Sterope (Στερόπη) is the Greek word for "lightning" or "flash." One of the seven Pleiades — daughters of Atlas and Pleione — who became the famous star cluster.
Used widely in modern Greece.
Sterope 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 Sterope reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
