[[caption-width-right:300:From Top to Bottom, L to R: Roma, Edogawa, Fumie, Sayo, Saku, Mihoshi and Hime]]
Saku Ooyagi is a quiet bookworm who's moved from place to place over the years, never getting a chance to stay very long or make friends. Though long ago, he remembers how he was dragged around by Mihoshi Akeno, a girl who he ended up saving after she fell from a tall tree. He returns to his old hometown and, now a first year in high school, is about to be in for the greatest upheaval in his life.

Mihoshi, one year ahead of him, is as passionate about astronomy as she was years ago, and is starting up an Astronomy Club at their high school. When she sees Saku, she sets off running after him and gets him to join, not by choice. The Astronomy Club is brand new, and thus regularly faces opposition from the student council.

This romantic comedy manga received an anime adaptation in the summer of 2009.

!!This work provides examples of:

* AccidentalMisnaming: Kawamura and Minami keep calling Mihoshi "Hoshimi".
* ACupAngst: Hime feels this next to Sayo in the BeachEpisode.
* BeachEpisode: Episode 5
* BerserkButton: Hime doesn't like anyone messing with her hair.
** Or reminding her of her old nickname [[spoiler: Drift]]
* BettyAndVeronica: Mihoshi (wild) and Fumie (proper).
* BigBrotherMentor: Souma. Haruko is the CoolBigSis.
* BigNo: Mihoshi's reaction to [[spoiler: Saku denying ever meeting her]]. And pretty much to anything that prevents her [[SeriousBusiness stargazing]]. Actually, almost every main character in the show does a BigNo at some moment.
* BirdRun: Mihoshi loves it.
* BlandNameProduct: Played straight for the ever popular [[strike: Nikon]]''Nihon'' cameras, averted for the Vixen telescopes.
* BlindWithoutEm: Fumie can't see a thing without her glasses, and keeps talking to random things that are not Saku.
* BloodFromTheMouth: Roma's signature move.
* BromanticFoil: Edogawa.
* CameraFiend: Edogawa, Saku's classmate and sidekick. While he does lend his camera to the club for night sky photography purposes, he also loves snapping pictures of Sayo.
* CasanovaWannabe: Edogawa
* ChickMagnet: Saku. Unlike the average main lead in this type of series, he's set up as good-looking and one of the school's heartthrobs from the very first episode. He doesn't like his status, though.
* CloudCuckooLander: Kawamura and Minami. They think of [[CargoShip constellations as teen idols]], and are ...eccentric overall.
* ClubPresident: Roma. Though the official club leader, his tendency to cough up blood at random intervals doesn't do much for recruiting. After Roma graduates, Mihoshi takes up the reign of president.
* CustomUniform: Hime is the only one who wears a yellow sweater with her school uniform.
* CutenessProximity: Kawamura and Minami have this reaction to ''constellations''. "Perseus-sama ''moe''!"
* DatePeepers: [[spoiler: It wasn't actually a date, after all]]
* [[DefrostingIceQueen Defrosting Ice....King]]: Saku
* DescriptionCut: Episode 2. Roma feels a great night for stargazing is coming up. [[spoiler: It isn't, of course.]]
* DotingParent: Saku's mom.
* DropInCharacter: Edogawa is not technically a member of the Astronomy Club. But he hangs around with them so much that he may as well be.
* EvolvingCredits: It's a small difference, but the clothing of everyone changes in the ED animation partway through.
** There are four different variants representing each of the seasons, starting at spring and ending at winter. The constellations shown also change accordingly.
* {{Fangirl}}: Mihoshi's love of Astronomy and stargazing is cranked UpToEleven.
* {{Foreshadowing}}: Mihoshi's reaction to Saku's mom giving regards to her parents.
* GenkiGirl: Mihoshi, who's constantly in hyper mode. Especially when it involves astronomy or Saku.
** And Saku's mom. Genki {{Housewife}}?
* TheGlomp: Again, Mihoshi. Her favorite thing to do to Saku.
** Continuously. In public. No wonder everyone thinks they are an item.
* GreenEyedMonster: Saku [[spoiler: once Souma-sensei arrives and takes some of Mihoshi's attention from him]].
* HippieTeacher: Souma.
* HotLibrarian: Fumie.
* HotSpringsEpisode: The final episode. Complete with implied SkinshipGrope and {{Modesty Towel}}s.
* HugeGuyTinyGirl : Saku next to Mihoshi.
* [[IllGirl Ill Guy]]: Roma, often creepily, PlayedForLaughs.
* ImagineSpot: Mihoshi has them with regularity.
