Pluto's Expanding Atmosphere Confounds Researchers
http://news.sciencemag.org/sciencenow/2011...onf.html?ref=hp Could these be evidence of geyers like on Triton? |

may someone with some time to spare and Pluto and Charon masses and distance at hand compute where the L1 lagrangian point would lie?
I was thinking: how much would the atmosphere of Pluto need to inflate before mass transfer to Charon begins? this is what happens on some classes of double stars including some kinds of supernovae |

I get L1 for Pluto lying around 5050km from the centre of Charon, 14520km from the centre of Pluto. About 4/5ths of the way from Pluto to Charon.

I get 5210 km from Charon. Wonder where the discrepancy comes from? The options seem to be: 1/ Listed masses for Charon and Pluto 2/ Excel 3/ My maths I err towards 3/ in this instance - but whats a hundred miles between results? ;-) Hmmm. Andy |
