It would be highly unusual and considered a very literary or strained metaphor. Words like 'vast distance', 'immense gap', or 'worlds apart' are more natural.
For a celestial object, its polar distance (from the north celestial pole) is equal to 90 degrees minus its declination. If declination is +50°, polar distance is 40°.
It describes a very specific technical measurement relevant only to specialists in navigation, astronomy, and earth sciences. Most people never need to refer to this concept.
