Spica o Espiga (Alfa Virginis / α Vir / 67 Vir)^[9] ye la estrella más brillosa de la constelación de Virgu y la decimoquinta más brillosa del cielu nocherniegu. De magnitú aparente +1,04, alcuéntrase a 260 años lluz del Sistema Solar. Piénsase que Hiparco de Nicea afayó la precesión de los equinoccios a partir de los datos llograos d'Espiga.
