Isifinyezo semicimbi yezinkanyezi yonyaka we-2018

Unyaka ka-2018 uqale isonto nezinsuku ezimbili ezedlule futhi ulayishwe ngawo imicimbi ehlukene yezinkanyezi ongeke wakulahleka. Ukusuka ezinkanyezini eziwayo kuya ekusithekeni.

Ngabe ufuna ukwazi ukuthi iziphi izenzakalo ezisilindele unyaka wonke?

Imicimbi ehlobene nenyanga

Indawo esondele kakhulu yeNyanga eMhlabeni ibizwa ngokuthi i-perigee. Kulo Januwari 2 odlule, inyanga yayisePerigee. Ngokunikwa ukuthi inyanga ithini, sizokwazi ukujabulela enye inyanga egcwele phakathi nenyanga kaJanuwari 31. Lo mcimbi ongenzeki kaningi ubizwa I-Blue Moon, yize umbala ungabonwa. Ngaphezu kwalokho, kuzokwenzeka ukufiphala kwenyanga okuphelele, kodwa ngeke kubonakale eSpain. Uma ufuna ukubona lesi simo kufanele uye eNyakatho Melika nase-Australia.

Okunye ukusitheka okuphelele kwenyanga kungajatshulelwa ngoJulayi 27 futhi kuzoheha ukwedlula eyedlule, ngoba iNyanga ingabonakala ngethoni ebomvu. Lokhu kusitheka kwelanga kungabonakala eSpain futhi indawo enhle kakhulu izoba seziQhingi zeBalearic, lapho kutholakala khona ukufiphala okukhulu ngo-22: 21 ebusuku (isikhathi senhlonipho).

Imicimbi ehlobene neLanga

• NgoJanuwari 3, uMhlaba wabekwa endaweni esondele kakhulu maqondana neLanga, wabeka ngamakhilomitha ayizigidi eziyi-147 kuphela.
• NgoFebhuwari 15, kuzokwenzeka ukusitheka kwelanga okuyingxenye, yize kungeke kubonakale eSpain. Izobonakala kuphela e-Antarctica naseNingizimu Melika.
• NgoJulayi 6, uMhlaba uzobe usendaweni ekude kakhulu neLanga Amakhilomitha ayizigidi eziyi-152.

Imicimbi yenkanyezi

Imicimbi ye-meteor shower ihlukaniswe kabili: ebuthakathaka futhi enamandla kunayo yonke. Ake siqale sibheke ukuhlanganiswa kwemicimbi yezinkanyezi zokudubula okungapheli kanye nosuku ezizokwenzeka ngalo.

Ukuwa okuntekenteke okuntenga

• NgoFebhuwari sizoba nemicimbi emibili yama-meteor shower esaziwa ngokuthi i-alpha-centáurides ne-delta-leonids. Owokuqala uzokuba ngoFebhuwari 8 bese kuthi owesibili ube ngo-24.
• NgoMashi singajabulela ezinye izimvula ezincane ezibiziwe IGamma-Normids neVirginids. Zizokwenzeka ngomhla ka-13 no-25, ngokulandelana.

• U-Okthoba ubuye abe nezinye izihlambi zemeteor ezibuthakathaka ezaziwa njenge amadraconids (Okthoba 8), li-ace epsilon-geminids (Okthoba 18) nama-orionids (Okthoba 21).
• UNovemba unamatshe amane abuthakathaka iMeteor Showers asabalala inyanga yonke. Baziwa ngokuthi ama-taurid aseningizimu, ama-taurid asenyakatho, ama-leonid kanye ne-alpha-monocerotids. Zizokwenzeka ngezinsuku 5, 12, 17 no-21, ngokulandelana.

Izinkanyezi eziwa ngamandla

Imibukiso emithathu yamameteor edume kakhulu izokwenzeka unyaka wonke. Le micimbi ingagcizelelwa kakhulu futhi yaziwe kubalandeli abaningi bezinkanyezi (nalabo abangekho). Le micimbi yile:

• Ama-eta aquarids. Ziyaziwa ukuthi zihlotshaniswa ne-Halley's Comet. Kuyishawa semeteor ngomsebenzi we 60 meteors ngehora futhi ingabukwa ngoMeyi 6.

Ngalolu lwazi, awunasizathu sokuphuthelwa yiyo yonke imicimbi yezinkanyezi ezokwenzeka kulo nyaka. Zijabulele!
