The following statements describe constellations:
- Constellations can be used for navigational purposes.
- Constellations are named patterns of stars seen in the night sky.
- Constellations are used by astronomers to locate objects in the night sky.
The first statement is misleading; while constellations often include some of the brightest stars, they are not exclusively made of the brightest stars but rather a pattern of stars. The third statement is incorrect because constellations can be observed in both the Northern and Southern Hemispheres.
