A zvomuchadenga muviri orbiting ari circumstellar - chii?

In muchadenga, vanoongorora nyeredzi vakaona zvisingaverengeki zvinhu zvakasiyana. Ndivo nyeredzi, exoplanets, nebulae, asteroids, quasars. Vamwe izvi zvinhu zviri zvimwe kutenderera. A Kutama kune mitumbi chero zvomuchadenga mukutenderera muchadenga vakapoteredza nyeredzi?

A zvomuchadenga muviri orbiting ari circumstellar - chii?

Tinofanira kutanga kufunga zvinorehwa "muchadenga". Ndicho nzira nayo muviri yokudenga rotates. Somuenzaniso, Pasi inotenderera nyeredzi yedu - zuva. Around the Earth, akavapindurawo, anoita nzira yayo kuna Moon. Zvomuchadenga muviri panguva circumstellar muchadenga zvinogona, chokutanga, nyika, chepiri asteroid, uye kometi. mitumbi zviduku zvomuchadenga havasi runoonekwa vanoongorora nyeredzi, sezvo vari zvinosanganisirwa muboka nzvimbo marara. Pashure pezvose, kutenderera zvavo nokuda mukanyiwa duku kwemiviri yokudenga achava huru maitiro - maitikiro. Chero muviri zvikuru uremu huchachinja trajectory kufamba kwavo - rakamira.

Ivo vane wakaiswa muchadenga satellites Nyika, akasika munhu. In chimiro akafanana elongated ellipses. The dzepedyo akajekerwa muchadenga ane perigee, uye kure zvikuru - Apogee. Mumwe zvomuchadenga muviri panguva circumstellar muchadenga zuva zvinopfakanyika chete negwara. It zvinoshamisa chokwadi pamusoro dzaro, iyo uchapupu mumwe hypotheses vayo mavambo. Maererano nepfungwa iyi, zuva nenyika dzinotenderera pariri yakabuda kubva gore guruva uye gasi. Kuwedzera kune zviuru Mapuraneti duku, asteroids, kunyange kufamba chete negwara.

Asteroids ari Solar System

Asteroids masayendisiti mudane miviri yokudenga ine dhayamita kupfuura mamita 30. Ivowo, vangava satellites zvavo. Shoko "asteroid" akanga chinorehwa nemashoko wenziyo Charlzom Berni uye zvomuchadenga William Herschel, rinoreva "sezvinoita nyeredzi". Paakaona asteroids chitarisiko chavo anenge indistinguishable kubva nyeredzi. Nyeredzi yakanga yakaita anopenya mavhiri, uye asteroids vanounzwa muchimiro pfungwa nechiedza. Pari, chikuru musayenzi kufarira kune vanoongorora nyeredzi, vanonzi asteroid bhandi. Ndivo rimwe guru nzvimbo zvinhu munyika renzou. Inside zuva nenyika dzinotenderera pariri Nde asteroid bhandi iri pakati kutenderera nyika Mars uye Jupiter.

Comets - pamwe trajectory kwemiviri yokudenga

Chiizve anogona kuwanika pamusoro zvomuchadenga muviri orbiting circumstellar? Mhinduro ingaita zvinoshamisa, asi - a kometi. mitumbi izvi zvomuchadenga uyewo dzitendererane mukutenderera muchadenga vakapoteredza zuva. Translated kubva "kometi" mutauro wechiGiriki rinoreva "nyeredzi mvere". Sezvo kometi anosvika zuva kupenya, uye mugove wake dzengereka iri kudhonzwa. Bright comets zvinogona kuonekwa denga chinoabatsira. The nguva majana miviri yokudenga izvi akapoteredza Sun ingabva makore mashomanana zvikuru sezvo emakore.

Kana kometi ari kure Sun, hazvina zvinoonekwa kubva Earth. A pedyo, zvinova nyore kuti vanhuwo mucherechedzi. Nokuti kokutanga kutenderera kakawanda comets akapoteredza Sun rakaonekwa musayendisiti Halley muna XVII remakore. Achiona kometi, akawana kuti chinofamba nenzira sezvo mamwe mapuraneti ari renzou. Halley akafanotaura kudzoka musi kometi kuna Earth vacherechedzi. Vachifanotaura nyanzvi sowakajeka anoruramiswa.

Nakhodka masayendisiti asteroid orbiting nyeredzi kufa

Muna October 2013, nyanzvi vakanga vawana muviri yokudenga iri circumstellar orbiting kure kufa nyeredzi imwe. Chinovheneka anonzi G61 atova ndorwevaya boka dwarfs chena uye kubviswa zuva nenyika dzinotenderera pariri nechokure makore chiedza anenge mamiriyoni 150. Zvomuchadenga muviri kuti inotenderera nyeredzi ichi, yakanga iri asteroid, uko masayendisiti akawana guru yakawanda mvura reserves. Izvi zvakawanikwa akabvumira vanodzidza nezvenyeredzi vanofungidzira kuti munyika kamwe pangava mapuraneti akafanana needu.

Ichi chiitiko rokutanga apo kunze mugadziriro yedu yokutenderera zuva maviri anokosha zvinhu nokuda chidzoke upenyu yakawanikwa - paneshongwe nomumativi mvura, iyo ine zvomuchadenga muviri orbiting ari circumstellar. Izvi zvinoratidza kuti kamwe pakanga upenyu. Ndezvipi zvikonzero yaigona kutora munyika ino - masayendisiti anogona chete zvokufungidzira. Analysis kufa asteroid akaratidza kuti hwakanga 26% mvura. By izvi zvakafanana pfupi nyika iri Solar System - Ceres. Zviri asteroid Ceres uye hama kurema mvura pamusoro pavo ndiko kupfuura Panyika.

G61 uye zvomuchadenga muviri orbiting ari circumstellar - mhinduro tinoiwana paNyika ramangwana

The Earth iri chaizvoizvo chakaoma nyika. 0.02 chete% ayo vakawanda yose ndiyo mvura. The masayendisiti anodavira kuti nyanza aonekwa mushure Earth yakatangwa. By kubvuma, vatsvakurudzi, Pasi aigona kunangana vazhinji mvura-vapfumi asteroids. First Kugutsikana chinhu zvomuchadenga muviri orbiting ari circumstellar, masayendisiti akadzidza pamusoro ramangwana revanhu. Ivo vanotaura kuti mushure kwemakore mabhiriyoni 6, sezvakanga nomutorwa vatsvakurudzi kudzidza matombo masarasara orbiting yedu zuva rwounofa, uye vachauya pakugumisa kuti Pasi aimbova kukwanisa kutsigira upenyu.
