on Bereniken hiusten tähdistössä oleva, Aurinkoa muistuttava keltainen pääsarjan tähti.

Tähdellä havaitaan 16,6 vuoden auringonpilkkujakso spektriviivoissa sekä myös toissijainen 9,6 vuoden jakso. Tähti ei ole spektroskooppinen kaksoistähti,
eikä siltä ole havaittu eksoplaneettoja tai pölykiekkoa.
