Palibe amene wakhala akudabwitsidwa kale ndi nyenyezi ziwiri. Palinso mapulaneti pansi kapena atatu dzuwa. Komabe, machitidwe kuphatikiza nyenyezi zisanu ndi chimodzi amakhala osowa. Mpaka posachedwa, zinthu zotere zokha zadziwika, ndipo tic 168789840 zakhala 18. Izi zikunenedwa munkhani yatsopanowa omwe akatswiri a sayansi zakuthambo adalandira buku lokhudza zakuthambo la zakuthambo komanso lotsika mtengo m'chipinda cha Arxiv cha ku Arxiv.
Tic 168789840 ili mu gulu la nyenyezi la Eridan, patali kwambiri la zaka 1428. Zimaphatikizaponso awiriawiri okhudzana ndi nyenyezi, awiri omwe (a ndi c) amapanga "Kernel" ya kachitidwe, ndipo yachitatu (c) imazungulira mozungulira. Nyenyezi za dongosolo lonselo ndikudutsa wina ndi masiku 1.6, kachitidwe ka kasanu ndi 1.3, komanso 8.2. Nawonso, machitidwe okha a a ndi C amachitirana pafupifupi zaka zinayi, ndipo polonjeza dongosolo lawo zaka 2000.
NASA Astropphysiscist Brian Powell ndi ogwira nawo ntchito adapeza Tafe 168789840 mothandizidwa ndi nyenyezi zodziwika bwino ndi nyenyezi zisanu ndi chimodzi - Capor (α amapasa). Komabe, awiriawiri a Tic 168789840 ali ofanana kwambiri wina ndi mnzake: onse amaphatikizapo nyenyezi yayikulu ndi radius wa 1.2-1.3 Solar, komanso mnzake. ndi 0.5-0.6 radius kuchokera ku dzuwa.
Nyenyezi ziwiri a ndi c ali oyandikana kwambiri wina ndi mnzake, ndikupanga atsogoleri olimba kwambiri, chifukwa chake ndikosatheka kuganiza kuti mapulaneti atha kukhazikitsidwa ndikupulumuka. Komabe, asayansi amati dongosololi kukhala lokhala ndi iwo padziko lapansi. Olembawo akufuna kupitiliza zowona za tac 168789840 ndipo, mwina, kuti adziwe dziko lakutali chotere.
Ntchitoyi ipangitsa kuti zitheke momwe machitidwe achilendo amapangidwira, kuphatikizapo nyenyezi zambiri nthawi yomweyo. Amaganiziridwa kuti amatha kuwoneka ngati nyenyezi zitatu zimapangidwa limodzi - munthawi yonse ya "." Komabe, kupitirira pamtambo wogwidwa ndi mtanda, aliyense mwa dongosololo amatenga mnansi watsopano, kukhala kawiri. "Zonsezi ndizodabwitsa," akutero Brian Powell. "Ndikulakalaka ndikadakhala ndi nyenyezi, kuti ndimupatse pakeni pafupi ndi kuwona zonse ndi maso anga."
