It is not visible at or south of the Equator.
Theoretically , it would appear on the horizon.
Remember the Pole Star is overhead at 90 degree N. (The North Pole). So when you have reached the Equator, your angle has changed by 90 degrees because you are now at 0(zero) degrees. So viewing the sky Polaris (Pole Star) will has now changed its angle by 90 degrees. So from being overhead, a 90 degree angle will be the horizon.
You don't see Polaris at the Equator, because of the density of the atmosphere, dust and dirt and moisture in the atmosphere.

As you approach 0 degrees latitude (the equator), the North Star becomes lower in the sky. The North Star is located directly above the North Pole, so as you move further south towards the equator, it appears closer to the northern horizon. At the equator (0 degrees latitude), the North Star would be right on the horizon and not visible.
To determine if a star is circumpolar (never sets) when viewed from a northerly latitude, you can use the formula: 90° - latitude + declination >= 0. If the result is greater than or equal to zero, then the star is circumpolar from that latitude. The declination is the star's angular distance north or south of the celestial equator.
If every star in the sky rose and set except for Polaris, you would be at the North Pole. Polaris, also known as the North Star, is located almost directly above the North Pole, making it appear stationary in the night sky while other stars appear to rotate around it.
When viewed from the equator, the Sun reaches its highest point in the sky at solar noon, which occurs when it is directly overhead at 90 degrees. This happens during the equinoxes, around March 21 and September 23, when the Sun is directly above the equator. During these times, the Sun's altitude is maximized, resulting in the shortest shadows.
Directly overhead.

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 the result is greater than or equal to zero, then the star is circumpolar from that latitude. The declination is the star's angular distance north or south of the celestial equator.
The northern pole star "Polaris" is visible in the sky to an observer located anywhere on earth between the equator and the north pole, i.e. anywhere with a north latitude. There is no similar southern pole star.
-- Direction: Due north.-- Altitude above the horizon: Same angle as your latitude. Very roughly 30-45 degrees in the US.
The sky is a pinkish-red when viewed from mars because the atmosphere causes a tint.The sky would be pink when viewed from Mars.

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.)
The north star.
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.
