Yokutanga yakawana nyika kunze kweSolar System yedu yaive Gliese 876b uye inofungidzirwa kuti inogona kunge yakazvarwa pasi pekutenderera kweZuva kana, neimwe nzira, yakave chikamu chenyika dzatinoziva nhasi uye dzinodzidziswa kuchikoro. Hazvigone kutaurwa nechokwadi kuti Gliese 876b ndeye exoplanet, uye nechikonzero ichi, zvidzidzo zvakaitwa izvo zvino zvinoratidza mukana wekuti yakakwezvwa neZuva.
Unogona kufarira kuverenga: ZVINHU 5 ZVINHU ZVAUNOFANIRA KUZIVA PAMUSORO PAMUSORO PEKUPUPUKUKA KWENYEREDZI KWA2022.
Gliese 876b inozivikanwa seDiscovered Planet iri kure kure kupfuura Pluto uye mabviro ayo haasati azivikanwa. Pakati pefungidziro ndeyekuti inogona kunge yakatanga semhedzisiro ye nyeredzi iyo yaitenderera pedyo neimwe nyeredzi yakafanana neZuva, iro rinonzi Gliese 876 uye zvinofungidzirwa kuti Gliese 876b ipuraneti rinoritenderera. Kuti udzidze zvakawanda nezvemapuraneti akasiyana ari musolar system yedu, unogona kuverenga nezvazvo Mapuraneti mangani ari mugadziriro yezuva?.
Asi, kunyange zvazvo pasi Gliese 876b iri kutenderera mune imwe orbit, nyanzvi dzenyeredzi dzinoti kunyange zvakadaro zvinogoneka kuti pasi rino rave chikamu cheSolar System yedu, zvakangoita zvehumbimbindoga uye pamwe zvakaitika pane imwe nguva iyo Gliese 876 System yakapfuura pedyo neZuva uye neayo. simba regiravhiti rine simba rakwezva pasi Gliese 876b richiita kuti ritenderere kwechinguva.
Zvinofungidzirwa kuti gare gare pasi rino rinogona kudzoka kuita kana kuumba chikamu cheavo vanotenderera zuva.Asi zvidzidzo zvinoenderera mberi nekuti hazvizivikanwe nechokwadi kana Planet Yakawanikwa yekutanga iri exoplanet (nyika iri kunze kwekutenderera kweSolar System) kana kuti chikamu cheiyi sisitimu, kunyangwe pane imwe nguva yakadzingwa kubva mairi, ikozvino ichiita chikamu chekutenderera kwenyeredzi Gliese 876.
Pedyo Exoplanet KuPasi

Pamberi pe maziso e teresikopu uye zvikwata zvekutsvagisa, ingave yemunhu kana marobhoti, ipasi idzva. Uye nokuda kwechikonzero ichi zvidzidzo uye masvomhu zvakakosha kuti zvitsigire kana chiri chinhu chitsva chiri muchadenga, maererano nenguva yachakabva uye kwete maererano nenguva yachakawanikwa.
Kune chikamu chayo, pasi Gliese 876b, kusvika zvino ine kurapwa kwesainzi se exoplanet inotenderera kutenderera nyeredzi Gliese 876 uye nekudaro yakaiswa pasi pezita rimwe chete, asi hazvirambidzwe kuti pasi rino raigona kunge rakave nemavambo pasi pehurongwa hwedu hwenyeredzi, ndiko kuti Zuva uye nechikonzero ichocho. vamwe vane ruzivo vanosarudza kusatorwa senhando pakuritumidza se exoplanet. Kune avo vanoda kuzama zvakadzama munyaya yemapuraneti ane matombo, tinokukokai kuti mudzidze zvakawanda nezvazvo matombo mapuraneti.
Gliese 876b Yekutanga Planet Yakawanikwa
Un boka renyanzvi dzenyeredzi Nyika dzepasi rose dzakasarudza kushandisa Hubble Space Telescope nechinangwa chekuti nemudziyo uyu vakwanise kuwana zviyero zvehuremu hwepasi Gliese 876b, inova iri padyo, kunze kwesolar system yedu. Hubble akabvisa zvine mutsindo achiratidza kuti ipuraneti rakakura zvakapetwa ka1,89 kusvika ku2,4 pane saneti Jupiter, hombe munyika. saizi yesolar system.
Zvimwe unoda kuziva nezve: CONSTELLATIONS: CHAKAVANZIKA CHAKAVANZIKA CHENYEREDZI MUNZIRA YEDU YEMAKA.
Vamwe vanotofunga kuti huremu hwakakura kupfuura izvozvo, kubva pa1,9 kusvika ku100 saizi yeJupiter. Kufungidzira kwapfuura, uko kune zvimwe kusava nechokwadi, isa iyo huzhinji hwenyika mune zvakawanda zvakapamhama: pakati pe1,9 uye 100 nguva yeJupiter, zvisinei iyi ndiyo yechipiri exoplanet iyo vhoriyamu yakaongororwa kuti ione ukuru hwayo. Kana iwe uchida kuziva zvakawanda nezve exoplanets kazhinji, unogona kuverenga nezvazvo mapuraneti anogona kugara.
