Definition[edit]

Technically, I've also seen definitions that indicate that the star does NOT need to be visible to the observer to be circumpolar. Could somebody fix or clarify this? It is unusual for a scientific term to not match its latin origin.

(Circum=Around/Ring & Polar=the Poles) (There are no Apparens/Visibilis/Observare/or other latin roots to indicate visibility)

The stars that are circumpolar at one latitude still continue to circle the poles even if they are continuously below the horizon at a different latitude. They do not rise and fall like the non-circumpolar stars which do not circle the pole, they are merely hidden to the observer. If circumpolar does not apply to them, they seem to have no word that does apply.

Suicircumpolar or Visicircumpolar would indicate a point of view.

Alternatively, circumpolar would represent visibility only if a world like exocircumpolar, extracircumpolar, or hypocircumpolar existed to indicate outside the viewed circle.

Regardless, to be a useful article, it should clarify proper usage by referring to related terms that are NOT circumpolar. --- "Such stars neither rise nor set, but hover just above the horizon." -- from which point on Earth? Wouldn't Polaris be almost overhead when one is standing at the north pole? -- Tarquin

yes, it needs some clarification i guess... I g2g and Im not sure how to word it. Lir 17:07 Oct 30, 2002 (UTC)

When I was north of the Arctic circle I glanced in the usual spot for the Big Dipper (Ursa Major) and was astonished find it missing, or as it turned out, to see how high it was. And then I craned my neck further to find Polaris. I suddenly felt like I was on a round planet and grasped celestial navigation in a way that no amount of semi-diligent study had ever given me.
