Mars' moons
« on: May 09, 2011, 02:53:46 AM »
Could a large meteorite have hit Mars at one point in the past? The remnants of that event would explain how its moons formed. It could also explain what happened to its atmosphere. Could a collision with an object eject some of Mars' atmosphere?

Origin of Phobos
Origin of Deimos

It seems like one hypothesis is that the moons were captured from the asteroid belt. But another one is, as you suggest, that they were formed by an object colliding with Mars.

As Bla said, most likely they came from the asteroid belt via Jupiter swinging them at Mars. Your suggestion does make a connection of the formation of our Moon, though.

That's a big bounce, because the object that would of run into the earth would of been annihilated, unless you meant just saying that the similarities are intriguing.  the only way to know that for sure would be to take samples of Phobos and Deimos and then compare it to martian soil
