Legenda della tabella · Nome = nome proprio della stella. · B = designazione di Bayer nell'ambito della costellazione. · F = designazione di Flamsteed ove presente. · HD = numero della stella nel Catalogo Henry Draper. · HIP = numero della stella nel Catalogo Hipparcos. · AR = ascensione retta della stella all'Epoca dell'equinozio J2000.0. · Dec = Declinazione della stella all'Epoca dell'equinozio J2000.0. · vis. = magnitudine visuale della stella (m o m_v), conosciuta anche come magnitudine apparente. · ass. = magnitudine assoluta della stella (M_v). · Dist. (al) = distanza in anni luce dalla Terra. · Classe spettrale = classificazione stellare in base alla temperatura superficiale. · Note = principalmente sono indicati i nomi comuni con cui è conosciuta la stella; inoltre sono brevemente citate alcune peculiarità della stella (se è una stella doppia o multipla; se è una stella variabile, il tipo e il periodo di variabilità; se possiede esopianeti; ecc.).
