun. Capricorn is duty, discipline and carrying more than your share, and Thalia has done that since she was a kid defending a hill. Our Aries is the part that bites back.
How she shows up
Why she's like this
Capricorn is the sign of duty, discipline and carrying the weight. Thalia hits every one of them, in scenes fans know by heart.
CoreCapricorn Sun
Holds the line for everyone else
As a kid she holds off monsters at the top of Half-Blood Hill so Luke, Annabeth and Grover can reach camp. The pine tree on the hill is what she became.

CoreCapricorn Sun
Duty over comfort
She comes back as a lieutenant of Artemis's Hunters and goes on the quest to find the missing goddess, with no complaints about the mission.
The Titan's Curse
FeelingsAries Moon
Quick with a nickname
She greets Percy by calling him Kelp Head. Any hope of a formal reunion lasts about as long as one insult.
The Titan's Curse
First impressionAries rising
Punk first impression
Spiky black hair, black clothes and electric blue eyes. Nobody mistakes her for a polite camper.
The Titan's Curse
MindMercury in Capricorn
Hates what she can't control
A daughter of the sky god is afraid of heights, and she hates that it's true, so she hides it with a joke.
The Titan's Curse
LoveVenus in Scorpio
All in or nothing
She takes the Hunters' oath, which means giving up romance for good. Thalia doesn't do things by halves.
