Sun loses 4 million tons of mass per second





According to Einstein, the energy of the physical object is equivalent to its mass (E = mc2). From this one can calculate how much mass lost due to the sun that emits light, ie. E. Energy 4 million tons per second. But it's quite a bit, considering its size and weight: at this rate our star gets rid of all of 1% of its weight for 160 billion years. Solar winds, forcing the substance of the sun to overcome gravity and fly it into space, in fact, are much more dangerous in terms of the destruction of stars.
