The 10 Billion Years Old ‘Guy’

Sun is currently five billion years old and will ‘live’ for another five billion years!

After about FIVE BILLION YEARS, the Sun will grow 100 times larger than it is now [and will eat all planets upto Mars (including Earth)]!

The reason behind this is ‘Nuclear Fusion‘. In the core of sun (and every star), lighter elements are being converted into heavier ones. This produces a quite large amount of energy.

This is the same principle behind the ‘Hydrogen Bombs‘ or ‘Thermonuclear Bombs‘.

The ‘nuclear energy’ release by this nuclear fusion opposes the ‘self-gravity’ and increases the size of sun (and any other star).

This makes it larger and larger with time.

It will firstly become a red giant, and when all the fuels will run out, it will only leave its core (as its ‘dead body’) behind in the form of a ‘WHITE DWARF’.
