Kinds of bright giant :

• Alpha Hydrae (11 facts) (HR 3748, Alphard)
• Alpha Lyncis (10 facts) (HR 3705)
• Alpha Reticuli (10 facts) (HR 1336)
• Alpha Sculptoris (10 facts) (HR 280)
• Alpha Trianguli Australis (10 facts) (HR 6217)
• Arcturus (13 facts) (Alpha Boötis, HR 5340) - A beautiful orange star that is the brightest in the constellation Bootes and the fourth brightest in the night sky. It lies 34 light-years away and is a member of the thick-disk population. Historically, Arcturus is famous because it was one of the first stars to have its proper motion measured., An old subgiant disk star (K2 IIIp, m_v = 0.06) about 11 pc distant.
• Beta Trianguli (10 facts) (HR 622)
• Mintaka (5 facts) - One of the three stars in Orion's belt, and the star along whose line of sight interstellar gas was first spectroscopically detected.
• Pollux (13 facts) (beta Gem, HR 2990) - A K0 III star.
