Yintoni inyanga enkulu?Zenza njani iisupermoons?

Inyanga enkulu (iSupermoon) ligama elicetywe sisazi ngeenkwenkwezi saseMelika uRichard Noelle ngo-1979. Yinto eyenzekayo apho inyanga ikufuphi neperigee xa inyanga isentsha okanye izele.Xa inyanga ikwi-perigee, kuvela inyanga entsha, ebizwa ngokuba yinyanga eNtsha enkulu;Inyanga igcwele kanye xa ikwi-perigee, eyaziwa ngokuba yinyanga egcweleyo.Ngenxa yokuba inyanga ijikeleza umhlaba kungqameko oluyingqukuva, umgama ophakathi kwenyanga nomhlaba uhlala utshintsha, ngoko okukhona inyanga isondela emhlabeni xa inyanga epheleleyo ifika, kokukhona kuya kubonakala ukuba nkulu kwenyanga epheleleyo.
Iingcali zenzululwazi ngeenkwenkwezi zazisa ukuba “inyanga enkulu” iya kuvela esibhakabhakeni ebusuku ngoJuni 14 (ngoMeyi 16 wekhalenda yenyanga), ekwayiyo “inyanga egcweleyo yesibini” kulo nyaka.Ngelo xesha, ukuba nje imozulu ilungile, uluntu oluvela kulo lonke ilizwe lethu lunokonwabela umjikelo wenyanga enkulu, njengepleyiti entle yejeyidi ejinga phezulu esibhakabhakeni.
Xa inyanga nelanga zimacala omabini omhlaba, kwaye i-ecliptic longitude yenyanga nelanga ihluke ngama-degrees angama-180, inyanga ebonwa emhlabeni yeyona nto ingqukuva, ebizwa ngokuba “yinyanga epheleleyo”, eyaziwa nangokuthi “inyanga epheleleyo”. njenge "jonga".Ishumi elinesine, leshumi elinesihlanu, leshumi elinesithandathu kunye neshumi elinesixhenxe kwinyanga nganye yenyanga ngamaxesha apho inyanga epheleleyo ingabonakala.
Ngokutsho kukaXiu Lipeng, ilungu leChinese Astronomical Society nomalathisi weTianjin Astronomical Society, umjikelo wenyanga ojikeleza umhlaba “uthe tyaba” ngakumbi kunomjikelo ojikelezayo womhlaba ojikeleze ilanga.Ukongeza, inyanga isondele kakhulu emhlabeni, ngoko inyanga ikwi-perigee Ibonakala inkulu kancinci xa ikufuphi kunaxa ikufuphi ne-apogee.
Kunyaka wekhalenda, kukho iinyanga ezili-12 okanye ezili-13 ezipheleleyo.Ukuba inyanga epheleleyo isondele kwi-perigee, inyanga iya kubonakala inkulu kwaye ijikeleze ngeli xesha, ebizwa ngokuba yi "supermoon" okanye "inyanga egcweleyo".“Iinyanga ezinkulu” aziqhelekanga, ukususela kanye okanye kabini ngonyaka ukusa kwizihlandlo ezithathu okanye ezine ngonyaka.“Eyona nyanga izeleyo inkulu” yonyaka ibakho xa inyanga epheleleyo isondele kakhulu kwixesha apho inyanga ikwi-perigee.
Inyanga epheleleyo eyavela ngoJuni 14, umzuzu ogcweleyo wabonakala ngo-19:52, ngelixa inyanga yayi-perigee kakhulu ngo-7:23 ngoJuni 15, ixesha elijikelezayo kunye nexesha le-perigee lalingaphantsi kweeyure ezili-12 kuphela, Idayamitha ebonakalayo yobuso benyanga yale nyanga igcweleyo inkulu kakhulu, ephantse ifane “neyona nyanga ipheleleyo” yalo nyaka.“Eyona nyanga inkulu izeleyo” yalo nyaka ivela ngoJulayi 14 (usuku lweshumi elinesithandathu lwenyanga yesithandathu).
“Emva kokuhlwa komhla we-14, amalungu anomdla oluntu asuka kulo lonke ilizwe lethu anokunikela ingqalelo kule nyanga inkulu esesibhakabhakeni ebusuku kwaye ayonwabele ngeliso lenyama ngaphandle kokufuna nasiphi na isixhobo.U-Xiu Lipeng uthe, “Lo nyaka 'ubuncinane benyanga epheleleyo' kwenzeke ngoJanuwari walo nyaka.Ngomhla we-18, ukuba umntu onenjongo yokufota inyanga epheleleyo ngelo xesha, wayenokusebenzisa kwaezo zixhobo kwaneeparamitha zobude obufanayo ukuze afote kwakhona xa inyanga ikwindawo enye ethe tye.'Inkulu' kangakanani inyanga enkulu egcweleyo.”
