Yes. The North Star is aligned with the celestial north pole.
'Declination' of +30
Half. The other half is south of the celestial equator.It depends on the where you're looking from (at the equator it is half and half). If you are at latitude 30 degrees north, then about 2/3 of "your" sky is north of the celestial equator (30 degrees north means that you are one-third of the way north from the equator to the North Pole.)
Mintaka in the Belt of Orion
the angular distance of a place north or south of the earth's equator, or of a celestial object north or south of the celestial equator, usually expressed in degrees and minutes
Yes. For any point on Earth that is north of the equator, the north celestial pole is above the horizon.
If you are standing at the north or south pole, then the celestial equator coincides with your horizon. At other latitudes, half of the celestial equator is above the horizon, and half is below it.
SOUTH
No. Argenrtina is entirely south of the equator, so the north celestial pole is not visible.
Yes. "Declination" on the celestial coordinate system is the counterpart of "latitude" on the terrestrial coordinate system. Positive and negative declination correspond respectively to north and south latitude.
