Sheldon Cooper: zodiac sign and birth chart
Sheldon Cooper has no canon birthday. The show never settles on one, so his chart is NEBO's take, read from personality. That makes him an Aquarius: Sun, rising, Venus and Mars all in the sign of the lovable weirdo with rules nobody else agreed to. A Taurus Moon explains the couch spot, and nothing can explain the talking.

NEBO's take
No birthday in canon. His personality says Aquarius.
We ran Sheldon through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as air first: a head full of rules, with a stubborn Taurus Moon underneath.

CanonNot in canonNEBO's takeAquarius
Aquarius writes its own rules for everything, even friendship. He draws a flowchart for making friends and takes it all the way to a climbing wall.
- Moon

A Taurus Moon wants comfort and sameness. When Sheldon is sick, the only thing that helps is Soft Kitty, and Penny is the one who sings it.
- Rising
CanonNo birth timeNEBO's takeAquarius
No birth time in canon. First impression: well-meaning and a little alien. He sneaks into Penny's apartment at night to organize it and can't see why she's furious.

CanonNot in canonNEBO's takeAquarius
Aquarius loves in its own way. Penny gives him a napkin used and signed by Leonard Nimoy, and Sheldon answers with every gift basket he bought and a rare hug.
- Mars
CanonNot in canonNEBO's takeAquarius
Aquarius Mars digs in on principle. Told to learn to drive, he decides he's too highly evolved for it and moves into his university office instead.
What canon does give: a genius who runs on schedules, rules and one exact spot on the couch. Aquarius answers it with a world built to his own logic, and the Taurus Moon answers it with comfort.
How he shows up
Why he's like this
Aquarius is the sign of the outsider, the original thinker and the person who plays by their own rules. Sheldon hits every one of them, in scenes fans know by heart.
CoreAquarius Sun
Friendship by flowchart
Told that making friends is a skill, he finds a children's book, builds a flowchart and tests it on Kripke. It ends on a climbing wall, where he faints from fear of heights.
Season 2, "The Friendship Algorithm"
FeelingsTaurus Moon
Comfort has a song
Sick and terrified of germs, he gets Penny at his side singing Soft Kitty, the lullaby his mother used to sing. It works.
Season 1, "The Pancake Batter Anomaly"
First impressionAquarius rising
Helpful in the strangest way
Penny's apartment is a mess, so Sheldon can't sleep. He sneaks in at night to organize it, drags Leonard along, and Penny is furious in the morning.
Season 1, "The Big Bran Hypothesis"
LoveVenus in Aquarius
Love by exact value
He panics about matching Penny's Christmas gift, so he buys the whole range of bath items. Her gift is a napkin Leonard Nimoy used and signed, and Sheldon hands over every basket and a rare hug.
Season 2, "The Bath Item Gift Hypothesis"
In a fightMars in Aquarius
Too evolved to drive
With Leonard busy at night, Sheldon begs rides and gets thrown out of every car for being annoying. Told to learn to drive, he turns out to be terrible, declares himself too highly evolved for it, and moves into his office.
Season 2, "The Euclid Alternative"
