SUMMARY
The center of mass of a system composed of two photons can be defined using the concept of center of momentum, despite photons having zero rest mass. In a center of momentum frame, both photons possess equal energies and travel in opposite directions, maintaining equidistance from the center. To determine the center of mass in a laboratory frame when the photons have different energies, one must apply Lorentz transformation equations. The total momentum (p) of the system must equal zero for the center of momentum to be established.
