How to Find the Cassiopeia Constellation

Looking at the night sky to find constellations can be both fascinating and educational. Although the sky changes with the seasons, some constellations remain visible year-round. These circumpolar constellations rotate around Polaris -- the North Star -- in the Northern Hemisphere. Cassiopeia belongs to the group of circumpolar constellations. The height of Cassiopeia in the sky will depend upon the latitude of your location. For example, if your location is 40 degrees north latitude, the North Star will appear 40 degrees over the horizon in the night sky.

Instructions

      Locate the Big Dipper in the sky. Depending on your location and the time of year, the Big Dipper may be higher or lower relative to the horizon. The Big Dipper is the highest during the time between late winter and the beginning of summer. As summer progresses, the Big Dipper gets lower in the sky. The Big Dipper consists of seven stars; three stars make up the handle of the dipper, and four stars make up the dipper. Follow a straight imaginary line extending out from the two stars that form the outside edge of the dipper, and you will find Polaris.

      Notice the stars connected to Polaris. Polaris is the star on the end of the Little Dipper's handle. The Little Dipper consists of three stars as the handle and four stars as the dipper.

      Extend the imaginary line further (still using the two stars on the ladle of the Big Dipper as your base). After you have extended the line through Polaris, further extend it about the same distance in the same direction. There, you will find Cassiopeia. This constellation consists of five stars that resemble a flattened "W" or "M."
