@neiltyson What's the brightest star we can see from earth? North Star? (I know you said North Star isn't the brightest) -
@iamramsey@neiltyson The sun ? -
@GuillaumeCr@neiltyson Aside from the sun :) I meant nighttime stars.

@neiltyson Hey Neil. I tried to do this for myself, but I end up with a factor ~5.7. Am I doing anything wrong? http://goo.gl/5f5GlThanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson Is that considered a large amount overall?Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson Also, any time saying "bigger" should be considered wrong. Is that radius, area, volume, or mass that's 300x bigger?Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson The surface area that Jupiter presents to the sun is 859 times that of Mercury. pi r^2. Where does 300 figure come from?Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson In Frink, correct calc is: (pi jupiterradius^2/jupiterdist^2) / (pi mercuryradius^2/mercurydist^2) http://futureboy.us/frinkdocs/ - End of conversation

@neiltyson This is incorrect. Jupiter receives 4.75 times as much energy. Show your calculations.Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson So catching more light means you catch more energy?Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson Jup receives 50% more E from sun than Merc? E received is function of volume of space you take up, not distance from E source?Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson Hmm, I get (R_j/R_m) ~30. So I'd expect the energy to go like (30^2)*(0.5%) = 4.5 times the energy. Did I miss something? -
@johnmarcampbell You're right. Factor is 4.75 times. Neil is wrong. See http://futureboy.us/blog/sunsetequator.html … -
@aeliasen Thanks. Not a big deal, just wanted to make sure I understood what was going on. -
@johnmarcampbell Now just need to contact 1 million more people to help them unlearn the incorrect fact... :)

@FKinHOU Neil's math is wrong. Jupiter receives about 4.75 times as much energy as Mercury does. see http://futureboy.us/blog/sunsetequator.html …Thanks. Twitter will use this to make your timeline better. UndoUndo
