Many years ago I came up with symbols for Salacia, a likely dwarf planet, and her moon Actaea. Salacia is a sea goddess often depicted accompanied by seahorses so I created a seahorse-inspired symbol for her where the tail included a lower-case sigma, for Salacia, and then applied the same tail to an alpha for Actaea. (Those symbols are on the left in the picture above.)

A correspondent pointed out that Salacia is actually Roman, not Greek. With some input from him I eventually came up with a version of the symbols that used an s instead. (Those are on the right in the picture above.) Strangely, Actaea is Greek (which is probably what confused me originally) so maybe the a in her symbol is still an alpha? Who knows.
