There is no such line. The imaginary line through its centre is the axis, which the Earth rotates around; the imaginary line an equal distance from the poles is the equator. Neither make it spin - that is caused by momentum from the planet's formation.
The imaginary line around which the earth turns is its axis.
it's a segment.
A planet's axis is the imaginary line that the planet rotates around, like spinning top.
The Earth revolves around its axis, an imaginary line running through the centre of the Earth from the North pole to the South pole. As an orbiting planet, its orbit takes it around the Sun once every year.
Anything that rotates has an imaginary line that it appears to rotate around, and that's what's called the "axis". Since the sun definitely rotates, there's an imaginary line through it that it seems to rotate around, and it's completely proper to refer to that imaginary line as the sun's axis.
the equator is the imaginary line around the earth.
The equator is an imaginary line which indicates where the middle of the earth is and it goes around.
The imaginary line between the poles of the Earth around which the Earth spins is called the "axis of rotation".

The equator
The line your referring to is the Equator.
Earth spins on a imaginary line called an Axis that's what it rotates on aswell. An axis has an angel for the Earth to spin on. An Equator is another imaginary line.
