What would the radius need to be...
for a 5x mass planet to equal say 1.5 G and what is the max for the planet to still qualify as rocky
I know the formula is Mm/r2 but what little incentive I had for ciphering has left me. I'm guessing, probably twice the radius of Earth would not be too bad. I would like to see it scaled.
Obviously there is a point where the planet density would get pretty mushy, but the consistency of the planet would also be a factor. (a thin crusted planet)
