SUMMARY
The Sun loses mass at a rate of approximately 4.3 x 10^-7 kilograms per second due to its radiation of energy at 3.9 x 10^24 Watts. This calculation is derived from Einstein's mass-energy equivalence principle, E = Δmc^2, where E represents the energy radiated. By substituting the energy output into the equation, the mass loss can be determined over a specified time interval, such as one second.
PREREQUISITES
