Consider a star whose mass is 1.78 × 1029 kg (approximately equal to Sun). The star loses mass at a rate of 1.14 × 1019 kg per year due to fusion. It can sustain fusion until about 0.15% of its total mass is converted into energy and then stops. Determine the estimated lifetime of the star, expressed in million (106) years.
