I just ran the numbers and, assuming that she can jump up 1 foot on earth and that the asteroid is spherical with a density of 1500 kg/m^3 (making it a C-Type), it would have to have a mass greater than 1.4 x 10^14 kg to prevent her from jumping off it.
Equations look truely terrible in text format. I wrote them out as a MS Word file, but, understandably, the site won't let me attach a doc to a thread post. If anyone is interested in checking my numbers, e-mail me, and I'll be happy to send it to you.
