    Thank You Emily as always 😀

    This proves how well the Rosetta mission is proceeding, if a final landing site for Philae can be decided upon as early as Friday 12th September 2014.

    incredibly early actually, I expected late October at the very earliest, possibly almost up to the week prior to the landing date.

    Wonderful news 😀

  • Andrew R Brown says:

    Sorry meant Monday 15th September 2014, my bad, still incredibly early though 😀

  • For a public presentation I have to give I wonder if you could tell me how high the gravitational acceleration is on Churyumov-Gerasimenko.
    An object of equal mass on the Moon weighs only 16.6% of its weight on Earth. How does that compare to the comet?

    Thanks in advance for your reply!

  • Loren Petrich says:

    That is very easy if one ignores the comet’s nonsphericity. Its mass was recently measured from its pull on Rosetta. It is about 10^(13) kg. From the size of the comet, I’ll use a distance of 2 km from its center. That makes its acceleration of gravity about 1.7*10^(-4) m/s^2, or 1.7*10^(-5) times the Earth’s. Its escape velocity is about 0.8 m/s^2.

    On the subject of the comet’s gravity, how much progress has been made on getting its gravity’s nonsphericity? Or is Rosetta still too far away to get much on that? That ought to provide some clues about its mass distribution.
