Polaris

I chose this star because it is the current pole star for the Northern Hemisphere and since it is very close to the north celestial pole, it has been a trustworthy navigational tool for centuries for sailors, astronomers, and travelers; it has even been deemed :the most practically useful star in the heavens". It is widely known as the alpha star in the constellation Little Bear and marks the end of the handle in the Little Dipper. In addition, it is the only star in the sky that appears stationary, and is only visible in the Northern Hemisphere, where it serves as the previously mentioned navigator's benchmark.
