So they claim to have finally succeeded in finding Y-type stars.
Now that there's a possible use for it, has the implementation of the Y spectral type been considered?

Finally stars at ambient temperature. I like such spring-summer stars.

Well that's going to be interesting, to do this we're going to need to remap the spectral type representation a bit because we've run out of hexadecimal digits for the "normal" stars sequence.

Of course these things are so cold they are only visible by reflected light and we don't support that for stars either. This would have other applications beyond brown dwarfs, e.g. reflection effects in close binary stars.

There's also the lonely planets issue. Currently, there's no way to place a rogue planet somewhere in Celestia's space (or even a spacecraft). We need more "special" classes in Celestia.

Hey! "WISE" rhymes with "Y"!

Intentional?
