De acordo com o wiki ,
Hosnian Prime is the Capital of the New Republic, and the whole Hosnian System is what we see destroyed in the movie. Their was "chatter on D'Qar when they're planning the Starkiller raid that it was the 'Hosnian System' that was destroyed."
Isto é baseado em ambas as referências no filme, bem como em um novo livro A Força Desperta o Ditador Visual
