In the world of Sailor Moon, celestial bodies hold immense power. It's the planets (and the Moon) that give the heroes their power. That's not unlike astrology, in which different signs have different traits – and different ruling planets – associated with them. In fact, Sailor Moon creator Naoko Takeuchi spent a lot of time thoroughly planning out Sailor Moon's world to account for those ruling planets.

In addition to including favorite foods and blood types associated with her characters in the manga, she also included their birthdays and zodiac signs. Most of the Sailor Scouts have a birthday that lines up with their planet's associated astrological sign. A few Sailor Moon zodiac signs, however, don't quite match up.

Updated December 1st, 2021 by Brittanie Maldonado: Sailor Moon is a beloved and classic anime series that still draws in fans today. Every character has a surprising amount of history and information available for them, making for a richer cast audiences love watching. It also helps that each Sailor Scout generally matches their Zodiac sign quite well. Most of the time.

10 Sailor Mercury Accurately Represents Virgo

Resourceful and analytical, Virgos are the planners of the zodiac. They have a reputation for making lists and keeping their friends organized – whether their friends want them to or not. That's certainly a good way to describe Ami, whose birthday falls on September 10. Not only is she the Sailor Scout who analyzes their opponents to help with battle plans, she's also the friend most concerned with organizing study groups. Ami is the one making sure they all study for their exams while they're saving the world.

9 Sailor Venus Does Libra Justice

Libra is represented by the scales, much like the symbolic Lady Justice herself. It's fitting that Sailor Venus, who is the Sailor Scout of Love and Justice, is a Libra. Born on October 22, she lands at the very end of Libra season. Much like Geminis, Libras are social butterflies. Charming and outgoing, they tend to make friends and dissolve conflicts easily. Those are great qualities for the leader of the Inner Scouts to have. Minako even acts as a mediator in their friend group, calming conflicts between her fellow Scouts in their civilian lives.

8 Sailor Mars Nicely Symbolizes Aries' Energy

Aries tend to enjoy being the center of attention. That might be true of the '90s anime version of Sailor Mars, but not so much the manga. Nevertheless, Rei still possesses other Aries traits to go along with her April 17 birthday.

Besides thriving on attention, Aries also tend to be creative thinkers with incredible drive. That's certainly more in line with Rei, who works as a shrine priestess and uses her visions to aid her friends. She believes in the supernatural more than her teammates, and she's always ready with an out-of-the-box idea.

7 Sailor Jupiter Doesn't Quite Match Sagittarius

With her birthday on December 5, Sailor Jupiter lands right in the middle of Sagittarius season. Those born under the sign tend to be knowledge and truth seekers, always pushing themselves toward lofty goals. Some Sailor Moon zodiac signs don't quite match their character, however, and Makoto isn't quite Sagittarius material.

Interestingly, when astrology was first born, Jupiter was the ruling planet of two signs: Sagittarius and Pisces. Pisces, the romantic and perpetual dreamer, might actually have been a better fit for Makoto. That sign ends up associated with another Sailor Scout, however.

6 Sailor Saturn Encapsulates Capricorn's Dedication

Born on January 6, Hotaru and Sailor Saturn fall under Capricorn. Capricorns are known for their dedication and diligence, as well as their tendency to take initiative. While the audience doesn't spend as much time with Hotaru as the other Sailor Scouts, she certainly seems to fit the bill. Hotaru's extremely dedicated to the people she cares about, even willing to sacrifice herself to save Chibiusa's soul. When Sailor Saturn awakens, she takes initiative immediately, ready to end any conflict herself – which is part of what makes this Sailor Scout so dangerous.

5 Sailor Uranus Expresses Aquarian Rebellion

With her birthdate just a few weeks after Hotaru's, Haruka's birthday falls on January 27, making her an Aquarius. Sailor Uranus doesn't fall under the category of Sailor Scouts who symbolize ancient ruling planets in astrology. That's because Uranus, Neptune, and Pluto weren't known to be planetary objects to ancient astronomers. Aquarians tend to be the most unconventional zodiac signs. That's not unlike Sailor Uranus using a sword in battle despite having her magical powers as well. They develop revolutionary ideas and tend to be incredibly independent – like dividing the Sailor Scouts into two camps.

4 Sailor Neptune Is An Accurate Representation Of Pisces

With Sailor Neptune celebrating her birthday on March 6, Michiru is the water sign Pisces. It's fitting that Neptune, named after the god of the ocean, and Michiru, with her love for swimming, would fall under this sign.

Pisces are often considered the most spiritual of zodiac signs, open to the possibilities of the unknown. That fits with Michiru's prophetic dreams and ability to feel when danger is coming to the Sailor Scouts. She also shares the creativity of Pisces with her love of music and art.

3 Sailor Pluto Matches Scorpio's Tendency To Keep Secrets

Scorpio season officially begins as October comes to an end. Sailor Pluto's October 29 birthday puts her relatively early in the season. Scorpios tend to be ambitious and intuitive. While Sailor Pluto doesn't seem like the former, her civilian identities certainly are. She often works or studies in various scientific fields when Setsuna lives in Japan. Scorpios also tend to develop lasting relationships, taking the secrets of their friends to the grave. That's what makes her so great for guarding the space-time doorway.

2 Tuxedo Mask Captures Leo's Magnanimity

If Tuxedo Mask were a Sailor Scout, he'd be associated with Earth. There isn't a zodiac symbol ruled by Earth, but there is one ruled by its sun: Leo. With his birthday on August 3, Tuxedo Mask is definitely a Leo. Leos are often the life of the party with their charming personalities. That may be why many characters develop a crush on Mamoru in the series as a whole. Leos are also generous and strong leaders. While he begins his time in the story more distant toward Usagi, he soon becomes her greatest supporter.

1 Sailor Moon & Chibi Moon Represent Cancer's Thoughtfulness

Sailor Moon and Sailor Chibi Moon are unique among their teammates. Chibiusa is Usagi's daughter from the future and they share a June 30 birthday, making them both Cancers – the astrological sign ruled by the Moon. Cancers, like the crab that symbolizes them, can produce a hard exterior when they feel threatened, but they have a soft center. Usagi and Chibiusa feel things deeply and are the best friends anyone can ask for. Loyal and willing to provide love and forgiveness first, it's no wonder their friends look to them to lead.
