Marduk - Reaches Adventure

[Solomani666]

I noticed that Marduk is a size 3 planet.
Given an average density this plant should have a gravity of about 0.25 G.
Based on the reviews I have read, this seems to be an ignored factor in the "Marooned on Marduk" adventure.
Does the planet have an extremely dense core?
Did I overlook something?
What is the G rating of the planet?

Whatever you want it to be. Given the denser ATM rating, I would say it is a bit denser than "average", maybe 0.5G? Of course, there are no actual details given, so you can make it up.
