Hounds Alpha yog ib lub tshuab binary zoo nkauj tshaj plaws, raws li ntau tus kws tshawb fawb. Nws lub ntsiab tivthaiv yog dawb-xiav kublub hnub qub tseem ceeb. Nws yog tus qauv ntawm cov chav kawm ntawm kev sib txawv luminaries ntawm tib lub npe. Cov laj thawj uas ua rau muaj kev hloov pauv ntawm qhov ci ntawm lub hnub qub yog nws txoj kev sib hloov thiab muaj zog hlau nplaum heev. Lub tom kawg tshaj qhov analogous parameter ntawm lub hnub los ntawm ib puas lub sij hawm. Lub ci ci ntawm lub hnub qub nrog lub sijhawm ntawm 5.47 hnub txawv ntawm + 2.84 m txog + 2.94 m. Cov hlau nplaum ntawm lub luminary, ntxiv rau cov kev hloov pauv no, tsim cov pob me me ntawm qhov loj thiab qhov tsis sib xws hauv cov duab ntawm qhov chaw piav qhia.
Qhov thib ob ntawm qhov system yog daj daj lub ntsiab lus dwarf.
Beta
Lub hnub qub ci ntsa iab tom ntej hauv cov qauv hnub qub no hu ua Chara. Nws yog ib tug daj daj thiab belongs rau spectral class G. Nyob rau hauv ntau yam, lub hnub qub zoo li lub hnub.

Ntxhais khoom zoo
Hounds Dogs yog ib lub hnub qub uas muaj ntau qhov kev xav paub cosmic tsim ntxiv rau cov luminaries. Cov no yog galaxies, nebulae, thiab globular pawg. Ib tug ntawm lawv yog M51. Qhov no yog lub galaxy hu ua Whirlpool. Nws raug cais tawm ntawm lub ntiaj teb los ntawm kwv yees li 23 lab lub teeb xyoo. Qhov peculiarity ntawm cov khoom yog tias nws muaj ob lub galaxies. Qhov loj tshaj ntawm lawv, NGC 5194, muaj ib tug pronounced kauv qauv. Ib ntawmcaj npab so ntawm tus khub galaxy NGC 5195. Cov tswv ntawm lub tsom iav raj amateur yuav xav paub tias Whirlpool yog tib yam khoom uas koj tuaj yeem pom cov qauv kauv yam tsis muaj cov cuab yeej tshaj lij.
Ntau tus kiv cua ntawm astronomy paub zoo txog lub ntiaj teb pawg M3. Nws muaj ntau dua 500 txhiab lub hnub qub. Nws yog qhov pom tau zoo heev los ntawm lub koob yees duab, yog tias nws nyob deb ntawm lub nroog teeb pom kev zoo.
Nws tsis yog qhov xwm txheej uas ntau lub koob yees duab tsom mus rau lub hnub qub Canes Venatici. Cov duab ntawm cov khoom los ntawm nws thaj chaw, ntxiv rau cov npe, muaj cov galaxies zoo nkauj xws li M63 (Sunflower galaxy), M106 lossis M94. Tsis tas li ntawd, tsis yog txhua yam tseem paub rau cov kws tshawb fawb txog hnub qub ntawm cov qauv xilethi-aus. Zoo siab tias Hounds of the Dogs muaj ntau yam surprises hauv khw rau peb.