Pamusoro peizvi, zvakare zvave zvichiita kuziva kutenderera kwenyeredzi Gliese 876, iyo yakatumidzwa zita remadunhurirwa. red dwarf star uye kuti kuva nekukura kudiki kwakadaro (inenge 32% yehukuru hwechiedza cheZuva), kunyangwe zvakadaro zvinotevera kuti mapuraneti matatu anoitenderera, pakati payo pane Gliese 3b, inova ndiyo yatiri kunyora nezvayo muChinyorwa chino.
A Little Space History
Anenge makumi maviri emakore apfuura (19 makore, kuve chaiwo) maviri exoplanet zvikwata Vakawana kuvepo kwepasi riri kunze kwezuva, asi iro rinotenderera kune yambotaurwa nyeredzi Gliese 876. Nechikonzero ichi nyika yakanzi Gliese 876b, nekuda kweongororo iyi muvhimi ane mukurumbira we exoplanet aivepo achitungamira rimwe remapoka, zita rake ndiGeoffrey Marcy. Kuwanikwa uku kwaive chikamu chenguva inonakidza yezvenyeredzi, yakafanana nebasa rakatungamira kuongororo yeMars, inozivikanwa se the red planet Hercolubus.
Kuburikidza nechidzidzo ichi ndipo pakawanikwa ruzivo kuti pasi Gliese 876b inotora mazuva anosvika makumi matanhatu nerimwe tenderera zvachose kutenderedza orbit. Nekudaro, mushure meizvozvo, kumwe kutsvagisa kwakasimbisa kuti pasi rino rinogona kutora mazuva anosvika makumi matatu kuti ritenderere zvachose dzvuku.
zuva kukwezva
Parizvino, chokwadi chekuti pane imwe nguva Zuva rakateya mukati maro star system kune ino yekutanga Discovered Planet uye kana chiri chokwadi, izvi zvingadai zvakaitika nekuti nyeredzi hadzirambe dzakamira panzvimbo imwe chete, kureva kuti, hadzina kumira, asi kuti dzichengetedze orbit nekutenderera pakati pePasi. girazi uye pane dzimwe dzenzendo idzodzo vangave vakasangana. Kune avo vanoshamisika nezve dynamics ye solar system, zvinonakidza kuverenga nezvazvo solar system uye maitiro ayo enzvimbo.
Kubva pakutsvagisa kwakaitwa nechikwata chakatungamira muvhimi we exoplanet muna 1998, Geoffrey Marcy. Jupita, sezvatatotsanangura.
Zvekare Solar System Ine 9 Mapuraneti
Makore gumi nerimwe apfuura, mabhuku akanangana nezvikoro zvepuraimari akagadziridza zvirimo zvinoenderana nedzidziso yemapuraneti, nekuti International Astronomical Union (NDINOTORA, nokuda kwechidimbu chayo muChirungu) shandura kubva pamapfumbamwe kusvika kusere nhamba yemapuraneti ari muSolar System, kubvisa Pluto uye kuderedza chikamu chayo se "dwarf planet".
Nekudaro, 2016 yapfuura, tsvagiridzo yakatanga iyo inoongorora pasi repfumbamwe zvakare muSolar System uye inogona kuwanikwa kure kubva kunzvimbo uko. Pluto inoita orbit yayo. Ivo havasati vasangana nazvo, saka chiitiko chinodiwa chiri kuitwa kuti vazive uye vaone kuti chii chakabva uye kunyange masayendisiti kubva kuLund University, kuSweden, akagumisa kuti haisi iyo yepfumbamwe pasi, asi exoplanet. .
Izvi zvinoreva kuti nyika inogona kutenderera panguva ino iri pasi pekutenderera kweZuva.Kana zviri kuratidzwa nenyanzvi chiri chokwadi, inogona kunge iri nyika yakarasika uye nekuda kwe simba regiravhiti yehurongwa hwedu hwenyeredzi, yakatorwa neZuva, kunyangwe yakamboumbwa ichitenderedza imwe nyeredzi. Kuti unzwisise zviri nani nhaurirano pamusoro pePluto, zvinokurudzirwa kuverenga Nei Pluto isingaonekwe sepasi.
Iko hakuna chokwadi chekuti yekutanga Planet Yakawanikwa ndiyo chaiyo iyo yepfumbamwe iyo inosanganisa solar system uye muchokwadi chikamu chemukana chakanyanya kuderera, 2% uye kunyange 0,1% kuti ichokwadi chinogoneka. Asi chatinoziva ndechekuti chadenga chedu chiri kusika mitumbi yedenga mukati mayo, kuti zvakakosha kuti uvazive, kudzidza zvakawanda nezvavo uye nezvimwe kana paine mukana wepedyo nePasi.
