But unlike Pluto and Charon the earth moon centre of gravity is somewhere in the earth but not the middle, with Pluto Charon it's between them.this would still make the moon a large satellite. Phobos has a huge crater too,stickley I think it's called, this must cause huge tidal stresses on Phobos so it could break up too?speaking of our moon sadly I missed the lunar eclipse. I was in Sligo in western Ireland at the time but clouds moved in however there's a partial solar over northern Europe on the 11th of August.I'm not sure if it'll be visible from Ireland, the information says northern Scotland, Orkney and Shetland islands. Much depends where they consider northern Scotland as beginning, I'd say Perth but they might mean north of Inverness even?

 

I note swift was a Church of Ireland clergyman and once head of St Patrick's cathedral Dublin. One of my great grandfather's was a Church of Ireland church minister and somehow got buried in Arlington cemetery in Virginia. That was many Martian moons ago.

 

Stranger than strangelove now they've found a lake on Mars under the ice!-66c is the water temperature whilst lake Vostok under the Antarctic ice is a tepid -13c..salt stops both lakes from freezing solid.it appears that life forms are to be found in lake Vostok but Antarctica is much milder than Mars plus however Mars like the 7th continent is you can still breath there and it benefits from the earths magnetic field.
