Rasalas

Rasalas is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Arabic. It is the name of HIP 48455 (μ Leo, HR 3905) in constellation Leo.

Etymology and History

Applied in recent times from an abbreviation of its sci-A name ra's alasad (al-shamali), "(the Northern [Part] of) the Lion's Head". As originally applied, μ Leo was "Rasalasad Borealis" (abbreviated in the first Western astronomical source as "Rasalas. Bor." for lack of space in the line), and ε Leo was "Rasalasad Australis" (after the sci-A).
