What is the length of day and night on the equator?

The length of day and night on the equator exceeds 20000 km and 12 hour respectively.

The length of day and night on the equator is always equal. Because at any time, the twilight line divides the earth into two parts, that is, half is day and half is night, and both the equatorial center and the twilight line are the center of the earth's sphere, so the twilight line divides the equator into two equal-length semicircles, so any day and night on the equator are equal-length.

The equator is the dividing line between the northern hemisphere and the southern hemisphere, and it is also the zero latitude on the earth. In a year, the equator has two direct sunlight, so the equatorial region belongs to the tropics, and the weather is hot and the temperature is very high all the year round. The center of the equator coincides with the center of the earth. It is also the longest latitude circle on the earth, with a total length of over 40,000 kilometers.

The equator passes through Gabon, Congo, Zaire, Uganda, Kenya, Somalia, Maldives, Indonesia, Ecuador, Colombia and Brazil. In these countries, people use different symbols to represent the equatorial line. For example, in Congo, people use many small stone pillars arranged in a straight line to represent the equatorial line. These small stone pillars are called equatorial piles.
