It's "axis" is probably the answer, but the question doesn't make complete sense.
The equator is an imaginary line which indicates where the middle of the earth is and it goes around.
The imaginary line through Earth's poles is called the axis. It is an imaginary line that Earth rotates around.
The axis
the equator is the imaginary line around the earth.
The imaginary line between the poles of the Earth around which the Earth spins is called the "axis of rotation".
Its axis The earth rotates around its axis - an imaginary line running from the North Pole through the centre of the earth to the South Pole. It rotates around this line once every day. it is this rotation which causes day and night. axis
The imaginary horizontal line that goes around the middle of the earth is called the equator.

the equator ========= There are many imaginary lines around the Earth. In fact, there are an infinite number of imaginary lines. The two main types of imaginary lines are parallels of latitude (of which the Equator is one) and meridians of longitude.
