The path where a planet moves around the sun is called an orbit.
With a curved path you have to slow down to curve as with a straight path you dont have to slow down you can do as fast as you need to go to get threw it.
The path of electricity is called a circuit.
centripetal force
The earth is traveling counter clockwise around the sun.
This is an orbit.
asteroid belt
Each planet moves in its own elliptical orbit round the Sun, then and now.
The planets around the sun move in a path called an orbit. This orbit is the result of the gravitational pull between the planets and the sun, causing them to travel in a curved path around the sun.
Planets rotate around the sun. The path is not really circular for planets, it is actually ellipsoidal.
They don't. They move in ellipses around the Sun.
"orbit"
orbit, which is the curved path that a planet takes as it revolves around the sun.
Their own gravity disables them to lose path in their orbit and makes their path steady.
orbit
The path on which planets travel is called their orbit.
There path is not imaginary, so the answer is no.
The gravity of there star keeps them on path and a planets moon is sun around by its planets gravitational force
