We have a sun that is like ours, does not matter I think because of scaling. That sun is completely encased in large rock formations like that of a planet. Basically if you replace the core of a planet with a sun.
Obviously I want it to be naturally formed planet but the focus on the theoretical aspect of it is more important since the universe is a big place it's enough to know it could happen.
I understand there are complications regarding other aspects but I'm only focusing on one thing here and will ask later about other problems. I want it later to orbit a sun and have an atmosphere...etc But again I just wanna focus on one aspect:
Is such a thing even theoretically possible?
And what type of real or theoretical material would be used? to achieve that idea?
I understand that those are two things, do they need to be broken? But I'm worried that it would get closed if the question has a simple yes or no answer.
It must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to have enough gravity to force it into a spherical shape. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.
However I'm only interested in figuring out this first step now, could it be real?
I'm well aware that the gravity of the sun is huge. Even one like ours has a lot of gravity. So. This is part of the question. I mean that what type of material could withstand such gravity
Obviously, the sun also outputs a lot of energy. So the planet will have to find a way to handle that if possible.
I'm content if it not even theoretically possible. But I'd just love to know more on why.
I will ask about an atmosphere later, as well as if it can orbit a star or not...etc Just want it to be focused.
