'''Dayax''' ([[ingiriis]]: Moon) waa [[duni|aduunyo yar]] oo ku wareegta [[Meere]] ama wax ka ween dayaxa.
Ugu yaraan, meere kasta wuxuu leeyahay hal dayax ama in ka badan.

[[Dhul|Dayaxa dhulku]] waa kan ugu weeyn dhamaan dayaxyada [[meere]]yaasha [[Bahda Midaysay Qoraxdu]] laba odhan karo wuxuu ka wayn yahay meereyaasha yaryar qaarkood. 
Cufis-jiidadka u dhexeeya dhulka iyo dayaxa ayaa keena [[bad|mowjadaha badaha]], taas mi la mid ah ayaa keentay isku-xidhnaanshaha labadooda. 

Dayaxa oo ku socda xawaare dhan 1.022 kilomitir ilbiriqsigiiba, ayaa waxay ku qaadataa [[maalin|27 maalmood]], [[saacad|7 saacadood]] iyo [[daqiiqad|43 daqiiqo]] in uu hal mar ku wareego dhulka. 

Dhinaca kale, isku wareega dayaxu (circumference) waa 10, 921 km; [[cuf]]kiisuna waa 2.1958 ×<br /><span>10<sup>10</sup> km<sup>3</sup></span> halka [[mug]]iisu yahay 7.3477 ×<br /><span>10<sup>22</sup> kg</sup></span>. 
Maadaama dayaxa cirkiisu aad u khafiif yahay falaadhaha qoraxduna toos u soo taabtaan oogada dayaxa ayaa [[heerkul]]kiisu aad u sareeyaa ugu yaraan waa 100 Kalfin ugu badnaana wuxuu gaadhaa 390 K.

Jidhka dayaxu wuxuu ka samaysan yahay [[Isku dhis|iskudhisyo]] kala duwan kuwaas oo u badan [[curiye]]yaasha kala ah: [[curiye|Argon]], [[Hiliyaam]], [[Sodhiyaam]], [[Botashiyaam]], [[Haydarojiin]] iyo ''Raadon''. 

Markii ugu horeeysay taariikhda bani-aadamka, sanadkii 1959kii ayaa [[Dayax Gacmeed]] [[Ruush]]ku leeyahay tagay dayaxa. Ka dib, 1968dii ayaa qofkii ugu horeeyay cagaha saaray dayaxa kaas oo ka socday Dawladda [[Maraykan]]ka. 
Sanadkii 2004 wixii ka dambeeyay ayaa wadanada [[Jabaan]], [[Hindiya]], [[Shiinaha]] iyo [[Yurub]] saldhigyo ka sameeysteen dayaxa. 

Inkasto dayaxu lahayn [[cir|cir sare]] oo ka difaaca [[kul]]ka [[qorax]]da, cilmi baadhis la sameeyay waxay muujisay in dayaxu leeyahay [[biyo]] laga heli karo [[cidhif]]yada dayaxa iyo oogada sare dhexdeeda.

[[Dayaxa meere]] waa duni yar oo ka samaysan [[dhagax]]aan, [[neef]] iyo [[isku dhis]]yo kale taasi oo ku wareegta [[meere]]. Tusaale ahaan, [[dayax]]a meeraha [[dhul]]ka.

Meeraha [[Docay]] wuxuu leeyahay [[dayaxa docay|14 dayax]]. 

Si kastaba ha ahaatee, [[duni|duunyooyinka yar]] qaar ka mid ah waxay leeyihiin dayaxyo yaryar oo ku wareega ayaga.

Waxaa la aaminsan yahay in dayaxyada qaar ay ka jirto [[nolol]], sida dayaxa [[Titan]] ee [[Cirjeex]] iyo bisha [[Triton]] ee meeraha [[Docay]], laakiin lama hubo ineey jirto midaasi.<ref name="almagest">{{cite journal |first=Bernard R. |last=Goldstein |title=Saving the phenomena: the background to Ptolemy's planetary theory | journal=Journal for the History of Astronomy |volume=28 |issue=1 |year=1997 |pages=1–12 |location=Cambridge (UK) |bibcode=1997JHA....28....1G}}</ref>
