No, due to the shape of the earth you can not see the North Star below the equator.
The North Star is almost directly over the north pole, so it cannot be seen south of the equator.
It means that you are traveling south across the equator.
The elevation of Polaris (the North Star) above the Northern horizon is almostequal to the North latitude of the place where you are when you see it.That means that when you stand on the Equator, the North Star is exactlyON the Northern horizon, and if you stand anywhere South of the Equator,the North Star is always BELOW the horizon.But . . .Everybody in the Southern hemisphere CAN see the SOUTH pole of the sky,which nobody in the Northern hemisphere can ever see.Sadly, there's no bright star anywhere near the South pole of the sky,to mark it the way Polaris marks the sky's North pole for us.
If you see the North Star go below the horizon, assuming you have identified it correctly, then you would have to be moving south across the equator.
Yes. The North Star is aligned with the celestial north pole.
Yes but only but only to a few hundred miles south of the equator and seen on the horizon.
Latitude measure North to South. This is a much more appropriate answer. Latitude measures the angle between your horizon and a polar star. Which in turn provides a measurement in degrees north or south of the Equator.
There are completely different constellations on South sky. Behind the equator there is no Northern star visible.
You can see the North Star almost anywhere in the northern hemisphere, starting a few degrees north of the equator.
People use the north star as a navigation tool. Everyone knows that the direction of south will be the opposite of the star. East and west will also be able to determine.
'Declination' of +30
From any location north of the Equator: The north star (Polaris) is in the sky, always due north of you, and always as many degrees above the horizon as your latitude north of the equator. It makes no difference what time you look for it, or where you are in an east or west direction.
