Might not be perfect but atleast it is clear and cant be totally misunderstood.
Has a star is perfectly fine. Now if it said has one star, I would tend to agree (though technically still true, it is not what it implies and would be like : "which month has 28 days. All of them" which is technically true, but not what is implied and just people trying to be a smartass imo)
