Bottom line: Every star rises and sets as seen from the Earthâs equator, but no star rises or sets at the Earthâs North and South Poles. Instead, as viewed from the poles, every star is circumpolar. Between the equator and the poles â¦ youâll see some circumpolar stars and some stars that rise and set daily.
In short, in the end, the nuclear furnace at the center of every star begins to overheat. To 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.
