re: Earth Like Solar Systems Rare?

"The simulation traces the creation of a planetary system from almost beginning to end, for the first time, and suggests that our solar system started with just the right mass to become a relatively orderly place in the universe.

"You have to have the conditions just right," Thommes told Space.com. "They have to be in a fairly narrow range.""

Note: Inconsistant with the idea that intelligence is common idea if you believe an earthlike planet is needed.

Now I guess Phil can't use this in support of the rare Earth arguement since he doesn't believe in simulations, but I do and can."

Can you run a simulation of our solar system that will predict all bodies say larger than our Moon.

In other words can they predict with any accuracy the number of undiscovered objects in the Kuiper Belt and/or
Oort cloud. Related to this, can it be predicted from simulation how much mass [in form of asteriods, dwarf planets, planets, and/or gas gaints] have been ejected from our inner solar system?

Does anyone know how much matter in the form of asteroids, dwarf planets, planets, and/or gas gaints has been added to the Sun [say from the time the Sun first began it's life as a star].

And does anyone know what the smallest planet which could support life- e.g. Mars' size or Moon size.
Would Pluto system be habitable is it was further out than Venus and closer than Mars?
