It has been established that due to radiation, the Sun loses 1.3 * 10 ^ 14 tons annually. Calculate the time during which the mass of the Sun will decrease by 1% at the same rate of radiation. The mass of the Sun is now 2 * 10 ^ 30kg.

One percent is 2 x 10 ^ 28 kg. t = 2 • 10 ^ 28 / 1.3 * 10 ^ 17 = 1.5 • 10 ^ 11 years.
