Stumped: How can I get a huge Earth-like planet?
I hope this isn't too broad.
I would like an Earth-like planet for November's NaNoWriMo that is just enormous, but plausible.
Then I started to get into material composition, proximity to the star, trying to achieve the right densities - well, you get the idea.
I'm trying to have 10x the radius of our current Earth, but with similar gravity (ugh) and at least somewhat similar climate and surface conditions; I do not need to have life on this planet, but minerals and liquid water are important to us. Not quite a Jupiter-sized planet, but much larger than ours. Other factors can be modified.
