Lapho ekhuluma Uyini umehluko phakathi kweplanethi nesathelayithi , kubalulekile ukwazi imiqondo yalokhu ngakunye. Yingakho isathelayithi yemvelo iyibhizinisi lasemkhathini elizungeza eduze neplanethi. Ngokuvamile isathelayithi incane futhi ihola iplanethi emzileni wayo uzungeze inkanyezi engumzali wayo.
Endabeni Luna, enesisindo esisondela ku-1/81 wesisindo soMhlaba, singacatshangwa njengohlelo lwamaplanethi amabili azungeza ndawonye (isimiso sezinto ezimbili zamaplanethi). Uma izingqikithi ezimbili zinenqwaba efanayo, kuvamile ukukhuluma ngohlelo lwezakhi ezimbili esikhundleni somzimba oyinhloko nesathelayithi. Ukwahlulela kwendabuko kokubonisa into njengesathelayithi ukuthi i-eksisi enkulu yesistimu eyakhiwe izinto ezimbili ingaphakathi kwento eyinhloko. Indawo evelele kakhulu yendawo yesathelayithi yethulwa njenge-apoapsis.
Ngokuthuthuka, izinyanga zibabaza kumasathelayithi amanye amaplanethi. Ibonisa "iziphuphutheki ezine ze-Jupiter", kodwa ngendlela efanayo, "izinyanga ezine noma ama-satellite e-Jupiter". Ngendlela efanayo, ngokukhulisa, isathelayithi yemvelo noma inyanga ikhonjwa kunoma iyiphi into ephilayo ezungeza umzimba wezinkanyezi, noma kungeyona iplanethi, njengoba cishe kwenzeka njalo satellite i-asteroidal Dactyl ukuhamba eduze kwe-asteroid (243) Ida njll. Sekukonke kunamasathelayithi emvelo angama-168 esistimu yethu enkulu yelanga.
Amasathelayithi ohlelweni sonozungezilanga kanye nawo ukuhlukaniswa
Mayelana nalokhu okungenhla, kubalulekile ukuthi ngaphambi kokubalula ukuthi yini umehluko phakathi kwe-a iplanethi kanye nesathelayithi kubalulekile kuqala ukuchaza nokuhlukaniswa kwamasathelayithi. Yingakho ohlelweni lwelanga amasathelayithi angahlelwa kanje:
1. Amasathelayithi omalusi
Lezi yizo ezigcina indandatho yamaplanethi alandelayo: iSaturn, iJupiter, i-Uranus noma Neptune.
2.Amasathelayithi eTrojani
Lawa amasathelayithi ajwayelekile akhiqizwa lapho iplanethi nesathelayithi ebalulekile kunamanye amaphuzu e-Lagrange L4 kanye ne-L5. izinyanga noma amasathelayithi.
3.Amasathelayithi e-Coorbital
Zenzeka uma zidansa emzileni ofanayo. Ngakho-ke lezi zidumbu zingamaTrojani nama-coorbitals, kodwa ngendlela efanayo amasathelayithi we Saturn U-Janus no-Epimetheus abahlukene ezindaweni zabo ngaphansi kobukhulu bawo futhi esikhundleni sokungqubuzana bashintsha izindawo zabo.
4.Amasathelayithi e-Asteroid
Abanye amaplanethi banamasathelayithi ebazungezile njengo-(243) u-Ida nesathelayithi yakhe i-Dactyl. Ngo-Agasti 10, 2005, kwembulwa kwe-asteroid (87) uSilvia, enamasathelayithi amabili ayizungezayo, iRomulus neRemus. I-Romulus, isathelayithi yokuqala, yavezwa ngoFebhuwari 18, 2001 kusetshenziswa i-WM Keck II cishe isibonakude esingamamitha ayi-10 eMauna Kea.
Iphinde ibe nobubanzi obungu-18 km futhi yayo i-orbit, ibanga elingamakhilomitha angu-1370 ukusuka eSilvia, kuthatha amahora angu-87,6 ukuphelela. I-Remo, isathelayithi yesibili, ijabulela cishe amakhilomitha angu-7 ububanzi futhi ihamba ibanga elingamakhilomitha angu-710, ithatha amahora angu-33 ukwenza kahle umgudu oseduze noSilvia.
Futhi, njengoba wonke amasathelayithi emvelo engokwemvelo elandela umzila wawo ngenxa yamandla adonsela phansi, ukunyakaziswa kwengqikithi eyinhloko ngendlela efanayo kucatshangwa satellite. Lokhu okudidayo kwavumela kwezinye izimo ukwembulwa kwezinkanyezi ze-extrasolar.
Manje… Ayini amaplanethi?
Ngaphambili sikwazile ukukhuluma nawe mayelana nencazelo yamasathelayithi bese ngizobalula umqondo wawo amaplanethi ukuze siqonde kangcono.
Ngokuphathelene nalokhu okungenhla, iplanethi iyindikimba eqinile yezinkanyezi ngaphandle kokukhanya kwayo okuhamba eduze kwenkanyezi, futhi lokho kuwumnyombo wocwaningo lwesayensi yezinkanyezi. Esimisweni sethu sonozungezilanga izinkanyezi iMercury, iSaturn, I-Uranus, iVenus, Earth, Jupiter, Neptune, Mars kanye nePluto yizinto eziphilayo zasemkhathini ezizungeza emizileni yazo eduze nelanga, ngokulandelana ukusuka emfushane kuya endleleni ende yenkanyezi eshiwo.
