Thanks for that news John,

As a starting point, here's a quickly thrown together *fictional* SSC for it (modified from Larissa's orbital definitions):

cc_neptune_newmoon.zip

(Extract to extras.)
- I've modified only the reported information (radius, period, semi-major-axis, and made a wild guess for Albedo). All other values remain as for Larissa (for now).

This can be updated as more accurate information becomes available.

A well done by CC. And thanks to John for the news.

Thanks for the addon, but it is supposed to be 9.656 in radius, not 19. NASA told this newly found moon is 12 miles across. That means it is measured in diameter, not radius. 12 miles is 19.312 km.

19.312/2= 9.656

Well spotted (I misread it as radius).
I would suggest however that not enough is known at this stage to be able to express it's radius with four significant digits, so I would just plonk for a radius of either 9 or 10, or maybe 9.5 (whichever you prefer) at this stage.

It was discovered on July 15, 2013 by Hubble Telescope. It is weird knowing the fact that we are still don't know fully about our own solar system. I don't know what was the reason, why scientists were not able to discover it previously.
