Is it possible for an earth-like planet to be the size of our sun?

The earth is about 4 times denser than the sun. If you scaled it up to the size of the sun, you'd have a sun-sized ball of iron and other elements. The force of gravity would likely collapse the ball. It depends a little bit on the exact composition, and what you consider to be the boundaries of the sun.
