An imaginary line that runs through the center of a planet and its poles is called its axis.
Or possibly a diameter, in regards to the planet's dimensions.
It's called the Equator.

A planetary axis is the imaginary line or pole through the center of the planet which defines the point around which the planet rotates, or spins.
The orbit of a planet around the sun is called an ellipse.
There would be no orbit. You have to have a body to orbit around and without a star or other planet to orbit around, it would just move in a straight line.
The equator is an imaginary circular line around the entire earth, with the center of the circleat the center of the earth.Any circle that has its center at the center of the earth divides the earth's surface exactly in half.
Prime Meridian.
what does earth spin on besides a inmaginary line? ============== Planet Earth rotates on its axis.

A planet's axis is the imaginary line that the planet rotates around, like spinning top.
The Iron Curtain, a term invented by the British Prime Minister Winston Churchill.
first off it's not imaginary its an orbit another thing the earth spins on is it's axis

If there were no force attracting the sun and a planet toward each other, then the planet would move at a constant speed in a straight line, and would just sail away from the sun, never to be seen again. But since there are forces of attraction between them, they're constantly being pulled together, and they wind up both revolving around their common center of mass.