* InnocentInnuendo: Mihoshi's conversation about stargazing with Saku sounds like something else entirely to his classmates when she walks in unannounced.
* {{Kuudere}}: Fumie.
* LensFlare: It's a show about lights in the sky, after all.
* LikeBrotherAndSister: Mihoshi and [[spoiler: Souma]].
* LoveTriangle ([[TriangRelations Type 3]]): Hime is in love with Saku and is afraid that Mihoshi might get him, although Mihoshi's love for Saku seems to be entirely platonic. Saku doesn't seem to be interested in either girl ([[FirstGirlWins yet?]]).
** LoveDodecahedron once Fumie joins. And Saku does seem slightly interested in her.
* LoveYouAndEverybody: Done by Mihoshi, with just enough of a DramaticPause to throw Saku and everybody else for a loop.
* ManicPixieDreamGirl: Mihoshi
** Oumi acts as a milder version for Roma.
* MasterOfTheMixedMessage: Mihoshi obviously likes Saku... but what does Saku mean to her exactly?.
* {{Meganekko}}: Fumie, [[{{Megane}} Saku]] and lots of secondary characters wear glasses. AuthorAppeal, maybe?
* MundaneMadeAwesome:
** Edogawa explaining how to take photos of the night sky in Episode 4... with BattleAura and a ShoutOut to ''FistOfTheNorthStar''
** Episode 6 makes a thrilling psychological battle out of the question who is going to press the "stop" button in a crowded bus.
** Episode 7 has Saku doing [[{{Facepalm}} headdesks]] while ''Music/AlsoSprachZarathustra'' blares and the solar system has gone mad in the background ...because he agreed to [[spoiler: help Fumie on her club activities instead of helping his own club]].
** Episode 11 has the clubs [[spoiler: tried to help Hime and Mihoshi to find their way in a blizzard after they have gone missing, by firing their [[WaveMotionGun]] (or rather, a camera flashlight flashing through a telescope) in the night sky.]] What is more awesome is that it apparently can really be done with a large enough telescope, complete with the firing SFX.
* MyLifeFlashedBeforeMyEyes: [[spoiler: Hime before being rescued by Mihoshi.]]
* NerdGlasses: Roma and Minami.
* NoGuyWantsToBeChased: From the mouth of Mihoshi.
* NoSenseOfPersonalSpace: Mihoshi doesn't believe in "personal space". Particularly Saku's.
* NotWhatItLooksLike:
** Saku keeps repeating this because of Mihoshi's knack for InnocentInnuendo, but a textbook example of this trope happens in Episode 7.
** Fumie recalls an old incident where Souma-sensei was mistaken for a predator while playing tag with Sayo and Mihoshi.
* OlderThanSheLooks: Mihoshi and Maibara from Oumi's Club.
* PosthumousCharacter: [[spoiler: Mihoshi's dad.]]
* SceneryPorn: Since stargazing is the club's focus, lovely shots of the night sky are quite the sight.
* SchoolFestival: The highlight of the show ends up being the club's handmade planetarium, or "Plane-tan". Previously known as [[GratuitousEnglish Star Shining Astro Max Star Ship]].
* SenpaiKouhai: Mihoshi's junior and Saku's freshman status comes up often, if only because Mihoshi keeps invading Saku's class daily.
* SenseiChan: Sakai-chan, the club advisor of the Takami All-girl School.
* SeriousBusiness: All the clubs in the show treat their subjects as a Big Deal. Mihoshi and Roma specially.
* ShesNotMyGirlFriend: Saku is ''not'' Akeno's boy.
* ShoutOut:
** Before meeting her again, Saku imagines an older Mihoshi as [[Anime/{{Doraemon}} Takeshi's sister]].
** ''Manga/FistOfTheNorthStar'' and ''Manga/SaintSeiya'' come up, of course.
** The Antares star evokes its train namesake from ''Manga/GalaxyExpress999''
** Could a series about stargazing avoid mentioning [[{{Tanabata}} Orihime and Hikoboshi]]?
** Edogawa is seen performing a [[Manga/DragonBall Kame-kame-ha]] in the opening.
*** Mihoshi can enter Super Saiyajin mode.
** You can see a life-size [[Manga/{{Gintama}} Elizabeth]] plush among the things Mihoshi bought during the SchoolFestival.
** A double-camera set-up in an equatorial mount reminds Edogawa of [[Manga/BladeOfTheImmortal Kuroi Sabato]].
* ShownTheirWork: The astronomy trivia is surprisingly well researched. [[JustifiedTrope Justified]] because the author is also interested in astronomy and (especially) stargazing.
* SpoilerOpening: Hime isn't introduced until the second episode but she's shown as part of the main cast in the opening.
* StudentCouncilPresident: Fumie.
* TeamMom: Sayo.

* {{Tsundere}}: Rare male example: Saku.
-->'''Souma:''' So, do you... like...\\
