Raj Koothrappali: zodiac sign and birth chart
Raj Koothrappali is a Libra, born on October 6. The show never gives a year, so his Moon and the rest of his chart come from NEBO's take. Libra fits the guy who loves company, romance and a good rom-com, and who goes silent around the one person he wants to impress.

SourceBirthday: Season 4, "The Prestidigitation Approximation," where Raj answers "October sixth." The show never gives a year, so only the Sun is canon. The other planets are NEBO's take.

NEBO's take
Canon says Libra. Our model says Scorpio.
We ran Raj 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 Scorpio first, with a Cancer Moon and rising and Pisces Mars: water almost everywhere.

CanonLibraNEBO's takeScorpio
Canon's Libra is the romantic who wants a partner. Scorpio is the intensity underneath, which he can't say out loud: in the Pilot he can't speak to Penny at all.
- Moon
CanonNo birth yearNEBO's takeCancer
Cancer Moon is soft with the people it loves, dog included. Howard even invents a game where friends guess whether an embarrassing quote was said to his girlfriend or his dog.
- Rising
CanonNo birth timeNEBO's takeCancer
No birth time in canon. First impression, Cancer style: shy and sweet. He can't talk to Penny, but she vents to him in the hallway and ends up hugging him.
- Mercury CanonNo birth yearNEBO's takeNo clear pick
- Venus
CanonNo birth yearNEBO's takeScorpio
Scorpio Venus loves intensely. Penny sets him up with her friend Emily, for whom his silence around women is not a problem.
- Mars
CanonNo birth yearNEBO's takePisces
Pisces Mars goes around obstacles rather than through them. While Leonard is away on the North Sea expedition, Raj learns to talk to women without a drink.
Where we agree: both are signs of relationships. Libra wants a partner and a bit of charm, Scorpio wants it deep, and Raj's chart is a lot about wanting love more than anything.

Talks to the dog like a person
Howard invents the game "Emily or Cinnamon," where the gang guesses whether one of Raj's embarrassing quotes was said to his girlfriend or his dog. Raj is annoyed, but the quotes say a lot about how soft he is.
