Three Constellations You Should Know

Being able to determine direction can be critical to finding your way out of a “lost” scenario. The lights of the night can be helpful in your orientation by finding the North Star (or Polaris). As I reside in the Northern Hemisphere, I have come to rely on three constellations to aid me in finding Polaris, they are: the Big Dipper (Ursa Major); Cassiopeia; and Orion. There are certain stars within each constellation that “point” to Polaris.

The Big Dipper and Little Dipper are both shaped like ladles or dipping spoons and are large and small respectively. The Small Dipper (Ursa Minor) actually contains Polaris at the tail of it’s handle, but that constellation is quite dim and in some circumstances is barely visible. The Big Dipper however is brighter and much easier to locate visually. The outer two stars in the “cup” portion of the Big Dipper point upward to Polaris.

When viewing Cassiopeia as the letter “W”, I align an imaginary line from the first star on the left and the fourth star towards the right. Then from the fourth star I imagine a 90 degree line pointing straight upward that reaches Polaris.

When viewing the square outline of Orion, I visually connect the lower two stars to the upper right star. This imaginary triangle points upward to Polaris but you may find that you have to bend backwards a bit to make the connection.

During this late time of year these constellations are positioned for easy viewing overhead. Because of the Earth’s rotation the constellations may be rising or falling from East to West, and because of the Earth’s revolution, they may be high or low on the latitude of the Earth’s axis. Cooler weather often makes clearer skies at night so it is an excellent time to step outdoors and familiarize yourself with these constellations and how they relate to the North Star.

Consider thinking “South” for direction

I was having coffee outside on a deck today and decided that I wanted to know what direction I was facing. I looked at my wrist watch to notice the time relative to Noon and it gave me a ballpark bearing on South, because the sun is always due South at Noon (actually, Noon – “Standard Time”). You can use a wristwatch in another way by pointing the hour hand at the sun, then determine the mid-point between the hour hand and 12, and THAT is South. It works whether AM or PM during daylight hours. My thoughts in the past have always been oriented to North, as maps are indexed that way, however, thinking “South” allows me to keep the sun in sight during daylight hours, and allows me to determine direction faster. So, consider thinking “South” next time you’re on an outing and the sun is shining.
