_Betelgeuse_ and _Rigel_ are in the constellation _Orion_, being about equally distant to the north and south from the three stars forming the _belt_ of Orion. Betelgeuse is a red star. _Sirius_ is the brightest star in the heavens, and belongs to the constellation _Canis Major_, or the _Great Dog_. It lies to the east of the belt of Orion. _Aldebaran_ lies at about the same distance to the west of the belt. It is a red star, and belongs to the constellation _Taurus_, or the _Bull_. _Capella_ is in the constellation _Auriga_, or the _Wagoner_. These stars are visible in the evening, from about December to April. 336. _Orion and his Dogs, and Taurus._--_Orion_ and his _Dogs_ are shown in Fig. 387, and _Orion_ and _Taurus_ in Fig. 388. _Aldebaran_ marks one of the eyes of the bull, and is often called the _Bull's Eye_. The irregular _V_ in the face of the bull is called the _Hyades_, and the cluster on the shoulder the _Pleiades_. [Illustration: Fig. 387.] [Illustration: Fig. 388.] [Illustration: Fig. 389.] 337. _The Wagoner._--The constellation _Auriga_, or the _Wagoner_ (sometimes called the _Charioteer_), is shown in Fig. 389. _Capella_ marks the _Goat_, which he is represented as carrying on his back, and the little right-angled triangle of stars near it the _Kids_. The five chief stars of this constellation form a large, irregular pentagon. Gamma of _Auriga_ is also Beta of _Taurus_, and marks one of the horns of the _Bull_. [Illustration: Fig. 390.] 338. _Pegasus, Andromeda, and Perseus._--A line drawn from Polaris near to Beta of _Cassiopeia_ will lead to a bright second-magnitude star at one corner of a large square (Fig. 390). Alpha belongs both to the _Square of Pegasus_ and to _Andromeda_. Beta and Gamma, which are connected with Alpha in the figure by a dotted line, also belong to Andromeda. _Algol_, which forms, with the last-named stars and with the _Square of Pegasus_, an asterism similar in configuration to the _Great Dipper_, belongs to _Perseus_. _Algenib_, which is reached by bending the line at Gamma in the opposite direction, is the principal star of _Perseus_. [Illustration: Fig. 391.] [Illustration: Fig. 392.] [Illustration: Fig. 393.] _Pegasus_ is shown in Fig. 391, and _Andromeda_ in Fig. 392. _Cetus_, the _Whale_, or the _Sea Monster_, shown in Fig. 393, belongs to the same mythological group of constellations.
