Sezvatakaona muzvinyorwa zvakapfuura, yedu Solar system inoumbwa nemapuraneti masere uye iyo planetoid Pluto izvo zvakamira kutariswa seimwezve nekuda kwehukuru hwayo. Isu tatoongorora zvakadzama Mercury, Venus, Marte, Jupita y Saturn, saka tinogona kutaura nezvazvo nyika Uranus. Inozivikanwa seyakajairwa dhi yebhuruu uye mune ino posvo iwe unogona kudzidza zvese nezvazvo.
Iwe unoda kuziva zvakawanda nezve nyika Uranus? Verenga pamusoro kuti uwane zvese zvakavanzika.
Hunhu hwaUranus
Inotarisirwa senyika yechinomwe mune yedu yezuva zvinoenderana nekuswedera kwezuva. Iyo yepedyo ndeyeMercury, nepo iyo yekupedzisira iri Neptune. Uyezve, isu tinogona kuona izvo, zvemapuraneti mahombe muhukuru (anonzi magasi mahofori), Uranus anove wechitatu.
Iyo ine dhayamita ye51.118 km uye iri chinhambwe chakapetwa kakapetwa makumi maviri pane icho cheplanet yedu zvine chekuita neZuva.Zita rayo rakapihwa kukudza mwari wechiGreek anonzi Uranus. Kusiyana nemamwe mapuraneti ane matombo kana mapuraneti ane mhirizhonga muchimiro, Uranus ine yakaenzana yunifomu uye yakapusa pamusoro. Ruvara rwebhuruu rwegirinhi harusi kuratidzwa kwekuda kwezuva rezuva. Icho chinoumbwa nemagasi chinoita kuti ive neicho ruvara.
Kugona kuiona iri pasi, denga rehusiku rinofanira kunge rakasviba, nemwedzi muchikamu chitsva (Ona izvo zvinoitika zvemwedzi). Kana aya mamiriro akasangana, nema binoculars tinogona kuwana zviri nyore kuti greenish yebhuruu dot.
Musayendisiti akawana ino yaive William Herschel uye akazviita musi waKurume 13, 1781. Panguva ino, vanhu vazhinji vaiyedza kuziva zvakawanda nezvedenga redu uye kuti vaone zviri muchadenga. Kuti awane Uranus, Herschel akashandisa teresikopu yaakazvivakira. Paakanongedza iro rebhuruu-girini dhiza mudenga, akataura kuti yaive comet. Asi mushure mekuyedza, zvaizivikanwa kuti yaive nyika.
Iyo inoverengerwa nhamba yechitanhatu mune rondedzero yemapuraneti muSolar System mushure meJupiter. Kutenderera kwayo kwakakura uye zvinotora makore makumi masere nemasere kuti ifambe kupfuura zvaizoitika pasi pano. Ndokunge, nepo nyika yedu yakatenderedza Zuva makumi masere nemasere, Uranus akaita imwechete chete.
Kuumbwa
Iyo inenge yakapetwa kana kukura kwevhu redu uye kuwanda kwayo inongova 1,29 gramu pa cubic centimeter. Mukuumbwa kwayo kwemukati tinowana dombo nechando zvigadzirwa zvemhando dzakasiyana. Iyo dombo repakati rakanyanyisa kuwanda uye magasi ayo anonyanya kuwanda mumhepo yayo ihydrogen uye helium. Aya magesi maviri ari chikamu chegumi neshanu muzana yeplanete yakawanda.
Ichi chikonzero nei ichinzi gasi hofori. Iko kutenderera kweayo axis yekutenderera ingangoita makumi mapfumbamwe madhigirii zvine chekuita nekutenderera kwayo. Isu tinorangarira kuti yedu yepasi ndeye 90 degrees. Uranus zvakare ane mhete yakaita saSaturn, kunyangwe isiri saizi yakafanana. Kurereka kweiyo axis kunokanganisawo zvindori nema satellites avo.
Nekuda kwekutenderera kwakadaro kweiyo axis, Uranus inongova nemwaka miviri yegore. Kwemakore makumi mana nemaviri zuva rinovhenekera danda rimwe repasi uye kune rimwezve 42 rimwe danda. Kuve uri kure kwazvo neSuva, tembiricha yayo yepakati yakatenderedza -42 madhigirii.
Iyo ine ringi system isina chekuita neyaSaturn uye zvakare ine yakasviba matema (Ona Chii chinonzi rima nyaya?). Semasainzi, zvakawanda zvakakosha zvakawanikwa zvinoitika netsaona uye apo zvichitsvaga zvakanakisa, zvakapesana. Aya mhete akawanikwa muna 1985 apo iyo Voyager 2 space probe yanga ichitsvaga kusvika kune nyika Neptune. Ndipo ipapo apo, nekufamba kwake, aigona kuona mhete dzaUranus.
Neruzivo rwechizvino-zvino uye rwakagadzirwa, zvave zvichikwanisika kuziva kuti imwe yemaringi ayo bhuruu uye imwe yacho yakatsvuka.
Uranus chimiro
Chinhu chakajairika mupuraneti ine mhete ndeyekuti iwo akatsvuka. Nekudaro, zvine rombo rakanaka kuwana mhete dzebhuruu. Mumamiriro ayo uye mukati Iyo inoumbwa ne 85% hydrogen, 15% helium, uye zvishoma methane. Ichi chinyorwa chinoita kuti ive neiyo greenish bhuruu ruvara.
Kune gungwa rine mvura papasi rino, kunyange hazvo risina chekuita neicho chatinacho pasi pano. Denga rayo, rinoumbwa nemweya wataurwa pamusoro, unonyorovesa sezvo unodzika kudzamara wafukidza chando chose nemvura, ammonia uye gasi remethane. Takataura kuti gungwa harina kuita sechinhu chiri paPasi uye imhaka yekuti rakagadzirwa nemvura neammonia. Izvi zvinoita kuti ive neakakwira magetsi kuitisa uye zvine njodzi zvachose.
Kusiyana nemamwe magasi mahombekombe akadai saJupiter naSaturn, paUranus, chando chinonyanya kupfuura magasi nekuda kwedaro riri kure nezuva. Iwo tembiricha yakaderera zvakanyanya uye izvi zvave kutungamira nzanga yesainzi kuvadaidza mazizi mahombe. Masayendisiti haana kukwanisa kuziva chikonzero nei axis yayo yakada kudaro, kunyangwe ichifungidzirwa kuti, panguva yekuumbwa kwayo, inogona kukonana neimwe protoplanet kana rimwe dombo hombe uye kuti yakatora iyo axis semhedzisiro yekurohwa.
Ine ma satellite makumi maviri nemanomwe mune mamwe anozivikanwa kupfuura mamwe. Satellites haina kukura zvakakwana kuti ive nemhepo yavo yega. Ivo vakawanikwa zvakare neiyo Voyager 27. Vakave vanonzi Titania naOberon. Imwe inonzi Miranda yakaumbwa nemvura uye guruva chando uye ine dombo rakakwirira kwazvo muSolar System yese. Iko kukwirira kweanopfuura makumi maviri km. Iyo yakapetwa kagumi kupfuura Grand Canyon papasi redu.
Sezvauri kuona, Uranus ipuraneti isingaregi kutishamisa uye nezvazvo pachine zvakawanda zvekuziva. Izvo zvinokwanisika kuti pamwe nekuvandudzwa kwetekinoroji isu tinogona kuziva zvakanyanya nekuwedzera kuburitsa zvakavanzika zvaro zvese.
