What are the differences between linear and circular motion. How do you think this concept applies to planetary motion?

linear motion is along a straight line without changing direction where velocity can be constant if the speed is constant and distance travelled is equal to the displacement.
object in circular motion has circular path and changes its position at every point.
here speed can be constant but not velocity change in direction at every point here is same as the direction of the tangent perpendicular to the radius containing the object along its path.
In planetory motion planets move in elliptical orbit(not a circular)
