It is not very flattering (although there is still a long way to go ).
Over the next 5 billion years, the temperature and density of the solar core is estimated to increase dramatically . The outer layers will continue to expand and the Sun will turn into a red giant star . Then Mercury, Venus, and possibly Earth, will end up engulfed by our star.
Finally, the Sun will end up as a white dwarf, a dense star that gradually cools down but that, although it does not produce energy, emits light and heat due to its previous solar activity. It will no longer have nuclear fuel.
The planetary nebula NGC 2440 , for example, contains one of the most popular known white dwarf stars. This is how our sun will end in 5,000 million years.
