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:
“There aren’t any good, brave causes left. If the big bang does come, and we all get killed off, it won’t be in aid of the old-fashioned grand design. It’ll just be for the Brave New-nothing-very-much-thank-you. About as pointless and inglorious as stepping in front of a bus. No, there’s nothing left for it, me boy, but to let yourself be butchered by the women.”
—John Osborne (1929–1994)
