Lawv yog ob lub cev saum ntuj ceeb tsheej orbiting peb lub hnub, thiab lawv ob leeg ua tau muaj txawv txawv orbits, tej zaum straying ze rau lub ntiaj teb los yog lwm yam ntiaj chaw. Thaum asteroids muaj cov hlau thiab cov khoom siv pob zeb, comets yog tsim los ntawm cov dej khov, plua plav, cov khoom siv pob zeb thiab cov organic compounds.
Ib yam li ib tug yuav nug, ua li cas cov comets thiab asteroids zoo ib yam?
Qhov sib txawv tseem ceeb ntawm asteroids thiab comets yog lawv muaj pes tsawg leeg, raws li nyob rau hauv, dab tsi lawv yog ua los ntawm. Asteroids yog ua los ntawm cov hlau thiab cov khoom siv pob zeb, thaum comets yog ua los ntawm cov dej khov, plua plav thiab cov khoom siv pob zeb. Ob leeg asteroids thiab comets tau tsim thaum ntxov hauv keeb kwm ntawm lub hnub ci system txog 4.5 billion xyoo dhau los.
Tsis tas li ntawd, dab tsi asteroids thiab comets muaj nyob rau hauv ntau quizlet? Asteroids thiab comets yog ob qho tib si ua los ntawm cov khoom siv pob zeb thiab dej khov, tab sis asteroids yog loj loj dua comets . Dab tsi ua astronomers txhais tau tias thaum lawv xa mus rau "qhov khoob" hauv qhov asteroid txoj siv sia ntawm Mars thiab Jupiter? Asteroids zoo li zam qee qhov orbits nyob ib ncig ntawm lub hnub, tsim "khoom" hauv lub orbits uas asteroids ua tau muaj.
Ib yam li ntawd, dab tsi comets thiab asteroids thiab meteors muaj sib xws?
Comets , meteors thiab asteroids muaj ob peb yam hauv feem ntau . Ua ntej, lawv ntseeg tau tias yog cov khoom seem uas tsim lub hnub thiab cov ntiaj chaw. Raws li comets taug kev ze rau lub hnub, qee qhov dej khov yaj tawm thiab dhau los ua roj. Cov txheej txheem melting no ua rau me ntsis ntawm cov plua plav thiab cov khib nyiab mus rau tom qab lub hnub qub.
Asteroids thiab comets tuaj qhov twg?
Asteroids thiab comets raug suav hais tias yog cov seem ntawm cov huab cua loj heev ntawm cov pa roj thiab hmoov av uas condensed los tsim lub hnub, ntiaj chaw, thiab lub hli li ntawm 4.5 billion xyoo dhau los. Niaj hnub no, feem ntau asteroids orbit lub hnub nyob rau hauv ib tug nruj packed siv nyob rau hauv nruab nrab ntawm Mars thiab Jupiter.
