Bootes may be a hunter, on the tracks of the Great Bear, accompanied by his two dogs Asterion and Chara (the constellation "Canes Venatici").The constellation was once known as Arctophylax which means the protector of the Bear. Yet the name itself, Boötes, comes from the Greek, as first mentioned in Homer, and means 'ox-driver'. The Romans called him Venator Ursae: the Bear Hunter. Nowadays Boötes is sometimes considered to be a Herdsman (as in French: Le Bouvier), as he eternally shepherds the stars around the North Pole. As mentioned above, the first recorded appearance of Boötis is found in Homer's Odyssey. In Book V Odysseus sails his ship by the stars, using the Pleiades, the Bear, and Boötes. The star called Arcturus means "Guardian of the Bear". This orange-red giant is about 20-25 times the size of the Sun, with about the same mass. In fact the Sun will probably take the same path, eventually ballooning to the same size in another five billion years. NGC 5248 is a spiral galaxy that is part of the Virgo Cluster: however on a star chart the galaxy is found to be within constellation boundaries of Bootes.
Spiral galaxies have arms, can you see how many arms NGC 5248 has?
