Vesta - imwe asteroid chaioneka chinoabatsira

Vesta - imwe asteroid, muzvinhu zvakawanda zvinonakidza. Ndiyo chete chinhu zvokuti kunogona kuonekwawo pamwe chinoabatsira. By uremu, uye kukura Vesta kupfuura zvimwe kuvazivisa asteroids iri nzvimbo pakati kutenderera Jupiter uye Mars. By parameters ayo zviri kunyange pedyo pfupi nyika. Iri huru asteroid bhandi, Vesta anotaura miviri kuumbwa yakakomba nguva sezvo Earth, uye naizvozvo, angamuudza zvakawanda pamusoro yakapfuura ezvinhu edu kure.

kuwanikidza

Vesta - imwe asteroid, yakawanikwa muitiro kutsvaka nyika pakati Mars uye Jupiter. Maererano dzidziso, kuparadzira kutenderera ari nzvimbo yakapoteredza pezuva pasi dzimwe mitemo. All anozivikanwa pakutanga pakati XIX remakore nyika zvinopinda dzidziso iyi. The chete Kunze ndiye Jupiter uye Mars. The yakakura nzvimbo pakati pavo kwaiva kuviga risingazivikanwi nyika. Panguva yake kutsvaka zvakawanda pezvokuvamba Main dzakafukurwa asteroid bhandi.

Vesta yakawanikwa 1807 ne Heinrich Wilhelm Olbers. Mumwe musayendisiti, Carl Gauss, akamupa zita yeRoma mwarikadzi wechoto. The zita akaomerera uye richiri kushandiswa nanhasi.

parameters

Mushure Ceres zvakabatanidzwa nemapuraneti zvipfupi, Vesta kukura ari panzvimbo yechipiri pakati asteroids pashure Pallas. parameters Its - 578 × 560 × 458? km. Kuoneka asymmetry kuti chimiro, nokudaro kudzivisa mutobvu kuti pfupi nyika. By uremu (2.59 × 10 ²⁰ kg) zviri mberi uye palladium, ndiko kuti, muna huru asteroid bhandi runopfuura mune parameter ichi, asi zvose zvakafanana Ceres.

Ko asteroid Vesta muchadenga?

Asteroids vasiri chete aunonyanya boka mitumbi yokudenga. Kubva mapuraneti vakasiyana pane dzinoverengeka parameters: saizi, chimiro, uremu uye zvichingodaro. Zvinoitwa ane asteroid, haana kumubvumira kuti abate gasi hamvuropu. Saka mhinduro yomubvunzo wokuti, "Ko asteroid Vesta, mhepo iri" - kunaka. Zvikuru tenuous goko negasi aripo Ceres. Zvimwe miviri iri huru mapazi haagoni vanozvirova zvakadai anozivikanwa sezvo asteroid Vesta. Rine kuitika Earth, Venus, Mars, gasi hofori uye dzimwe shamwari. Asteroids nokuti zvinondiremera diki.

How kuona asteroid Vesta?

Vesta nokuda kwahwo zvinogona kuonekwa chinoabatsira. Kunyange zvazvo zviri muduku pakukura Ceres uye Pallas, asi kunoratidzwa guru reflectivity. Other asteroids pamwe Earth haichaonekwi pasina chinokosha michina.

The yakanakisisa nguva kutsvaga asteroids mudenga - kushorwa mazuva, kana achisvika shoma daro paNyika. Munguva iyi nguva, ayo Gloss ichiwedzerwa kuti mamita 5,1 (shoma kukosha parameter ichi - 8,5 m). Last nguva nhaurwa yakadaro kwakaitika April 2014.

Vesta ari pedyo shoma daro redu kamwe 3-4 makore ose. Pasina teresikopu kuchengeta zvinokwanisika chete mumamiriro ezvinhu ose maonero akanaka. Muchiitiko chino, hazvina wakasiyana zvavo nyeredzi.

chitsungo

The muchadenga pamusoro Vesta iri romukati chikamu chikuru asteroid bhandi. chimiro charo chete zvishoma kumwezve - iri rinenge denderedzwa akakwana. The muchadenga kunoratidzwa zvishoma kurereka kuna ecliptic ndege. Vesta anoita chimwe chimurenga yakapoteredza Sun mumakore 3,6. Panguva iyoyo panguva kufamba kwavo muchadenga yepasi hakuzopfuuri asteroid.

Space vachiongorora Dawn

Muna 2011, muna July, Vesta akapfuura pfungwa shoma kure redu. Nguva iyi yakashandiswa kwenguva hwakadzama kudzidza asteroid. Kare muna 2007, ndakaenda Vesta, Dawn AMC. Basa iri chikwata - kudzidzwa asteroid, uye pfupi nyika Ceres.

A raundi muchadenga Vesta Dawn akauya July 16, 2011. By December 12, zvasvika shoma kukwira pamusoro asteroid. Pakati mabasa ose chikwata vaiva nokuyerwa ari rinokweva munda, vakatsunga chakarondedzera neutrons uye wegamma-mwaranzi dzinowanika kuwa yepasi pose mwaranzi pamusoro asteroid Vesta. Photos of chinhu vakatanga kuuya pasi December rechi13.

Dawn AMC akabva asteroid 5 September 2012 uye akaenda Ceres. To musi (December 2015), muchina anoramba kushanda pazuva muchadenga ari pfupi nyika.

showplace

Vesta - imwe asteroid nokungwarira "iongororwe" teresikopu "Hubble". The zveBhaibheri yaiitwa muna 90-ies wekupedzisira remakore. "Hubble" vakadzidza pechiso asteroid. The unoyevedza chikamu zvokuyamura akatendeuka akabudisa mwena hombe, yainzi rheasilvia. Next, anofungidzirwa zvasara kubva kudhumhana, dzinoratidzwa dhayamita ine 460? Km uye kudzika 13 km. Masayendisiti achiri haagoni kupindura mubvunzo sei Vesta akakwanisa kurarama akarova yakadaro.

Dawn AMC akadzidzawo mamiriro mwena. Maererano zvekungofungira masayendisiti rheasilvia vakaumba makore bhiriyoni akapfuura. Pool mwena aoma inovanza munhu aitodada kupfuura yekare kwechirwere, mumwe mwena ainzi Veneneyya. Pakati rheasilvia iri pachikomo 22 km yakakwirira uye 180? Km mu dhayamita. By parameters ayo zviri mberi hofori Olympus musi Mars, kare vaiona zvepamusoro anozivikanwa gomo iri renzou.

Masayendisiti dzinofungidzira kuti mashoko vabudiswa nokuda nehana, vakashumira sezvo mashoko panowanikwa zvinhu uye neboka mhuri Vesta asteroids V.

Vaongorori anorayira pfungwa dzake zvinhu zvakadai vanogona kuudza yakawanda pamusoro nguva apo zuva nenyika dzinotenderera pariri akanga achiumba. Vesta - imwe asteroid, ayo akafanana pedyo mapuraneti Pasi-kufanana. Kazhinji kacho achakuudza vanodzidza nezvenyeredzi kudzidza zvakawanda yakapfuura chidimbu kwedu Galaxy kure.
