Equator is the longest latitude.
The Equator is the longest circle of latitude
The equator ... the line that contains every point on Earth with zero latitude ...is the longest parallel.
All lines of longitude are equal. The longest line of latitude is the Equator.
The longest parallel of latitude is the one defined as 'zero degrees', known as the "Equator". All meridians of longitude have the same length ... 1/2 of the earth's polar circumference.
The equator is located at 0 degrees latitude, which means it is located at the circunference of Earth. Earth is shaped like a sphere, and the circumference of a sphere is the longest distance around any part of the sphere. Therefore, this makes the equator the longest line of latitude.
The longest line of latitude is the equator (0°).
No, it's the longest latitude.
The locus of all points of zero latitude ... sometimes also known as the "Equator" ... is the longest parallel of constant latitude. It's length is the equatorial circumference of the earth ... roughly 24,900 miles (40,073 km) .

The lines of longitude are all the same length. There is no longest line of longitude. Now, if you mean latitude, then that would be the equator.
The fact that it is invisible(?)
