Zvichienderana neongororo dzezve cosmos, Neptune ndiyo puraneti yechisere uye yekupedzisira mu solar system yedu. Kusvika nguva pfupi yadarika, nyanzvi dzakawanda dzaishamisika kuti: Neptune ine mwedzi mingani ? Zvakaratidzwa kuti, kusiyana nePasi, Neptune ine anopfuura gumi. Neptune inotenderera Zuva mumakore 164, mazuva 323, uye maawa 21,7, uye zuva paNeptune rinotora maawa 16 nemaminitsi 6.6.
Nzvimbo yacho ndiyo inokurumidza uye saka yakachena kwazvo, sezvo paine mhepo inogara ichivhuvhuta mu solar system (inosvika 1600 km/awa), asi mhepo dzayo, dzakaumbwa nehydrogen, helium , uye methane, hadzina simba zvekuti hadzizove mhepo dzinobva panyika. Kunyange zvakadaro, madutu makuru akagadziriswa ipapo.
Neptune ine mwedzi mingani?
Sisitimu yesatellite yaNeptune yakaoma kunzwisisa, sezvo mwedzi wayo mizhinji ingave iri kunze kwezuva. Izvi zvinoita kuti ive nyaya inonakidza yekudzidza nezve nyeredzi.
Kune rumwe rutivi, vazhinji vanofarira nyeredzi, pamwe chete nesainzi iri kudzidza sainzi iyi, vakashamisika kuti: Neptune ine mwedzi mingani? Zvichienderana nemhedzisiro yakawanikwa, zvakaonekwa kuti nhamba iyi inogona kutsamira pazvinhu zviripo munzvimbo iyoyo. Zvikuru, inogona kutsamira paKuiper Belt, uko zvinhu zvakawanda zvinowanzotenderera, kana kungoti pamhedzisiro yekuroverana pakati pezvinhu zvekudenga, izvo zvinozoburitsa zvidimbu zvine chando zvinozopedzisira zvava comets.
Zvino, kana tikaongorora zvakadzama mwedzi wepasi rino, tinogona kuona kuti izvi ndizvo zvinoitika kumwedzi mukuru weNeptune (Triton). Nhoroondo dzakasiyana-siyana dzekuedza kwesainzi dzinoratidza kuti kutenderera kweseteraiti iyi kunogona kuunza shanduko dzinogona kuchinja hunhu hwemwedzi wega wega pasi rino. Kuti tiongorore nyaya iyi zvakanyanya, zvinobatsira kunzwisisa hunhu hweNeptune.
Kuwanikwa kwepasi Neptune
Mwedzi wekutanga waNeptune wakawanikwa nemusayendisiti William Lassell muna 1846 uye ikozvino unozivikanwa seTriton, mazuva gumi nemanomwe mushure mekunge Neptune yawanikwa. Hapana mumwe mwedzi waNeptune wakawanikwa kusvika muna 1949, apo musayendisiti Gerard Kuiper akawana Nereid. Mwedzi miviri iyi yaNeptune ndiyo chete yakaonekwa kusvika pakasvika Voyager 2 probe muna 1989, apo masateliti matsva matanhatu akaonekwa munzvimbo iri pedyo neNeptune.
Mupfungwa iyi, muna 2013, kwakawanikwa mwedzi wechi14, uri pakati peLarissa neProteus. Wakanga wanzi 'S/2004 N1' kwenguva pfupi uchimirira zita rawo. Kuwanikwa uku kunowedzera pane runyorwa rurefu rwemasatellite echisikigo anotenderera mamwe mapuraneti mu solar system.
Parizvino, mwedzi gumi nemana yakarekodhwa ichitenderera Neptune ; iyi ndeiyi:
Naiad
Ndiwo mwedzi wepedyo kuNeptune, wakaratidzwa muna 1989.
thalasse
Ndiyo yechipiri setiraiti yeNeptune, yakaziviswa muna 1989.
despina
Mwedzi unoyevedza uyu waive mugore ra1989 uye wakanyorwa sewechitatu wepasi rino.
Galatea
Ndiwo mwedzi wechina weNeptune, wakaratidzwa muna 1989.
Larisa
Mwedzi wechishanu weNeptune, akashamiswa naReitsema, Hubbard, Lebofsky naTholen muNeptune kurongeka kwenyeredzi.
Proteus
Mwedzi wechitanhatu waNeptune, wakaratidzwa muna 1989 naSynnott naSmith.
Triton
Tatokurukura nezvemwedzi uyu chaiwo, sezvo uri iwo mukuru pane mimwe mwedzi yeNeptune. Uyezve, nekuda kwehuwandu hwayo hwakawanda hwenitrogen, Triton ndiyo inotonhora kupfuura mimwe mwedzi yeNeptune. Pamusoro payo panoratidza chiedza chinosvika 70%, ichitora zvishoma, ndosaka ichitonhora zvikuru. Kuwedzera kune nitrogen, mwedzi uyu une methane neammonia. Kuti uwane rumwe ruzivo, zvinobatsira kuenzanisa ruzivo urwu nerwemamwe mapuraneti akaita seSaturn.
