The imaginary line that circles the middle of the earth is called the equator.
A circle of constant longitude passing through a given place on the earth's surface and the terrestrial poles.
The imaginary longitude 0 is called the Prime Meridian. It serves as the starting point for measuring longitude and is located in Greenwich, London, UK.
A meridian is an imaginary line that runs from the North Pole to the South Pole on the Earth's surface. It is used in navigation and to indicate longitude. The prime meridian, at 0 degrees longitude, passes through Greenwich, England.
The Earth's rotation refers to the way it spins around its axis, completing one full turn approximately every 24 hours. This rotation is responsible for the cycle of day and night. Additionally, the Earth's revolution refers to its orbit around the Sun, taking about 365.25 days to complete one full orbit, which results in the changing seasons.

equator comes to mind
I think it's the tropic of Cancer.
[muh-rid-ee-uhn] -noun a great circle of the earth passing through the poles and any given point on the earth's surface. b. the half of such a circle included between the poles.
At a given distance from the Sun, only at a very specific spead will it go in an exact circle. And that perfect circle will soon be disturbed by gravitation from other planets, comets, etc.
The imaginary line that follows the curve of the Earth and is the shortest route for pilots is called a great circle route. This route is the most efficient way to travel between two points on the Earth's surface, as it represents the shortest path over the Earth's surface, given its spherical shape. Pilots often use great circle routes to save time and fuel during long-distance flights.
Physically, this may be an impossibility, given the material you'd be required to drill through, including the Earth's molten core.
These are known as lines of longitude or meridians
To calculate the phase constant in a given system, you can use the formula: phase constant arctan(imaginary part / real part). This involves finding the ratio of the imaginary part to the real part and then taking the arctangent of that ratio.
A circle of constant longitude passing through a given place on the earth's surface and the terrestrial poles.
Method acting involving living truthfully in a given set of imaginary circumstances
"Lines of Latitude" and "parallels" are both used. Please note that the "lines" are imaginary; you'll never see one on the ground. Just on a map.
