Its perimeter
It is called its bounds. In the case of 2 dimensional objects, it is part of the perimeter.

The out edge of a cup is called the 'Rim'.
brim
The term that describes the outline of an object is "contour." It refers to the outer edge or silhouette of a shape or form. Contour lines are often used in art and design to define the shape and structure of an object.
The outer edge means the furthest most point from the center. The outer edge is usually the end of the object before the dropping off point.
An edge can be of a shape in a plane while a rim suggests a three dimensional object with a defined outer portion. In geometry and topology "edge" has a definition which is very precise. "rim" haa no such specific determination.
