Use the Stars to Find Your Way Home

What You Need:

A clear, starry night What To Do:
  1. Find the Big Dipper, part of the constellation Ursa Major, the great bear.
  2. Find the two stars that form the edge of the Dipper's bowl on the side away from the handle. These are your "pointer stars".
  3. Hold out your hand at arm's length. Notice the distance between the "pointer stars" is about the same as three finger widths. This distance is about 5°.
  4. From the "pointer stars" to Polaris is 28°, or slightly more than five times the distance between the "pointer stars". Now, holding your hand at arm's length, put your thumb at the lip of the Dipper's bowl and your baby finger out along the line of the two "pointer stars". Your baby finger should appear to be close to Polaris, the North Star, which forms the end of the handle of the Little Dipper, Ursa Minor (the little bear).
  5. Once you are looking at Polaris, the rest is easy: east is to your right, west is on your left, and south is behind you.
What Else You Can Do: Before your scurry home, you might want to take a short sky tour. In spring through early fall, following the curve of the Big Dipper's handle away from the bowl will lead you to orange Arcturus in the constellation Boötes, the herdsman. The top two stars in the bowl point at yellow Capella, in the charioteer, Auriga. Capella is best seen in late fall, winter and early spring. It is low along the northern horizon during the rest of the year.
