# Is the sun in danger?

Classical Mechanics Level pending

Solar energy reaches the earth at the rate of about $$1.4 \text{ kW}$$ per square meter of surface perpendicular to the direction of the sun. By how much does the mass of the sun decrease per second owing to this energy loss?

The mean radius of the earth's orbit is $$1.5 \times 10^{11} \text{ m.}$$
