The 'new' sizes and gravities are just fine...earth has a notably hefty iron
core, which a planet of Jaern's size can do without and thereby maintain its
lower gravity.  Kris had it right; mass, not size, determines gravity.  Pinhead
size points with the mass of earth have its gravity...take earth's mass and
'fluff' it a bit and you can get Jaern with earth-g...take away some mass and
keep the fluffing, and you get Jaern.

BTW, planets tend to get -very- f'ed up rotational velocities when tagged with
large objects, such as planets or moons.  I'm surprised at Jaern's speed if it
were actually hit.  I believe Torandor and its moon hit one another, not Jaern,
once Jaern's gravity messed them up...if not, Jaern otter be spinning like a top
by now.
