Asterina itsas izar txikien generoa da, Asterinidae familiakoa. Barnean hogeita hamar espezie baino gehiago ditu.
Bost mutur dituen ekinodermoa da. Txikia da eta oso beso laburrak ditu, zabalak oinean. Horrek ematen dio bost muturreko izar itxura. A. gibbosa, Mediterraneo itsasoan eta Atlantikoan bizi dena, eta A. pancerii, Mediterraneokoa, dira Europan ikusten diren mota ezagunenak.[2]
