Description Belt asteroids ari renzou. Main Belt asteroids

Description of zuva nenyika dzinotenderera pariri rine ruzivo kwete chete pamusoro mapuraneti sere uye Pluto, asi zvivako zvinoverengeka, kusanganisira vakawanda yepasi pose miviri. Izvi zvinosanganisira Kuiper bhanhire, vakaparadzirwa Disc, ari Oort gore, uyewo asteroid bhandi. Ekupedzisira ichakurukurwa pazasi.

tsananguro

Shoko rokuti "asteroid" akanga chakatorwa naWilliam Herschel munyori Charlza Berni. Shoko riri yechiGiriki mavambo uye rinoreva "sezvinoita nyeredzi". Kushandisa izwi kwakadaro yave chokuita ndechokuti kudzidza dzezvimwe ari nzvimbo kuburikidza teresikopu asteroids sokuti akafanana Star: sokunge nguva kusiyana mapuraneti izvo akafanana nemavhiri.

Zvazvakadaro, hapana tsanangudzo rokuti nhasi. The chikuru maitiro chepfungwa asteroid bhandi zvinhu uye ezvirevo akafanana - saizi. Rezasi panogumira - 50 M dhayamita duku muviri Space -. Hazvina meteor. The yokumusoro muganhu - the dhayamita pakati ari pfupi nyika Ceres, anenge 1000? Km.

Location uye zvimwe

The asteroid bhandi riri pakati kutenderera Mars uye Jupiter. Nhasi kune vanopfuura 600,000 zvayo zvinhu, izvo pamusoro 400,000 vane nhamba yavo, kana kunyange zita. Inenge 98% of wokupedzisira - anoramba asteroid bhandi kure kubva zuva kubudikidza chinhambwe 2,2 3.6 AU. Kudeuka muviri pakati pavo - Ceres. Pamusangano of Mac muna 2006, iye, pamwe Pluto nedzimwe masangano akawanda akapa mamiriro pfupi nyika. Zvinotevera saizi Vesta, Pallas uye Giga pamwe Ceres anoumba 51% of zvachose kurema asteroid bhandi.

shepi

Yepasi pose muviri, vanoumba bhanhire, kuwedzera miganhu vachiri anoverengeka anokosha zvatariswa. Vose matombo zvinhu, vakatenga kutenderera dzavo vakapoteredza zuva. Zvingaonekwa kuti asteroids yakaratidza kuti, sezvo mutemo, ivo vasingapindiwo chimiro uye kuruka. Images akatora chitundumuseremusere chakasvitsa, dzibhururuke kuburikidza asteroid bhandi mugadziriro yedu yokutenderera zuva, ndikazvisimbisa zvekungofungira izvi. Maererano nevaongorori, chimiro ichi - mugumisiro kakawanda kwemotokari asteroids nemumwe uye zvimwe zvinhu.

mamiriro

To musi, nyanzvi dzinoti makirasi matatu asteroids maererano huru zvinokuvadza vari sezvamunoita dzavo:

• kabhoni (Kirasi C);
• silicate (class S) pamwe predominance pamusoro nesilicon;
• simbi (M kugiredhi).

nhoroondo yokutanga nokuda anenge 75% vose anozivikanwa asteroids. kupatsanura ichi, zvisinei, dzimwe nyanzvi hadzina sechinhu chinogamuchirika. Mukuona kwavo, boka raivapo Data regai zvakajeka kutaura izvo chaikosha chinokurira iri yepasi pose miviri asteroid bhandi.

Muna 2010, boka vanoongorora nyeredzi akaita inonakidza kuwanikwa Dhavhidhi angave akanyorerei asteroids. Masayendisiti akawana pamusoro pemvura Themis zvakakwana guru chinhu ichi vematunhu, mvura chando. The kuwana rinobvuma zvisina kunanga pfungwa yokuti mumwe matsime emvura vaduku Earth vaiva asteroids.

