I suspect the hologram was designed more for illustrative purposes, not for size accuracy. Kinda like this diagram from space.com.
It's also possible that the outer moon of Calpamos is in a wider orbit, like Callisto, and thus didn't make the cut when they designed the hologram.
"wider orbit" I thought of that, I think that makes good sense.
Does anyone know if this is a fact? "Calpamos (117, 925 km), the ringed gas giant that the moon LV-426 revolves around in the Alien series"
I was wrong earlier. I was using the radius of Jupiter and not the diameter. Therefore the largest possible size would be 280,000km or twice Jupiter's diameter of 139,822 km. Which makes good sense, as Jupiter is already almost at the maximum size for a Gas Giant. If the earlier info that e found of LV-426 having a 3,500km diameter it would make perfect sense. It would put LV-223 in the 5,000km+ diameter range.

More to the point, Calpamos is 10x the size of Jupiter?
That moon should be a freaking pinprick if it's only 1,200 km across.
That's actually not possible, it would implode from it's own gravity. Jupiter has a diameter of 139,800km. A planet cannot have a diameter of 1,398,00km. Max from what I was reading is 1.5x - 2x Jupiter's diameter. If you add more mass it implodes.
I think that info earlier with Calpamos being 117,000km is very probable. With LV-426 at 3,550km and LV-223 the size of Ganymede or around 5000-5,500km. Forget the hologram by the way, as there is not enough room for the 3rd planet's wide orbit and the moons are made to look bigger to study them/showcase them better. And the space scene uses various shots to make the moons look bigger than they really appear. The 3rd moon is far in the distance because it has a much wider orbit. I think these are the best solutions and/or explanations.
