Hi all, I just finished a NASA training session on the Rosetta mission. During the Q&A someone asked how gravity on the mission's target (Comet 67P) compares to Earth's. The answer was around 1/10,000. So if when I stand on a scale here on Earth it reads 63 kg, I *think* on 67P it would read 6.3 grams (about the same as a US 25 cent piece). Have I got that right? Wanting to make sure I've got the decimal in the right place. patrick
