What are constellations?
Constellations are a group of stars that seem to resemble something familiar to those who named them. They are not real objects but are just patterns that we see in the sky. Constellations have imaginary boundaries formed by connecting the stars. All of the stars within those boundaries are labelled with the name of that constellation.

Importance of Constellations
1) Farmers         - to remind them of planting and harvesting seasons.
2) Astronomers - to map the sky. 
3) Explorers      - for navigation and determine the direction 
                            especially on the ocean.
