Uranus - the coldest nyika. Unhu zvaidiwa nyika

Uranus - the coldest yemapuraneti zuva nenyika dzinotenderera pariri, kunyange asiri kure kwazvo kubva zuva. Zirume iri rakaonekwa muna XVIII remakore. Ndiani akarivhura, uye chii vari suputniki Uranus? Chii chinokosha pamusoro ino? Description of puraneti Uranus, verenga nyaya pazasi.

Features

Ndiyo nyika wechinomwe kubva Sun kure. In dhayamita zvinonzi rechitatu, zviri 50 724? Km. Sezvineiwo, Uranus dhayamita hukuru kupfuura Neptune, pa 1840 km asi vazhinji Uranus dererei, izvo unoisa panzvimbo yechina pakati heavyweights ari renzou.

The coldest nyika chaioneka akashama ziso, asi teresikopu ine zana kuwedzera kuchaita wake kuti aone zviri nani. Suputniki Uranus funga zvokuvapfuura. Vanosvika 27, asi vari kure nenyika uye nokuda kwenhamo zvikuru kupfuura.

Uranium exchange mumwe zvina gasi hofori, uye pamwe Neptune anoumba rimwe yoga boka echando hofori. Maererano masayendisiti, gasi hofori mapuraneti yakatanga ipapa, izvo zviri chikamu yenyika.

Kuwanikwa Uranus

Nokuti kuti rinogona kuona mudenga pasina Manyiminya zviridzwa, Uranus kazhinji kururama kujeka nyeredzi. iwe zvisati kutsanangura zvinhu nyika, yakanga kuchengetwa kudenga 21 nguva. First akamuziva John Flemsid muna 1690, kuchitaurwa kuva nyeredzi panguva nhamba 34 ari renyeredzi pamusoro Taurus.

Akawana Uranus Vilyam Gershel vaiona. March 13, 1781 akacherechedza nenyeredzi teresikopu nevanhu, kureva kuti Uranus - a kometi kana dzengereka nyeredzi. Mutsamba yake, akaramba akataura kuti vakaona kometi musi March 13.

Nhau itsva muviri yokudenga amboona vakakurumidza vakapararira munzvimbo madenderedzwa zvesayenzi. Mumwe munhu akati kuti chaiva kometi, kunyange zvazvo mamwe masayendisiti kupokana. Muna 1783, Uilyam Gershel vakazivisa kuti pachine nyika.

New nyika akasarudza kupa zita vachikudza mwari wechiGiriki Uranus. mamwe mapuraneti ose akatorwa kubva muRoma mungano, uye chete zita Uranus - kubva Greek.

Kuronga uye unhu

Uranus ndiyo yakakura kupfuura Earth 14,5 nguva. The coldest yemapuraneti zuva nenyika dzinotenderera pariri hakusi yaizivikanwa isu nesimba pamusoro. Zvinofungirwa kuti inoitwa zvakaoma rakasimba chinoumba, munhu zvemapuranga chando. A pamusoro rukoko zvomumhepo.

Ice goko pamusoro Uranus hakusi nyore. Inoitwa mvura, methane uye amoniya, uye anenge 60% yenyika. Nokuda kusavapo yakasimba rukoko zvinovanetsa kusarudza Uranus mhepo. Saka, funga kwokunze mhepo gasi rukoko.

goko iri nyika ine ruvara rwebhuruu-nyoro nokuda methane, izvo absorbs tsvuku mwaranzi. Uranus ake 2 chete%. The magasi yasara, izvo kupinda mumhepo nziyo - ndiwo nehelium (15%) uye rehydrogen (83%).

Kufanana Saturn, ari coldest nyika ine zvindori. Ivo vakaumba nekaupenyu yapfuura. Pane kubvuma kuti kamwe vaiva kwemwedzi pamusoro Uranus, iro rwakakamukana nezvimedu duku zhinji. In zvachose mune 13 nezvindori, rin'i dzokunze ane chiedza yebhuruu, uchiteverwa tsvuku, uye vamwe vane pfumbu.

Sangano iri muchadenga

The coldest yemapuraneti zuva nenyika dzinotenderera pariri kubva Earth mabhiriyoni 2,8 makiromita. Neequator pamusoro Uranus riri tilted kwayo muchadenga, saka nyika yacho kutenderera ari anenge "nhema" - yakatambarara. Sokunge chihombe gasi-Ice bhora akakungurutsa kumativi nyeredzi yedu.

Planet kumativi zuva akatsauka kwemakore 84, uye zuva rayo chiedza rinovapo anenge 17 maawa. Masikati nousiku inotsiviwa nokukurumidza chete nhete Equatorial bhendi. Mune dzimwe nyika '42 rokupedzisira, uye ipapo chete - usiku.

With kuchinja. nguva refu kubva pazuva vaifungidzira kuti tembiricha musiyano inofanira zvakakwana kwazvo. Zvisinei, akanyanya kupisa nzvimbo pamusoro Uranus - zviri ikweta pane matanda (kunyange yakavhenekerwa zuva).

okunze Uranus

Sezvambotaurwa, Uranus - nyika ushamwari, kunyange Neptune uye Pluto dziri zvikuru mberi kubva zuva. tembiricha yawo yakadzikira rinosvika -224 madhigirii paavhareji mhepo rukoko.

Vaongorori akacherechedza kuti Uranus dzinoratidzwa pamwaka kuchinja. Muna 2006, kwakanga akacherechedza uye mufananidzo paumbwe mumhepo vortex pa Uranus. Masayendisiti vachangotanga kudzidza kuchinja mwaka panyika.

Zvinozivikanwa kuti pane makore ari Uranus uye mhepo. With tinosvika yamatanda mhepo nokukurumidza kunoderedza. Kunonyanyisa kumhanya yepasi mhepo inenge 240 m / s. Muna 2004, kuchinja chimbichimbi ari okunze hwakanyorwa kubva March kusvika May: wakawedzera mhepo akurumidze, dutu vakatanga, uye makore yakaonekwa kakawanda.

Govera mwaka yakadaro panyika: kumaodzanyemba zhizha kwezuva, kuchamhembe muchirimo rinenge riine uye kuchamhembe zhizha kwezuva.

Magnetosphere uye mapuraneti ubanguranyika

The chete chitundumusere-musere kuti yave kubudirira Uranus - ndiye "Voyager 2". Rakanga raparurwa nesangano NASA muna 1977, kunyanya nokuti kutsvakurudza mapuraneti kure dzedu renzou.

"Voyager 2" akakwanisa kuwana, mhete itsva kare asingaoneki Uranus, kudzidza nechivako wayo, uyewo mamiriro ekunze. Kusvikira ikozvino, vazhinji nezvaanoziva pamusoro ino kunobva mashoko vakawana pamwe midziyo iyi.

"Voyager 2" uyewo vakawana kuti coldest nyika ine magnetosphere. Yakati simba remagineti yepasi haubvi ayo geometric pakati. Zvinonzi tilted ne 59 madhigirii kubva akabatana kuti kutenderera.

Data izvi anoratidza kuti simba remagineti pamusoro Uranus riri asymmetrical, kusiyana nenyika. Pane kubvuma kuti ichi chinhu chiri chando mapuraneti, sezvo wechipiri chando vaRafa - Neptune - uyewo ane asymmetric remagineti.
