NettetTo put numbers on this, when the Sun was formed 4.5 billion years ago it was about 30% dimmer than at present. At the end of the next 4.8 billion years, the Sun will be about 67% brighter than it is now. In the 1.6 billion years following that, the Sun's luminosity will rise to a lethal 2.2 L o . (L o = present Sun.) NettetThis is called the “Total Solar Irradiance,” or TSI.
