[[caption-width-right:250: [[Manga/AxisPowersHetalia Draw an oblate spheroid]], that's the Earth. [[note]]From left to right- top row: Mercury, Venus, Earth, Mars. Bottom row: Jupiter, Saturn, Uranus, Neptune.[[/note]]]]
A 5-10 paneled [[{{Webcomics}} webcomic]] about [[CastOfPersonifications personifications of the Solar System and other celestial bodies]], following the adventures of [[AmbiguousGender Earth]] and their [[LoadsAndLoadsOfCharacters celestial friends]].

The art style could be described in a way as Creator/HidekazHimaruya [[JustForFun/XMeetsY meets]] Creator/{{CLAMP}}. It incorporates elements and inspirations from both (with ''Webcomic/AxisPowersHetalia'' apparently a major influence) while at the same time retaining something distinctive from either two.

Main comics can be found [[https://planetarymoewebcomic.wordpress.com/ HERE ]].

----
!!This series provides examples of:
* ABoyAndHisX: Mars and his mute alien buddy, Marty.
* ActionGirl:
** Bellatrix.
** Venus might also qualify.
* AllThereInTheManual: Other characters aside from the Solar System, still has no character design and only mentioned on character summaries.
** Others characters are drawn, but haven't appeared on the comic yet.
* AloofBigBrother: VY Canis Majoris. He's aloof and [[WorldOfPun he's big]]; in fact, he's one of the largest stars in existence, which is why his little brothers admire him.
* AmbiguousGender: Earth is too androgynous for the other characters to tell, with some assuming Earth to be male and some female. Most simply don't think of it much at all.
* AmbiguouslyBrown: Black Hole's skin is darker than most of the other characters but his exact ethnicity is impossible to pin down and his hair is apparently naturally white. Earth and Mercury gain darker skin colors after their redesign.
* AnimalEaredHeadband: Many of the stars in constellations wear headgear themed after their constellations.
* {{Animesque}}: The characters have eastern-influenced designs, and the comics themselves are done in the style of 4-koma webcomics. After the 2017 revamp, the style switched over to faux-screenshot sets as if the comic had its own anime.
* AnyoneCanDie: Everyone has more or less come to terms with the fact that they can all die in some manner eventually, despite being incredibly long-lived beings.
* ArtEvolution: [[https://twitter.com/Rosel__d/status/942615869623955456 Here's]] a comparison of the cast's 2011 looks to their 2017 redesigns.
* ArtisticAge:
** The planets look barely out of their teens but are [[ReallySevenHundredYearsOld actually older than they look]].
** The stars on the other hand tend to look ''at least'' in their twenties for the most part.
* ArtShift:
** Usually done during [[DreamSequence daydreams]] and when they are frightened or shocked.
** In one strip, Saturn's style seemed to turn 3D whenever he was photographed.
* BaldOfAwesome: One of Saturn's moons, Enceladus is both bald and very tough. He [[BerserkButton doesn't take kindly to those who call him 'bald']], though.
* BatmanCanBreatheInSpace: They are [[MoePersonification personifications of celestial objects]] so it's no big deal.
* BelligerentSexualTension: [[CasanovaWannabe Sun]] and [[{{Tsundere}} Venus]]; Sun is constantly trying to woo her and she steadfastly rejects him, though it's implied that she's more interested in him than she admits to herself.
* BewareTheNiceOnes:
** The Milky Way. She usually comes across as gentle if not motherly at times. But screw with her and expect a good chance of ''dying.''
** Earth is also mentioned as having a dark side beneath their usually ditzy personality, which normally manifests itself in wars, pollution and so on.
* BigGuyLittleGuy: Jupiter and Mercury, usually.
* BigFancyHouse: Jupiter has a very big house since he's the biggest planet... but it's enveloped in a ''perpetual storm''.
* BishieSparkle: Sun's default mode.
** Also [[TheDandy Sirius]] [[PrettyBoy A]].
** [[EverythingsBetterWithSparkles And other stars]].
* BlandNameProduct:
** [[UsefulNotes/PlayStation2 Planet Station 2]]
** Coltress
** There's also the spacesuit Earth tries on bearing more than a passing resemblance to [[WesternAnimation/ToyStory a certain space ranger toy]].
* BlindingBangs: Charon.
* BlondeBrunetteRedhead: Venus, Earth and Mars, respectively.
* BreakingTheFourthWall: Sirius A talks back to the readers.
* BritishStuffiness: Uranus' moons.
* ButtMonkey: Sun and [[PlutoIsExpendable Pluto]].
* CameraFiend: Earth is constantly trying to take pictures of everyone, usually pissing them off in the process.
* CasanovaWannabe: Sun thinks he's far more irresistible than he actually is.
* CastOfPersonifications: The comic is about the personifications of various celestial bodies interacting with each other. They have the appearance of attractive young humans, and have pseudonyms that they use when visiting Earth. [[MindScrew Yes, even Earth themself.]]
* ChainmailBikini: When Milky Way is ''really'' pissed off, her GorgeousPeriodDress transforms into a rather revealing and form-fitting piece of armor similar to a Valkyrie.
* ChristmasSpecial
* {{Cloudcuckoolander}}: Earth could be this... and [[OneOfTheKids Mars]].
* ColorCodedCharacters:
** Sun: [[color:lightyellow:Light Yellow]]
** Mercury: [[color:darkbrown:Dark Brown]]
** Venus: [[color:yellow:Yellow]]
** Earth: [[color:green:Green]]
** Mars: [[color:red:Red]]

