chilengedwe chathu ndi waukulu, ndipo zikuoneka kuti ife kuti zambiri za dziko palibe, koma izo siziri. Pali dziko kwakukulu bulkier. Pakuti chilengedwe chonse, dziko lathu - monga njere ya mchenga anataya izo. Dongosolo dzuwa chinthu chimodzi chokha mu mlalang'ambawu. Dzuwa - ndi chigawo chachikulu cha mlalang'ambawu. Eyiti mapulaneti chinali dzuwa. Izo zinali kokha chinayi - Pluto - chifukwa chakuti mphamvu yokoka ndi misa chimaonekera mndandanda wa mapulaneti onsewo. Aliyense dziko magawo ake, osalimba, kutentha. Pali anthu amene wapangidwa mpweya, pali chimphona, waung'ono, ozizira, wotentha, nyenyezi yaing'ono.
Kotero dziko waukulu kudziwika pa mphindi? Mu April 2006, chinthu chimene chinagwedeza chiphunzitso cha zakuthambo. The Lowell Observatory (USA, Arizona) ndi dziko yaikulu owonjezera nthawi makumi awiri kukula kwa Dziko lathu, anatulukira mu kuwundana Hercules. A alipo lotseguka lero - ndi dziko lalikulu kwambiri m'chilengedwe chonse. Ndi red-hot ndipo ndi ofanana ndi Dzuwa, komabe dziko a. Iye ankatchedwa Tres-4. kukula kwake kuposa kukula kwa dziko waukulu mu dongosolo la zowalitsa - Jupiter - mu nthawi 1,7. Ndi chimphona mpira mpweya. Tres-4 Amakhala makamaka a haidrojini. Dziko waukulu makina nyenyezi imene ili pa mtunda wa 1400 zaka kuwala. zinthu Kutentha pamwamba pake ndi madigiri zoposa 1260.
Pali okwanira Mapulaneti akuluakulu, koma ndigwira sanatsegule kuposa Tres-4b. Dziko yaikulu ndi lalikulu kuposa Jupiter ndi oposa 70%. A yaikulu mpweya chimphona angatchedwe nyenyezi, koma kasinthasintha ake mozungulira nyenyezi yake GSC02620-00648 anafotokoza izo motsimikiza kuti mapulaneti zakuthambo. Malinga ndi antchito udindo wa Observatory G. Mandushev, gaseous dziko kuposa olimba, ndipo n'zotheka pokhapokha madzi. kachulukidwe ake ranges ku magalamu 0.2 pa centimeter kiyubiki, amene angafanane ndi balsa (Nkhata Bay) mtengo. Asayansi asayansi ankati N'chifukwa chiyani dziko yaikulu ndi machulukidwe ngati otsika amatha kulibe. Planet Tres-4 amatchedwanso Tres-4b. Kupezeka wake wa izo mosakayikira zakuthambo ankachita masewera amene anapeza Tres-4, ndi zopezera wa telesikopu yaing'ono yodzichitira ili Canary Islands ndi boma la Arizona.
Ngati musunga dzikoli kuchokera pansi, zikuonekeratu kuti ikuyenda kudutsa pang'ono nyenyezi ake. Amatanthauza exoplanet mozungulira nyenyezi mu masiku 3,55 chabe. Planet Tres-4 poyerekeza ndi dzuwa ndi wambiri kuposa ali apamwamba kutentha.
Apainiyawo ndodo Lowell ndi zakuthambo kenako University Harvard ndi WM Keck Observatory Hawaii kuti anatsimikizira kafukufukuyu. Pa Lowell Observatory asayansi amanena kuti waukulu dziko Tres-4 - osati kuwundana izi, ndipo zikuoneka mu kuwundana ndi Hercules kungakhale kudziko lina. Wogwila Lowell mu 1930, dziko anapeza dziko laling'ono mu dongosolo la zowalitsa - Pluto. Koma mu 2006, Pluto, poyerekeza ndi chimphona Tres-4, anayamba kutchedwa dziko nyenyezi yaing'ono.
