Mary Cooper: zodiac sign and birth chart
Mary Cooper has no canon birthday. The show never states one, so her chart is NEBO's take, read from personality. She's a Cancer: Sun and Mercury in the sign of mothers who hold the family together and say it plainly. A Pisces Moon is why she forgives Sheldon.

NEBO's take
No birthday in canon. Her personality says Cancer.
We ran Mary through the same model that matches people to characters in the app, and looked at which chart gets her most often. It reads her as water first: protective, forgiving and very Texan about it.

No birth time in canon. First impression, Capricorn rising: composed and dignified. The guys expect a monster and get a sweet, down-to-earth, devout woman.
- Mercury

Cancer Mercury says what she feels in plain words. At Christmas she tells Sheldon she never thought he'd find a partner, and it hurts him.

Leo Venus charms. She flirts with Dr. Gablehauser, and Sheldon gets his job back.
- Mars

Aquarius Mars stands on principle. She argues with Beverly after Beverly calls her beliefs a superstition.
What canon does give: a devout Texan mother who is nothing like her son's friends expect, and the only person who can make Sheldon apologize. Cancer answers it with a family-first protectiveness and plain speaking.
