Ceres - ndi dziko kapena asteroid? M'nthano ndi nyenyezi kufunika

Ceres - nyenyezi yaing'ono dziko, ili mkati waukulu asteroid lamba pakati pa Mars ndi Jupiter. Dzina la dziko nyenyezi yaing'ono unatchedwa wamkazi wachiroma wa zaulimi ndiponso yobereketsa Ceres (Ceres). Wopangidwa makamaka a dongosolo miyala ndi matalala, lili pafupifupi 950 Km awiri.

Kupezeka kwa dziko nyenyezi yaing'ono

Ceres - ndi asteroid kapena dziko panobe? Mwangozi anapeza mu 1801 ndi zakuthambo Italy Dzhuzeppe Pyatstsi osadziwika lakumwamba thupi, poyamba ankadziwika monga nyenyezi, kenako kopanda kuti ndi asteroid. Mu 2006, bungwe la International zakuthambo Union wapanga latsopano kalasi ya zinthu mu dongosolo la zowalitsa, lotchedwa mapulaneti nyenyezi yaing'ono. Ceres chinaoneka monga dziko, ngakhale nyenyezi yaing'ono ndi pamodzi ndi Vesta, Juno ndi ena.

maonekedwe ndi zikuchokera dziko

Asayansi akukhulupirira kuti Ceres ali pakati miyala ndi achisanu chovala makilomita 100 wandiweyani. Ena a iwo amakhulupirira kuti madzi wosanjikiza madzi makilomita kiyubiki 200 miliyoni. kopanda izi zimawapangitsa nyenyezi yaing'ono dziko nkhani yosangalatsa kuphunzira kuchokera ofufuza kuyang'ana zizindikiro za moyo zakuthambo. NASA anayambitsa phunziro yakuti "Don" amene ntchito anali kupanga malo kuyenda molunjika mu lamba asteroid kusonkhanitsa deta za mbali ya padziko ndi zikuchokera nyenyezi yaing'ono mankhwala.

kusanthula kawalidwe anasonyeza pamaso pa kufufuza mchere ndi madzi, ndi m'madera ena, zikuoneka kuti ayezi chivundikiro nayenso. Malinga zakuthambo, dziko Ceres (chithunzi NASA kupereka zifukwa kulingalira) amakhala ndi madzi posungira manambala kuposa Padziko Lapansi, ndipo iwo amakhala malo ofanana ndi gawo la India, Argentina, kapena 4% a padziko mwezi. Wosanjikiza akunja ndi porous ndithu, ndi pamaso mwina dongo ndipo carbonate miyala chitsulo wolemera.

NASA kafukufuku

alibe kuenderera mu kukana chakuti dziko Ceres - ndi asteroid, mmodzi wa iwo kuti ndizipange izo mu kanjira. Makina NASA spacecraft "Dawn" analowa mapulaneti March 6, 2015. zithunzi chinthu anatengedwa mu January 2015, pamene chombo chidafika lapamtima la Ceres. Mu kamera, awiri mawanga chowala anasindikizidwa mu umodzi wa zimaphala lapansi. March 3, 2015, mneneri NASA ananena kuti mwina kuda ayezi kapena mchere. May 11, 2015 panali zithunzi za kusamvana apamwamba, amene anasonyeza nambala yaikulu ya mawanga chowala.

Ice lawi chitukuko ndi Geological

Zimaonekera Ceres ndi ofunda. Zolemba malire kutentha anafika -38 ° C. Ice pa kutentha kwambiri osakhazikika. Chifukwa kuzipenya ultraviolet wa spacecraft ndi IUE anapezeka kwambiri kuchuluka kwa ayoni hydroxide pa North Pole dzikoli. Iwo ndi mankhwala a evaporation wa madzi chifukwa cha kutentha kwa dzuwa ultraviolet.

Geological chitukuko miyala ndi achisanu pamwamba ankadalira magwero kutentha Kufikika mkati ndi pambuyo mapangidwe amenewa danga chinthu monga Ceres (nyenyezi yaing'ono dziko). njira zimenezi ndi N'kuthekanso kuti kugwirizana ndi ena kayendedwe mapiri tectonic. Ice mapangidwe padziko pang'onopang'ono anawuka, kuphimba ndi mchere monga clays ndi carbonates.

Planet Ceres nyenyezi ndi nthano

Mu nyenyezi, Ceres (dziko) ndi chizindikiro cha kholo ndi mwana kuyankhulana. Palibe chikondi chachikulu padziko lapansi kuposa chikondi cha mayi mwana wawo. Mu nyenyezi zachipatala Ceres kugonjetsedwa akuimira vuto zachilengedwe ubereki, chonde. Pamene dziko thupi lakumwamba ndi udindo ntchito, khama ndi luso mokwanira kukwaniritsa awo ntchito akatswiri maganizo zipatso, ntchito analenga.

Nthano Ceres (dziko) Roma ofanana Greek wamkazi Demeter, mlongo wake wa Zeu (Jupiter). Iye ali mayi wa dziko lonse lapansi, ndipo ndi udindo yokolola, kuphika, chikondi, kuchuluka ndi chitonthozo. Iye ndi mulungu wa malimidwe, ndi mwana wake wamkazi Persephone (Proserpina) anali kwathu ndi Pluto, amene anafuna kukakamiza iye kuti akwatiwe naye, Ceres ndi chidwi kwambiri ndi kufunafuna mwana wake wamkazi kuti waponya chisamaliro cha dziko lapansi, chimene chakhala ozizira kwambiri. Choncho yodziwika m'dzinja ndi yozizira nyengo pa chaka. Mu kasupe ndi chilimwe cha Persephone anabwerera Herme mayi, ndi onse apadziko bloomed.

Ceres - ndi nyenyezi yaing'ono dziko pa ndime ndi Pluto, amene ali ofanana player ndi ophunzira ena danga m'munda wa dongosolo la zowalitsa. Ndi yaikulu ya onse mapulaneti kakang'ono, kotsegula anthu.
