Navigational Aid
Orion is very useful as an aid to locating other stars. By extending the line of the Belt southeastward, Sirius (α CMa) can be found; northwestward, Aldebaran (α Tau). A line eastward across the two shoulders indicates the direction of Procyon (α CMi). A line from Rigel through Betelgeuse points to Castor and Pollux (α Gem and β Gem). Additionally, Rigel is part of the Winter Circle. Sirius and Procyon, which may be located from Orion by following imaginary lines (see map), also are points in both the Winter Triangle and the Circle.

Famous quotes containing the word aid:
“A man, said Oliver Cromwell, never rises so high as when he knows not whither he is going. Dreams and drunkenness, the use of opium and alcohol are the semblance and counterfeit of this oracular genius, and hence their dangerous attraction for men. For the like reason they ask the aid of wild passions, as in gaming and war, to ape in some manner these flames and generosities of the heart.”
—Ralph Waldo Emerson (18031882)
