Apparent size of planets from moons?

[sunburke]

I've worked this before with a lot of trial and error, and I just want to make sure my method was accurate or if there is any better way to go about it.

Say I was standing on Calypso or Ganymede and wanted to know the apparent size of Jupiter in the sky when compared to viewing the Moon from Earth. How would I go about the math?

first you have to know the distance betwin Calyspo and Jupiter.
than we can talk about it

Our Calypso or the Saturn moon of Calypso?



Calypso = A moon orbiting Saturn
Ganymede = A moon orbiting Jupiter

So I guess that the answer would be very different between those two? or did you mean Callisto and Ganymede?
