SUMMARY
The mass of an exchange particle that could hold the moon together can be derived using the formula for the range of an exchange particle, R = ħ/(2mc), where ħ (h-bar) is 1.054 x 10^-34 J·s, m is the mass of the exchange particle, and c is the speed of light. Given the moon's radius of 1737 km, the range must be equivalent to this radius for the exchange particle to effectively hold the moon together. Understanding the Yukawa potential is essential for applying this concept to the problem.
