Answer 1

$\huge{\boxed{\mathfrak\pink{\fcolorbox{red}{purple}{Mr\:Awesome}}}}$

Sun explode :- The Sun does not have enough mass to explode as a supernova. Instead it will exit the main sequence in approximately 5 billion years and start to turn into a red giant. As a red giant, the Sun will grow so large that it will engulf Mercury, Venus, and probably Earth.

Answer 2

Eventually (in five or seven billion years time), the Sun's life will come to an end. Our star will swell up, becoming something called a “Red Giant” star. It might even get so big that it swallows the Earth whole.
