Re: Rosetta comet landing due today
Something has always puzzled me, with comets. They're essentially asteroids that get close to the sun, close enough for some material to melt and leave a streaming 'tail' that makes it very visible. If this is the case, each pass must make it lose mass, you'd think after seeing some comet tails that are very long and presumably containing lots of material that after a few passes there wouldn't be any mass left?
