How to find the center of an object?

I have a black and white image after binarization. After that, I get one object with an irregular shape. Link to this image below. How can I insert this object into a circle? or How can I find the "center" of this object?

You can find the center of gravity of pixels using a simple formula, which is the sum of the x coordinates divided by the number of points and the sum of the y coordinates divided by the number of points (I mean white dots).

Then you can draw a circle centered at the center of gravity with the radial half of the maximum distance between the points.
