Zoo li feem ntau meteorites, chondrites keeb kwm nyob rau hauv lub asteroid txoj siv uas kev sib tsoo thiab gravitational perturbations muab lawv mus rau hauv lub ntiaj teb-hloov orbits. (Tshwj xeeb chondrites, tshwj xeeb, yog los ntawm S-class asteroids.) Chondrites tsim kwv yees 4.56 billion xyoo dhau los ua ib feem ntawm kev tsim ntawm lawv niam txiv asteroids.
carbonaceous chondrites tuaj qhov twg?
Feem ntau cov carbonaceous chondrites tau xav tias yog los ntawm qis-albedo, C-hom asteroids, uas yog hom ntau tshaj plaws ntawm 2.7 thiab 3.4 AU (Tswb li al., 1989), CM chondrites tuaj yeem muab tau los ntawm qhov hloov pauv C-zoo li lub hnub qub hu ua G-hom (Burbine li al., 2002).
hnub nyoog pes tsawg carbonaceous chondrite meteorite?
Carbonaceous chondritic meteorites yog cov ntaub ntawv tseem ceeb ntawm Hnub Ci Hnub Ci thiab qhov chaw xa dej rau lub ntiaj teb. Cov kua dej ntws los ntawm cov niam txiv lub cev ntawm cov meteoritespaub tias tau tshwm sim thaum ntxov hauv Solar System keeb kwm (thawj <4 lab xyoo).
Thaum twg chondrite tsim?
Zoo li pob zeb hauv ntiaj teb, pob zeb qhov chaw tuaj yeem ua rau tsis pom kev, sedimentary, lossis metamorphic. Chondrite Meteorite yog ib feem sedimentary thiab ib feem igneous. Raws li lub pob zeb qub tshaj plaws hauv Tsev khaws puav pheej, nws tsim txog 4.5 billion xyoo dhau los.
carbonaceous chondrite tsim li cas?
Cov zaub mov presolar no tej zaum tsim tau thaum lub sij hawm tawg ntawm ib lub supernova nyob ze los yog nyob ib ncig ntawm lub pulsating liab giant(ntxivmeej: lub hnub qub AGB) ua ntej lawv nkag mus rau hauv huab ntawm qhov teeb meem uas peb lub hnub ci tau tsim.
