This means that different parts of the globe are tilted towards the sun at different times of the year (or at different times during its orbit).

How do you calculate the lifetime of the Sun? (Advanced

where M sun is the total mass of the sun, 2 x 10 30 kilograms. We therefore can calculate that the total energy the sun has to burn is around 1.3 x 10 44 Joules. Dividing 3.8 x 10 26 Watts (the rate at which the sun is giving off energy) into this number gives an approximate value of 10 billion years for the sun's lifetime. SUN - Interesting Facts About SunAll the coal, oil, gas, and wood on Earth would only keep the Sun burning for a few days. An area of the Sun's surface the size of a postage stamp shines with the power of 1,500,000 candles. The energy being emitted from 1 square centimeter of the Sun's surface is enough to burn 64 light bulbs of 100 watt.
