As seen from the Northern Hemisphere on Earth, any objects with a declination of approximately 90° - $\phi$, where $\phi$ is the observers latitude, will remain above the horizon all the time. These objects will appear to trace circles around the north celestial pole. The closer an object's declination is to +90°, the smaller the circle it traces. The star Polaris is currently quite close to the north celestial pole and is known as the North Star. Likewise, the constellation Usra Minor (the Little Dipper) never sets.

Other constellations, such as Orion (and the stars Belegeuse and Rigel) have declinations of only about +7.5°, so from New England they appear to rise and set each night.

Finally, stars with declinations below about -90° + $\phi$ do not rise at all.
