Not to be that guy... But stars and planets definitely have the potential to affect all of our lives, just not in any positive w-- the sun goes supernova
Our sun will never go supernova because it's too small for that. As hydrogen runs out, it will grow to a red giant by burning off the helium it produced and will expand to about Mars' orbit. When the helium runs out too, it will then collapse to a white dwarf and release dust clouds into what formerly was our solar system and then it just huffs out like a candle in the wind.
To go supernova, our sun would need about 10 times its mass.