Ngokufanayo, amaplanethi angama-opaque universes anesisindo esanele ukuze isisindo sawo sigcine ingxenye ye-hydrostatic namandla endawo yawo (amandla adonsela phansi umoya), ngaphandle kokuthi indlela yayo ihlaselwe noma ivinjwe eminye imizimba. Iplanethi enguMhlaba iyindikimba yasemkhathini ezungeza ilanga, ngokungafani nama-exoplanet okukhulunywe ngawo ngenhla azungeza eduze kwezinye izinkanyezi.
Iplanethi Neptune yakhiwe inkaba eqinile ezungezwe igesi, futhi iyona eqhelelene kakhulu nelanga. I-Uranus yakhiwe i-axis yamadwala neqhwa elisongwe nge-helium ne-hydrogen. ISaturn ihlanganiswe ngokuyisisekelo negesi, okuyingqayizivele yayo eyizindandatho. I-Jupiter iyinkanyezi enobukhulu obukhulu kakhulu, futhi i-Mars iseduze kakhulu neplanethi enguMhlaba, okuyindawo ekahle lapho ukuba khona kokuphila kuvame ukwenziwa khona namuhla.
Venus kwakuthiwa kusesekuqaleni, futhi endaweni yokugcina iMercury yiyo ebekwe eduze kakhulu nelanga. Kusukela ku-prehistory, izazi ze-physics, izazi zezinkanyezi kanye nezibalo zinendawo yonke njengento yamasiko. Ngokukhulayo, izambulo zesayensi nobuchwepheshe zingene ngemiphumela yokuhlaziya nokubala, okufinyelelwa njengokutholwa kweplanethi ngayinye eyakha i-Milky Way noma umthala wethu.
Izindatshana Ezihlakaniphile ZeNkathi Ephakathi; ucwaningo oluzuzwe ngesibonakude kusukela ngesikhathi sikaGalileo Galilei; uhambo lwemizimba efana ne-NASA (iyunithi yocwaningo lwasezulwini yaseMelika) eyathumela amasathelayithi aklanyelwe ukuqoqa ulwazi ngomzimba ngamunye wezinkanyezi IMilky Way; yonke into ikhombisa ukuthi, kusukela phakade, amaplanethi ayehlolwa futhi azohlolwa umuntu kuzo zonke izinkathi.
Uyini umehluko phakathi kweplanethi nesathelayithi
Amagama amabili ahlukene kodwa uyini umehluko phakathi kwe-a iplanethi kanye nesathelayithi. Lokho kulula ukukucabanga nokukubona, kodwa akulula kakhulu ukukubonisa. Kunomehluko omkhulu phakathi kwalokhu okubili okuchazwe emigqeni elandelayo.
1. Usayizi
Un iplanethi iwumzimba wezinkanyezi ongenawo usayizi omisiwe. Imvamisa, inkanyezi inkulu kuneyodwa yamasathelayithi ayo, nakuba kukhona amasathelayithi okuthi, uma kuqhathaniswa, makhulu kakhulu kunomhlaba, njengoba kwenzeka ngoMhlaba.
2. Sonta
Esinye isibonelo seplanethi ukuthi izungeza eduze nenkanyezi. Esimweni sethu, kungenzeka ukugomela ukuthi i- Umhlaba Izungeza kanye neLanga. Ngendlela efanayo, kuyavela kuthisisi yakhe ukuthi iyabonakala ngokukhanya elikubonisayo.
Iqiniso liwukuthi, ngokuhlanganyela, iplanethi ibhekwa njengenjalo uma igcwalisa isimo sokuthi inesisindo esanele ukuze amandla adonsela phansi aqokomise amandla omzimba onzima, kanye nokuthi ithatha ukubusa okuyindilinga (ukuthi azikho izinto eziphilayo ubukhulu obuqhathaniswa neyakhe emzileni wayo wamandla adonsela phansi, ngaphandle kwe iziphuphutheki)
Ekugcineni, enye indlela yokwazi ukuthi uyini umehluko phakathi kwe-a iplanethi kanye nesathelayithi, sinquma ukuthi isathelayithi yilokho umzimba lokho akuhlangabezani nazo, kodwa ngesikhathi esifanayo kwehluka ngobunye obulandelayo. Isathelayithi inomzimba oguqubele futhi ukukhanya okuvela enkanyezini kuphela okungenza ibonakale.
Ngendlela efanayo, kuhlukaniswa ukuthi uyini umehluko phakathi kwe-a iplanethi futhi isiphuphutheki, okwesibili ngaphezu kwalokho, sikhangwa amandla adonsela phansi enkanyezi, eduze naso esizungezayo. Kuyathakazelisa ukuthi eminyakeni eyalandela kuye kwatholakala nokuthi isathelayithi ingazungeza ama-asteroid esikhundleni salokho esikubiza ngokuthi. amaplanethi.