** Saturn: [[color:grey:Silver]]
** Uranus: [[color:teal:Blue-Green]]

* DreamSequence:
** Sun has one about Venus, [[UnsettlingGenderReveal which ended with the (fake) revelation that Venus is actually a dude]]. After that, Sun wakes up in a panic and has to confirm to himself it wasn't true.
** Sun has a more serious one later, about what will happen when he becomes a red giant: he will kill at least two of his closest friends, Venus and Mercury, and will possibly kill Earth. Unnervingly, the comic leaves it open to the interpretation that he was DreamingOfThingsToCome- ''[[OrWasItADream or that he wasn't dreaming at all.]]''
* DudeLooksLikeAlady: Mercury, Saturn and Neptune are all very pretty men. Earth could fit in there too, [[AmbiguousGender if we know what their gender actually was]].
* EitherOrTitle: ''Planetary Moe, or: Solar System and Friends''. The revamp works it in as a case of ShortTitleLongElaborateSubtitle.
* EverythingsBetterWithSparkles, [[EverythingsBetterWithRainbows Rainbows]] and stars.
* {{Expy}}: One of the personifications living with Earth bears a passing resemblance to [[Webcomic/AxisPowersHetalia Poland]]. Also, Jupiter's design seems to have taken more than a few hints from Russia's.
* ExtremeDoormat: Sirius B lets his brother Sirius A walk all over him.
* FieryRedhead: Antares and Arcturus are mentioned to be two of those.
* FunTShirt: More like Fun Aprons.

* GeniusLoci: Earth technically counts, seeing as they can visit ''themself'' while still remaining sapient.
* GorgeousPeriodDress: The Milky Way is usually seen wearing Victorian-style dresses. [[BewareTheNiceOnes Usually.]]
* HairDecorations: Most of the female characters, except for Venus. Neptune provides the male example.
* HairTriggerTemper: Io, being the most volcanically-active celestial body known in the solar system.
* HalloweenCosplay

** The Galilean moons have this theme as well.
* MoeAnthropomorphism

** One of Earth's cameras is called "[[https://en.m.wikipedia.org/wiki/Viking_program Viking]]".

** One strip has Earth buy a NASA t-shirt like a [[http://knowyourmeme.com/memes/24899 certain other personification of Earth]]... only for Luna to stick on some of their ''other'' space programs' logos as revenge for the many flags Earth puts on her. Ironically, Luna never wore the shirt herself despite looking more like the Earth-chan they were parodying than Earth did.
* ShowWithinAShow: ''The Sirius Show'', hosted by Sirius A.
* ShrinkingViolet: Pluto.
* SinisterShades: Sagittarius A* sports one.
** The neutron stars as well.

* VagueAge: The characters look vaguely young adult-ish, despite the vast differences in planetary age.

* WorldOfPun
* {{Yandere}}: Some of the giant stars have...''very'' unstable tempers.
* YouGottaHaveBlueHair:
