Cov asteroid siv tsim los ntawm primordial hnub ci nebula ua ib pawg ntawm planetesimals. Planetesimals yog qhov me me precursors ntawm protoplanets. Nyob nruab nrab ntawm Mars thiab Jupiter, txawm li cas los xij, gravitational perturbations los ntawm Jupiter imbued lub protoplanets nrog ntau lub zog orbital rau lawv mus rau hauv lub ntiaj teb.
Tsuas yog li ntawd, puas yog tag nrho cov asteroids pom nyob rau hauv asteroid siv?
Feem coob ntawm asteroids uas tau cataloged yog nyob rau hauv lub asteroid siv nruab nrab ntawm lub orbits ntawm Mars thiab Jupiter; txawm li cas los xij, tsis yog tag nrho cov asteroids yog nyob rau hauv lub asteroid siv . Ob txheej ntawm asteroids , hu ua Trojan asteroids , qhia Jupiter's 12-xyoo orbit ncig lub hnub.
Tsis tas li ntawd, txoj siv asteroid nyob qhov twg thiab vim li cas? Cov asteroid siv yog ib cheeb tsam ntawm qhov chaw nruab nrab ntawm lub orbits ntawm Mars thiab Jupiter qhov twg feem ntau ntawm cov asteroids nyob rau hauv peb lub Hnub Ci System tau pom orbiting lub hnub. Cov asteroid siv tej zaum muaj ntau lab asteroids.
Hauv qhov no, muaj pes tsawg lub asteroids nyob hauv asteroid siv?
Txoj siv asteroid tseem ceeb no tuav ntau dua 200 lub hnub qub loj dua 60 mais (100 km) inch. Cov kws tshawb fawb kwv yees lub asteroid siv kuj muaj nyob nruab nrab ntawm 1.1 lab thiab 1.9 lab asteroids loj dua 1 km (3, 281 ko taw) hauv txoj kab uas hla thiab ntau lab tus me me.
Asteroids tuaj qhov twg?
Asteroids yog cov khoom rocky feem ntau pom nyob rau hauv asteroid txoj siv sia, thaj tsam ntawm lub hnub ci uas nyob ntau dua 2 ½ npaug ntawm lub hnub raws li lub ntiaj teb ua , ntawm lub orbits ntawm Mars thiab Jupiter. Cov khoom no qee zaum hu ua me ntiaj chaw lossis planetoids.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Nyob rau hauv qhov scenario yuav natural xaiv feem ntau pom tseeb tshwm sim?
Kev xaiv ntuj yuav zoo li thaum muaj kev xaiv ntau dua. Piv txwv li, kev xaiv lub siab mus tas li yog qhov tseeb tias cov kab mob yuav tsum sib tw rau cov khoom noj thiab cov peev txheej, txhais tau tias cov neeg yoog tau zoo tshaj plaws. Txawm li cas los xij, kev xaiv muaj zog tuaj yeem ua rau kev xaiv ntuj tsim tshwm sim ntau dua
Qhov twg feem ntau asteroids nyob hauv peb lub hnub ci?
Feem ntau ntawm cov asteroids uas tau teev tseg yog nyob rau hauv asteroid siv ntawm lub orbits ntawm Mars thiab Jupiter; Txawm li cas los xij, tsis yog txhua lub asteroids nyob hauv asteroid siv. Ob pawg ntawm asteroids, hu ua Trojan asteroids, qhia Jupiter's 12-xyoo orbit ncig lub hnub
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
Qhov twg ntawm cov ntsiab lus hauv qab no feem ntau pom nyob rau hauv feem ntau cov chiv?
Cov tshuaj chiv niaj hnub suav nrog ib lossis ntau tshaj ntawm peb lub ntsiab lus tseem ceeb tshaj plaws hauv cov zaub mov noj: nitrogen, phosphorus, thiab potassium. Qhov tseem ceeb thib ob yog cov ntsiab lus sulfur, magnesium, thiab calcium
