Tsis tas li ntawd, ob hom comets yog dab tsi thiab lawv nyob qhov twg?
Comets muaj nyob rau hauv ob lub ntsiab thaj chaw ntawm lub cosmos: lub Kuiper txoj siv thiab lub Oort huab. Lub sijhawm luv comets -- comets uas nquag rov qab mus rau lub hnub ci system - tej zaum keeb kwm los ntawm thaj chaw hu ua Kuiper txoj siv. Txoj siv sia no nyob hauv lub hnub ci lub hnub ci lub dav hlau ecliptic, dhau ntawm lub orbit ntawm Neptune.
Qhov thib ob, ob lub comets nto moo tshaj plaws yog dab tsi?
- Halley lub Comet. Halley's Comet yog lub npe nrov tshaj plaws ntawm tag nrho cov comets.
- Cov khau khau Levy-9.
- Hyakutake.
- Hlo Bopp.
- Comet Borrelly.
- Comet Encke.
- Tempel-Tuttel.
- Comet Wild 2.
Thiab cov lus nug yog, muaj pes tsawg hom ntawm comets muaj nyob?

Comet Hale-Bopp), comets nrog tsis muaj ntsiab lus orbit (The Great Comet ntawm 1106), thiab poob comets (5D / Brossen), tso tawm raws li P (periodic), C (tsis yog caij nyoog), X (tsis muaj orbit), thiab D (poob).
Leej twg yog 2 lub npe nto moo comets?
Lub comet muaj npe tom qab Askiv astronomer Edmond Halley , leej twg tshuaj xyuas cov lus ceeb toom ntawm lub comet tuaj txog Lub ntiaj teb Nyob rau hauv 1531, 1607 thiab 1682.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog comets thiab asteroids muaj sib xws?
Asteroids thiab comets muaj ob peb yam sib xws. Lawv yog ob lub cev saum ntuj ceeb tsheej orbiting peb lub hnub, thiab lawv ob leeg tuaj yeem muaj qhov txawv txav txawv txav, qee zaum mus deb ntawm lub ntiaj teb lossis lwm lub ntiaj teb. Thaum lub hnub qub muaj cov hlau thiab cov khoom siv pob zeb, cov comets yog ua los ntawm cov dej khov, plua plav, cov khoom siv pob zeb thiab cov organic compounds
Dab tsi yog qhov tshwj xeeb ntawm comets?
Comet Facts. Comets, zoo li asteroids, yog lub cev me me saum ntuj ceeb tsheej uas orbit lub hnub. Txawm li cas los xij, tsis zoo li asteroids, comets yog tsim los ntawm cov ammonia khov, methane lossis dej, thiab tsuas muaj cov khoom siv pob zeb me me xwb. Raws li qhov tshwm sim ntawm qhov muaj pes tsawg leeg comets tau muab lub npe menyuam yaus ntawm 'dawb snowballs
Dab tsi yog asteroids meteors thiab comets?
Meteors thiab Meteorites Thaum taug kev los ntawm qhov chaw, asteroids qee zaum sib tsoo nrog ib leeg thiab tawg mus rau hauv me me. Comets plam plua plav thaum lawv taug kev hauv lub hnub ci. Cov 'kev tawg' no ua rau muaj ntau qhov me me thiab cov tawg, hu ua meteoroids, uas orbit lub hnub
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