Other Features

Paavhareji zvazvingava panguva iyo anoramba muchadenga zuva nzvimbo iri 20 km / s. Muchiitiko chino, mumwe chimurenga huru asteroid bhandi kupedza matatu nemapfumbamwe Earth makore. Nokuti vakawanda vavo inozivikanwa zvishoma zvinodiwa muchadenga kusvika ecliptic ndege - 5-10º. Zvisinei, pane zvinhu vane trajectory kunoita pamwe nenyika ndege kuti yadzo dzichitenderera chiedza zvaitoshamisa angled anosvika 70º. chinhu ichi chakava musimboti kupatsanura pakati asteroids kupinda subsystems maviri: flat uye idenderedzwa. Kufunga kutenderera vanovengwa wokutanga mhando idukusa kana akaenzana 8º, wechipiri - kupfuura yamunenge ukoshi.

chidzoke

Negore regumi namapfumbamwe remakore masayendisiti rave akakurukura pfungwa nezvomufi Phaethon. The kure Mars kuna Jupiter zvikuru rakanaka, uye ipapo aigona rasai muchadenga imwe nyika. Zvisinei, pfungwa yakadaro nhasi anonzi usingachashandi. Modern nyanzvi vanoomerera shanduro nzvimbo, apo bhandi pamusoro asteroids, nyika sezvaikanganisika vakasagona. Chikonzero ichi muna Jupiter. The gasi Zirume ichiri munzvimbo tanga kwayo inotungamirwa ane rinokweva zvainoita nzvimbo, nhema pedyo zuva. Iye akakwezva chikamu pafuma mapazi ichi. Not akabatwa Jupiter mitumbi vakapararira kwakasiyana-siyana, protoasteroidov yakawedzera kumhanya, vakawedzera uwandu kwemotokari. Somugumisiro, havana chete akavaka mukanyiwa uye vhoriyamu, asi kunyange ichiderera. Nokufamba transformations vakadaro mukana wokuti dzomuchadenga pakati Jupiter uye Mars akava razero.

kugara simba

Jupiter uye nhasi "haasiyi oga" mashoko asteroid bhandi. giravhiti Its simba rinoita kuchinja kutenderera vamwe mitumbi. Under nawo zvaiva vanonzi havana-enda umo hapana kushanda hapana asteroids. Body achibhururuka pano nokuda mumwe kudhumhana nomumwe chinhu, ari vasiyiwa mapazi. Dzimwe nguva muchadenga iri kuchinja kuitira kuti anosiya asteroid bhandi.

mamwe zvindori

The chikuru asteroid bhandi haasi oga. At rayo pamupendero vanoiswa maviri asi zvishoma chaizvo dzidzo yakafanana. Rimwe zvindori izvi iri zvakananga pamusoro muchadenga waZeusi uye chinomiririrwa mapoka maviri zvinhu:

• "VaGiriki" mberi gasi hofori vanenge 60º;
• "Trojans" shure chete nhamba rworwendo.

A maitiro chinoratidza kwemiviri izvi ndizvo kutsiga kufamba kwavo. Zvinoita nokuda nzvimbo asteroids mu "Lagrange pfungwa", izvo zvinodzikamiswa zvose rinokweva rokuchinja izvi zvinhu.

Pasinei pfupi pedyo napedyo paNyika, kuti asteroid bhandi iri insufficiently vakadzidza uye akabata zvakavanzika zvizhinji. Chokutanga izvi, Chokwadi, ndiwo matangiro mitumbi duku pakati renzou. Pane mazano panyaya iyi, kunyange zvazvo ivo kuridza hunogutsa zvakakwana, hatina asi chisimbiso yakajeka.

Mibvunzo uye zvimwe zvinhu zviri maumbirwo asteroids. It inozivikanwa Somuenzaniso, kuti kunyange bhandi zvinhu chokuita mune zvimwe rakasiyana mumwe. Kudzidza hunhu asteroids uye dzakavapo kunokosha zvose kunzwisisa zviitiko anotangira paumbwe zuva nenyika dzinotenderera pariri sezvo tinozviziva, uye nokuda kuvakwa dzidziso pamusoro pezvakaitwa zvichiitika kure zvikamu pezvakasikwa, mune hurongwa evamwe nyeredzi.
