I think it's called a contigous region, or maybe a bounded area, something like that.

To close a path in GIMP, select the Path tool from the toolbox and click on the last point of your path to connect it to the first point. Alternatively, you can right-click on the path in the Paths dialog and choose "Close Path." Once closed, you can fill or stroke the path as desired.
A closed path is a continuous route in which the starting point and the endpoint are the same, forming a loop without any breaks. In mathematics and computer science, it often refers to a circuit or a polygon that encloses an area. Closed paths are significant in various fields, including geometry, graph theory, and physics, where they can represent cycles or loops in systems.

Circle.
That path might be called a circuit. If the path is complete, it's a closed circuit.
The path of Earth's orbit in the shape of an elongated closed curve is called an ellipse. An ellipse is a type of geometric shape that resembles an elongated circle, with two focal points inside the curve. This shape is a result of the gravitational forces between Earth and the Sun.
That is called orbital motion. it is the closed path that one object in space follows around another object, typically due to the force of gravity.
A closed path through which a current can flow is called a circuit. Electric Circuit:)
That is called a switch.
That's called the "distance" between the points.
Traveling in a closed path means that you start and end at the same point without leaving the path. In other words, you move in a loop or circuit, returning to your initial position after completing the journey.
To orbit the object.
That would be called a 'circuit' or 'closed circuit'.
