Indalo yethu inkulu kakhulu, futhi kubonakala sengathi akukho lutho olungaphezu kwenhlabathi , kodwa akunjalo. Kukhona amaplanethi amakhulu kakhulu futhi amaningi kakhulu. Ngokuba yonke indawo yonke, uMhlaba wethu ungumhlanhla nje wesihlabathi, olahlekelwe kuwo. I-solar system ingenye yezakhi ze-Galaxy. Ilanga yiyona ingxenye enkulu ye-Galaxy. Amaplanethi ayisishiyagalombili azungeze ilanga. Futhi kuphela okwesishiyagalolunye - i-Pluto - ngenxa yamandla ayo amakhulu nokukhulula kususwe ohlwini lwamaplanethi ajikelezayo. Iplanethi ngayinye inezilinganiso zayo, ubuningi, izinga lokushisa. Kukhona ezinye ezakhiwe negesi, zikhona ezinkulu, ezincane, ezibandayo, ezishisayo, ezinwabuzelayo.
Ngakho yiyiphi iplanethi enkulu kunazo zonke eyaziwayo okwamanje? Ngentwasahlobo ka-2006, kwenzeka umcimbi owazamazamisa inkolelo yezidalwa zasezulwini. E-Lovell Observatory (eU.SA, eArizona) e-constellation Hercules wathola iplanethi enkulu, eyedlula ubukhulu bomhlaba wethu izikhathi ezingamashumi amabili. Kokuvulekile okukhona namuhla - lena iplanethi enkulu kunazozonke endaweni yonke. Kutshisa futhi kufana ne-Sun, kodwa kusekhona iplanethi. Labizwa nge-TrES-4. Ubukhulu bayo budlula ubukhulu bezinkulu kunazo zonke ohlelweni lwelanga lomhlaba - Jupiter - izikhathi ezingu-1.7. Kuyinto ibhola elikhulu gaseous. I-TrES-4 iqukethe i-hydrogen. Iplanethi enkulu kunazo zonke yenza izinguquko ezungeze inkanyezi, etholakala eminyakeni engu- 1400 yokukhanya. Umbuso wokushisa obusweni bawo ungaphezu kuka-1260 degrees.
Kukhona inani elanele lamaplanethi amakhulu, kodwa kuze kube manje awuvuli ngaphezulu kune-TrES-4b. Iplanethi enkulu kakhulu ngobukhulu idlula i-Jupiter ngamaphesenti angu-70%. I-giant enkulu yegesi ingabizwa ngokuthi inkanyezi, kodwa ukujikeleza kwayo eduze nenkanyezi yayo i-GSC02620-00648 iyalandisa ngokuqondile emzimbeni wasezulwini. Njengoba isikhulu esiphezulu se-Observatory G.Mandushev sitshele ukuthi, iplanethi ingcono kakhulu kunokuthi iqine, futhi kungenzeka ukufaka kuwo kuphela. Ubuningi bayo buhluka kusuka ku-0.2 g ububanzi bamakhilogremu, okungafani nokhuni lwe-balsa (cork). Ososayensi-izazi zezinkanyezi zilahlekile ngokucabanga: indlela le phlanethi enkulu kunazo zonke ezinamandla kangaka enamandla okuba khona. Iplanethi i-TrES-4 ibizwa nangokuthi i-TrES-4b. Ukutholakala kwalo kubangelwa ama-astronomers amateur abathola i-TrES-4 ngokusebenzisa inethiwekhi yamabonakude amancane asebenzayo aseCanary Islands nase- Arizona.
Uma ubukela le phlanethi kusukela emhlabathini, ungabona ngokucacile ukuthi iyahamba eduze kwediski yenkanyezi yayo. I-exoplanet ihlose inkanyezi ngezinsuku ezingu-3.55 kuphela. Iplanethi i-TrES-4 iyinkimbinkimbi ngokuqhathanisa ne-Sun futhi inezinga lokushisa eliphakeme.
Abaqothule babe yiLowell, futhi kamuva izazi zezinkanyezi eHarvard University kanye neHawaiian observation WM Keck ziqinisekisile lokhu kutholakala. Ososayensi be-Lovell Observatory banombono wokuthi iplanethi enkulu kunazo zonke, i-TrES-4, akuyona yedwa kule nkanyezi, futhi kungenzeka ukuthi kunenye iplanethi ku-Hercules yezinkanyezi. Abasebenzi uLowell ngo - 1930 bavula iplanethi encane kunazo zonke emhlabeni ohlelweni lwelanga - i-Pluto. Nokho, ngo-2006, uPluto, ngokuqhathaniswa ne-giant TrES-4, waqala ukubizwa ngokuthi iplanethi engamatshe.
