Since google has transformed itself from a noun (meaning 10^100)
into a verb, I googled up the mass of Jupiter at 1.9E27, and I
already knew the mass of the sun is about 2E30, so Ms/Mj = 1050
so square root of that is about 32, so the Sun/Jupiter L1 would
be 32 times closer to Jupiter than the sun, and I also recall the
distance from the sun to Jupiter is about 5.2 AU, so the L1 is
about .16 AU sunward, or about 24gigameters out from Jupiter.

Cool site, thanks! spike
