Soraya (ثریا / ثرية) is the Persian and Arabic name for the Pleiades — the small star cluster known to Western astronomy as the Seven Sisters. The name has been a feminine given name in Persian-speaking countries for at least a thousand years, often given to daughters with a wish for them to shine.
Soraya Esfandiary-Bakhtiari was the second wife of Mohammad Reza Pahlavi, the last Shah of Iran. The name has carried that mix of glamour and melancholy ever since.
Soraya does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Soraya reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
