Duke Leto: zodiac sign and birth chart
Leto has no canon birthday. Frank Herbert's novels give only ages and years, never a day. Read from his personality, he's a Cancer, and every placement agrees: Sun, Moon, rising, Mercury, Venus and Mars. The Duke rules by loyalty and protects his people like family.

Cancer loves with devotion. He loves Jessica, though they never marry.
- Mars

Cancer fights to protect. He tries to reach the Baron even from captivity.
What canon does give: a duke who sees the trap and walks into it with his head up. A Cancer answer is to put the people first and trust that care for them is the power that lasts.
