Ok, admittedly escape velocity will be a little different. In my examples above the escape velocity on the iron planet will be 1.7 times higher than on Earth, and on the water planet it will only be about 20% that of Earth's escape velocity, but it's close enough that for say, a fiction based on the Star Wars universe it will be much closer than anything actually used in the series.
