The Equator is the region on earth can you observe all the stars in the sky over an entire year.
The equator is a circle of latitude, about 40,075 km in circumference, dividing the Earth into two northern and southern hemispheres. It is an imaginary line located at latitude 0 degrees, between the North and South poles.
In spatial geometry (3D), as applied in astronomy, the equator of a rotating sphere (like a planet) is the latitude (circle of latitude) at which latitude is defined as set to 0°. It is an imaginary line on the sphere, equidistant from its poles, dividing it into the northern and southern hemispheres. In other words, it is the intersection of the sphere with a plane that is perpendicular to its axis of rotation and lies between its geographic poles.
Above and near the equator, sunlight at noon appears almost directly overhead (no more than 23° above zenith) every day, all year round. Therefore, the equatorial region has quite stable daytime temperatures all year round.
