Akekho osemude emangaza kabili futhi ngisho no-Triple Star Systems; Kukhona namaplanethi angaphansi kwamalanga amabili noma amathathu. Kodwa-ke, izinhlelo ezibandakanya izinkanyezi eziyisithupha zihlale zingajwayelekile. Kuze kube muva nje, kuphela izinto ezinjalo ezinjalo ezaziwaziwayo, futhi tic 168789840 ziye zaba yi-18. Lokhu kubikwa ukuthi ku-athikili entsha ngezazi zezinkanyezi zaseMelika zamukele ukushicilelwa ejereli yezinkanyezi futhi ezingabizi kulabhulali evulekile ye-inthanethi.
I-Tic 168789840 itholakala kwi-Constellation Eridan, ebangeni leminyaka engu-1428. Kubandakanya ngazimbili ezihlobene nezinkanyezi, ezimbili zazo (a no c) zakha i- "kernel" yohlelo, kanti lwesithathu (c) lijikeleza nxazonke ngakusasa. Izinkanyezi zohlelo oluphindwe kabili futhi zidlula komunye nomunye ngezinsuku eziyi-1,6, uhlelo C - ngezinsuku eziyi-1,3, naku-8.2. Futhi, amasistimu ngokwawo a futhi c aphathana cishe iminyaka emine emhlabeni, futhi ngokudlula uhlelo lwawo eminyakeni engama-2000.
I-NASA Astrophysicist Brian Powell nozakwabo bathola iTic 168789840 ngosizo lwe-TSS Outer Telsescope, baphawula ukuthi isakhiwo esinjalo sifana nenkanyezi eminingi eyaziwayo enezakhi eziyisithupha - ama-castor (amawele we-castor (amawele). Kodwa-ke, ngazimbili ezintathu ze-TIC 168789840 zifana kakhulu nomunye: zonke zifaka inkanyezi enkulu ngerediyo ye-1.4-1.7 yelanga, kanye nomlingani wayo omncane, kanye nomngane wakhe omncane onesisindo esingu-0.5 -07 solar kanye 0.5-0.6 Radius kusuka elanga.
Izinkanyezi eziphindwe kabili A no-C zisondelene kakhulu komunye nomunye, zidala ukungafani namehlo eziqinile, ngakho-ke akunakwenzeka ukuthi zicabange ukuthi amaplanethi angakhiwa futhi aphile. Kodwa-ke, ososayensi bathi uhlelo olukude kakhulu nalo emhlabeni lungase lube khona. Ababhali bahlela ukuqhubeka nokubonwa kwe-Tic 168789840 futhi, mhlawumbe, ukuthola izwe elikude elinjalo.
Lo msebenzi uzokwenza kube nokwenzeka ukuthola ukuthi izinhlelo ezingavamile zakhiwa kanjani, kufaka phakathi izinkanyezi eziningi ngokushesha. Kucatshangwa ukuthi zingavela njengoba izinkanyezi ezintathu zakhiwa ndawonye - endaweni ethi "Cradle." Kodwa-ke, phambili, edlula efwini eliphethwe ngegesi, ngamunye wabahlanganyeli bohlelo wathola umakhelwane omusha, waba kabili. UBrian Powell uthi: "Konke lokhu kuyamangaza. "Ngifisa sengathi ngabe ngibe nenkanyezi, ngimpake eduze futhi ngibone bonke ngamehlo ami."
