| The Saturn symbol appears|
on baby Hotaru's forehead
in the anime
The planetary symbol of Sailor Senshi was usually the astronomical symbol of their planet. It could appear on their forehead when they awakened to their true destiny as Sailor Senshi, or when they performed feats of great power. It was also used as a motif on their magical items, such as their transformation wands.
Sailor Moon's planetary symbol, the golden crescent moon, was worn by all members of the Moon matriarchy and the Moon cats in both their human and feline forms. Sailor V, as the decoy Moon Princess, also used the crescent-moon mark.
Nemesis' planetary symbol might have been the upside-down black crescent moon that all the people from this planet had on their foreheads.
- In the anime, the Inner Senshi's symbols were sometimes stylized slightly to replace the circle in the actual planetary symbol with a heart. In the manga, the symbols on the Star Power Sticks also had the heart, but otherwise the symbols appeared with the standard circle. The circular symbols were also used in the first three seasons of Sailor Moon Crystal, but were replaced by heart-shaped symbols in Sailor Moon Eternal. The heart-shaped symbols were also used in Pretty Guardian Sailor Moon.
- The Sailor Quartet were not shown to use any symbol, although there are symbols for their asteroids.
- There is also more than one symbol available for Pluto; Naoko Takeuchi used the conjoined "PL" symbol for Sailor Pluto, whereas the other symbol, unused in Sailor Moon, is similar to the symbol for Neptune.
- Sailor Uranus used a symbol like a globe with an H speared onto it, which is not the symbol for Uranus in use by NASA.
