Launch mass of Rosetta was 3000kg (3Mg). The lander mass is 100kg. Only counting the mass of the lander and not counting the mass of the Rosetta craft that got it there is like only counting the mass of the astronaut and not the mass of the ship. You still have a large multiple, but 30 times less than you calculated.
So only 500X? Oh, well then. Let's get going tomorrow!
