NASA / ESA Hubble Space Telescope tau muab cov duab ntawm Saturn hauv ntau xim , los ntawm dub-thiab-dawb, rau txiv kab ntxwv, rau xiav, ntsuab, thiab liab.
Kuj Paub, Saturn nrhiav tau li cas? Thawj qhov kev soj ntsuam ntawm Saturn Los ntawm lub koob yees duab tau tsim los ntawm Galileo Galilei hauv xyoo 1610. Nws thawj lub koob yees duab yog qhov hnyav heev uas nws tsis muaj peev xwm paub qhov txawv ntawm lub ntiaj teb lub nplhaib; es nws xav tias lub ntiaj teb no yuav muaj pob ntseg los yog ob lub hli loj ntawm ob sab ntawm nws.
Tom qab ntawd, ib tug kuj yuav nug, Dab tsi yog Saturn?
Saturn tsis yog ib yam khoom zoo li lub ntiaj teb, tab sis yog hloov lub ntiaj chaw loj heev. Nws yog ua nce ntawm 94% hydrogen, 6% helium thiab me me ntawm methane thiab ammonia. Hydrogen thiab helium yog dab tsi feem ntau hnub qub yog ua los ntawm . Nws yog xav tias tej zaum yuav muaj ib tug molten, rocky core hais txog qhov luaj li cas ntawm lub ntiaj teb tob nyob rau hauv Saturn.
Qhov loj ntawm Saturn yog dab tsi?
58,232km:ua

Dab tsi yog 8 lub ntsej muag ntawm octahedron?
Nyob rau hauv geometry, ib tug octahedron (plural: octahedra) yog ib tug polyhedron nrog yim lub ntsej muag, kaum ob ntug, thiab rau vertices. Lo lus feem ntau yog siv los xa mus rau qhov tsis tu ncua octahedron, Platonic cov khoom tsim los ntawm yim daim duab peb sab sib npaug, plaub qhov sib ntsib ntawm txhua qhov vertex
Lub ntsej muag zoo li cas muaj 5 lub ntsej muag?
Hauv geometry, pentahedron (plural: pentahedra) yog polyhedron nrog tsib lub ntsej muag lossis sab. Tsis muaj lub ntsej muag-transitive polyhedra nrog tsib sab thiab muaj ob hom topological txawv. Nrog lub ntsej muag polygon tsis tu ncua, ob daim ntawv topological yog cov square pyramid thiab triangular prism
Dab tsi yog qhov flux los ntawm ib lub ntsej muag ntawm lub voos xwmfab?
Teb thiab piav qhia: Cov hluav taws xob flux los ntawm ib sab ntawm ib lub voos xwmfab vim yog tus nqi taw tes yog & rho tawm; 32000 V ⋅ m − 32 000 V ⋅ m
Lub ntsej muag yog dab tsi?
Nyob rau hauv cov khoom geometry, lub ntsej muag yog lub tiaj tus (planar) nto uas tsim ib feem ntawm tus ciam teb ntawm cov khoom khoom; ib tug peb-dimensional khoom bounded tshwj xeeb los ntawm lub ntsej muag yog ib tug polyhedron
Koj pom thaj tsam ntawm lub ntsej muag siv lub ntsej muag li cas?
Qhov chaw saum npoo yog qhov sib npaug ntawm thaj chaw ntawm txhua lub ntsej muag (lossis qhov chaw) ntawm 3D duab. Ib lub cuboid muaj 6 lub ntsej muag. Txhawm rau nrhiav thaj chaw saum npoo ntawm lub cuboid, ntxiv cov cheeb tsam ntawm tag nrho 6 lub ntsej muag. Peb tseem tuaj yeem sau qhov ntev (l), dav (w), thiab qhov siab (h) ntawm lub prism thiab siv cov qauv, SA = 2lw + 2lh + 2hw, txhawm rau nrhiav thaj chaw saum npoo
