A font which uses ligatures to encode symbols for the major moons.

Astromoony Font

I created a font that uses ligatures to include symbols for the moons. For example, “♂I” will be rendered as a symbol for Phobos, the first moon of Mars.

Symbol Credit

Most of the modern designs above (for dwarf planets and major moons) are based on the public-domain symbol designs by Denis Moskowitz. Note that my glyphs for some objects (namely Europa, Ganymede, Callisto, Kerberos, and Orcus) are substantial deviations from Moskowitz’ designs, though they still keep to the ‘core idea’ of his designs.

Other Fonts

The Catrinity Font by Alexander Lange contains all official unicode astro symbols, as well as a large number of asteroid symbols in its Private-Use-Area. When making the glyphs in the Astromoony Sans font, I designed them to be stylistically similar to the astro symbols from Catrinity.
