[DC / Marvel] Why don´t cosmic entities or other supervillians that want to destroy Earth or just make it their own just slighly fuck with the Sun or any other planet in our solar system instead of straigh up attacking Earth?

Like, you could go so much stuff that would be stealthy and quite possibly make Earth inhabitable without confrontation with the big guys.

They're tried all of that at various time and been caught.

That's kind of the point of superpowered people an assorted what not. The spread of their powers is enough to cover almost every conceivable reality and someone somewhere will have a premonition, read tea leaves, pick up on the psychic signature or whatever and go "GREAT SCOTT! SOMEONE IS TRYING TO SLIGHTLY FUCK WITH THE SUN! TO ARMS MEN!"

and then go and wreck them.

Also, the Sun is massive. Anything you could do to even alter it slightly would be massive overkill to do the same thing on Earth. So why not go straight for the target you want?