Mitsetse yakasviba inoratidzwa mune mimwe mifananidzo inoita seinopihwa nemamwe makomo madiki ane aizi yenitrogen yakasanganiswa nemakemikari emuchadenga anodzingwa nemagiza emwedzi weTriton.
Nereida
Ndiyo yechisere setiraiti yeNeptune, yakaratidzwa muna 1949 naGerard Kuiper.
halimede
Neptune ine mwedzi yakasiyana siyana uye Halimede haisi kure kumashure, maererano nerekodhi yenhamba yemasatelliti ane Neptune, iyi yakawanikwa muna 2002 uye ndiyo yechipfumbamwe kusvika parizvino.
Nei?
Zvinoenderana neakaundi iyi yemwedzi ine Neptune, takasvika pachinzvimbo chegumi, iyi pasina mubvunzo inogarwa naSao, satellite yakawanikwa muna 10.
laomedeia
Saizvozvowo, kune Laomedeia. Akawanikwa nenzira imwechete mugore rakawanikwa Sao.
taura zvakanaka
Psámate inomira panhamba 12 uye inowanikwa naSheppard.
neso
Ikozvino yave nguva yaNeso. Izvi pasina mubvunzo zvinotora nhamba ye13 uye yakawanikwa mushure meboka raMateo J. Holman.
S/2004 Nha
Pakupedzisira, tinosvika paS/2004 N 1, yakawanikwa nguva pfupi yapfuura, munguva pfupi yapfuura zvekuti haisati yava nezita. Zvisinei, zvidzidzo zviri kuitwa parizvino, zvichiratidza hukama hwakati nepasi redu uye zvichipa mimwe mhinduro kumubvunzo wekuti Neptune ine mwedzi mingani.
Kuti tinyatsoti chechetere uye tichidzokera kunhoroondo yezvenyeredzi, mugore ra1989, zvakange zvafungwa kuti nyika yedu yenyeredzi yanhasi yaingova nemwedzi gumi nemitatu. Nekudaro, nekufamba kwemakore zvakaonekwa kuti izvi zvaive zvisiri zvechokwadi sezvo mutumbi mutsva wakaonekwa muNeptune.
Ndipo pano, mushure mezvidzidzo zvakawanda, apo S/2004 N 1 yakabuda, kana kuti, yakawanikwa—mwedzi pakutanga waifungidzirwa kuti ndiwo wechi14 pane runyorwa rurefu rwemasatellite anotenderera pasi rino guru. Mifananidzo yakanakisisa yesatellite iyi yakatorwa neHubble Space Telescope pakati pa2004 na2009.
Zvaifungidzirwa kuti S/2004 N 1 haina kuoneka mune chero mufananidzo nekufamba kwenguva, kunyangwe kusvika parizvino hazvizivikanwe kuti chii chakanyatso kutorwa neteresikopu. Nekudaro, izvi hazvina chokwadi kune zvazvino sezvo mushure mekudzidza mwedzi mutsva uyu zvakanyanya, zvakaonekwa kunge mutema. Pamufananidzo wauri kuona kunze, maitiro uye akadzikama orbit yemwedzi mukuru weNeptune, Triton.
Ngatitii Triton yakabatwa muKuiper Belt pave paya, Neptune isati yatanga kuumba mwedzi yakasiyana. Kutenderera kwemwedzi yekare kwakakanganiswa nechiitiko ichi chemuchadenga, zvikaita kuti mimwe mwedzi isashande uye mimwe ikaparadzwa. Kuti udzidze zvakawanda nezvekuumbwa kwe solar system uye hukama hwayo neNeptune, shanyira chinyorwa chino pamusoro pekuumbwa kwe solar system.
S/2004 N 1 saka chikamu cheyakasarudzika sisitimu yemwedzi, sezvo ichienderana nemamwe epedyo masatellite eNeptune nematoni easphalt. Kupararira kwakapa kuti iite radius yemakiromita gumi nematanhatu kusvika makumi maviri, zvichiita kuti uve mwedzi mudiki weNeptune, muna 16. Mamiriro akashata ari mashoma kuti aenderane nemamorekuru aripo munzvimbo iyi, asi aizi yemvura yakawanda mumhepo yekunze, inofungidzirwa kuti kuenderana neS/20 N 2013.
Chekupedzisira, zvakakosha kuratidza kuti Neptune yave imwe yemapuraneti makuru mu solar system yedu, uye kukura kwayo kukuru kunoibvumira kugamuchira mwedzi gumi nemana, zvichipindura mubvunzo unobvunzwa nevanhu vazhinji: Neptune ine mwedzi mingani?
