Parallel axes theorem​

Explanation:

The parallel axis theorem can be used to determine the moment of inertia or the second moment of area of a rigid body about any axis, given the body's moment of inertia about a parallel axis through the object's center of gravity and the perpendicular distance between the axes.

(I = I_c + Mh^2)

Where, I = moment of inertia of the body; I c = moment of inertia about the centre; M = mass of the body; h 2 = square of the distance between the two axes

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
