Polaris was referenced in Nathaniel Bowditch's 1802 book, American Practical Navigator, where it is listed as one of the navigational stars. [39]
Guide to using Big Dipper to locate Arcturus, Spica, and Polaris. Not only are the stars in the Big Dipper easily found themselves, they may also be used as guides to other stars outside of the asterism. Thus it is often the starting point for introducing Northern Hemisphere beginners to the night sky:
Ursa Minor (Latin for 'Lesser Bear', contrasting with Ursa Major), also known as the Little Bear, is a constellation located in the far northern sky.As with the Great Bear, the tail of the Little Bear may also be seen as the handle of a ladle, hence the North American name, Little Dipper: seven stars with four in its bowl like its partner the Big Dipper.

Sigma Octantis is the closest near naked-eye star to the south celestial pole, but at apparent magnitude 5.47 it is barely visible on a clear night, making it less useful for casual navigational or astronomy alignment purposes.

The former Quadrans Muralis constellation was located near the Big Dipper. While meteors can appear to stream from this point in the sky, people should be able to see shooting stars across the ...
To find Polaris, from a point in the Northern Hemisphere, face north and locate the Big Dipper (Plough) and Little Dipper asterisms. Looking at the "cup" part of the Big Dipper, imagine that the two stars at the outside edge of the cup form a line pointing upward out of the cup.
