From planet earth to another planet earth?

Yes, Earth is the largest of the 4 rocky planets, but the 4 gas giant planets are much larger.

It is not a star, an asteroid... why not a planet.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
