the equator is the world's line

Hello friend steemit little about the equator line that became the world line

The equator is a line of imagination drawn in the middle of the planet between two poles and parallel to the planet's rotational axis. This equatorial line divides the Earth into two parts of the northern hemisphere and the southern hemisphere. The equator latitude is 0 °. The length of the equatorial line of the Earth is about 40,070 km.

At the equator, the sun is just above the head at noon at the equinox. So the duration of the day is the same throughout the year approximately 12 hours.
