From: Chandra Wickramasinghe Sent: 2015-01-25 14:13 To: William (Bill) E. Smith Subject: Re: Simple orbit mathematics Dear Bill The pressure exerted by sunlight (radiation pressure force) would not be significant for the comet, but only act on the dust escaping from the surface. That is why the dust tails curve away from the gas tails...
in BLOG 2015-1-25 : 67P’s perihelion is further out from earth (between earth and mars) I was wondering what the “pressure” really was on the comet?
Dear Chandra: In my student days I would not have had to ask you this question. But I have not enough time to relearn orbit mathematics even though I have “scanned” this : http://en.wikipedia.org/wiki/Orbit I am thinking about the force exerted on a orbiting comet as it approaches its perihelion. I assume the force is maximum...
