A polar projection of the earth shows a pole (north or south, depending on the projection) at the center of a circular map. The equator is the circumference of the circle.
Polar Area
Polar projections are often made in what is called the Azimuthal Equidistant Projection. The projection would be made tangent at the north pole, or at the south pole. These projections allow you to make linear measurements from the pole to any point on earth. These measurements are the shortest distances from the pole to the points and can be directly compared to one another. A polar projection shows the poles; I learned it in my science class.

Mercator:Mercator projection works very poorly in polar regions and becomes undefined at the north and south poles. Historically Mercator is interesting because it is one of the oldest map projections to be used. Christopher Columbus used the Mercator projection in his travels to the new world. This projection is often used in navigation because any straight line is a rhumb line (a line of constant direction). Parallels of latitude and longitude are straight. Features increase in size as the map approaches the poles. Areas and shapes of large areas are distorted. Distortion increases away from the equator and is extreme in polar regions. However, being a conformal projection, angles and shapes within any small area are essentially true.
The Mercator Projection distorts the size of large objects from the Equator to the poles. It was named for Flemish map make Gerardus Mercator.
The polar projection, specifically the azimuthal polar projection, stretches out the area around the North and South poles. This type of projection represents the polar regions accurately but distorts the size and shape of landmasses as one moves away from the poles. Consequently, countries and continents near the equator appear smaller than they actually are, while those near the poles appear much larger.

Celestial Equator
The cylinder map projection shows a high degree of distortion at the poles. This distortion causes shapes and distances to be exaggerated in polar regions, while the equator remains relatively accurate.
The polar regions are often represented using the azimuthal polar projection. This projection centers on one of the poles, allowing for an accurate depiction of the area surrounding it. It is particularly useful for navigation and for representing phenomena such as weather patterns in polar areas. The azimuthal polar projection distorts shapes and sizes further from the center, but provides a clear view of the polar regions themselves.

No, the equator is not a polar region. The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres, while the polar regions are located near the North and South Poles. The equator is known for its warm and tropical climate, while the polar regions are characterized by cold temperatures and ice.
A type of projection that usually shows the poles is the polar projection, which focuses on the Earth's polar regions. It is often used to study and analyze features near the North and South Poles.
