Circumference.
The line around a circle is called the circumference. It is the distance measured along the outer edge of the circle. The circumference is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the circle.

Answer The length around a circle has a special name called circumference. Circumference = pi times diameterThe circumference is the distance around a closed curve. Circumference is a kind of perimeter.The circumference of a circle can be calculated from its diameter using the formula:C = pi times dOr, substituting the diameter for the radius:C = 2 r times piwhere r is the radius and d is the diameter of the circle, and π (the Greek letter pi).Distance around a circle
If you mean the trajectory of the planets around their parent stars, it is called the orbit, and it is not a circle but an ellipse
A straight line from the center to the edge of a circle is called a radius. The radius measures the distance from the center to any point on the circumference of the circle.
