2017 OF201

{{DISPLAYTITLE:2017 OF201}}
I-2017 OF201 yinto egqithileyo ye-Neptunian kunye nomviwa weplanethi encinci, eqikelelwa ubuncinane kwiikhilomitha ezingama-550 (iimayile ezingama-340) ububanzi. Ngobukhulu obupheleleyo obuphakathi kwe-3 kunye ne-4, inokuba yeyona nto iqaqambileyo eyaziwayo kwiSolar System engenalo ubungakanani obuqikelelweyo ngokuthe ngqo. I-perihelion yayo yokugqibela yayimalunga noNovemba 1930. Ukusukela ngo-2025, umgama wayo ngoku ukusuka eLangeni yi-90.5 AU, nto leyo eyenza ibe yenye yezona zinto zikude zeSolar System ezijongweyo.

Ukufunyaniswa kwe 2017 OF201 kunokugqiba ukuphikisa ubukho bePlanethi yeThoba kwaye, mhlawumbi, iiplanethi ezingaphaya kweNeptune ngokubanzi. Ukuqhelaniswa nemijikelo yezinto ezigqithileyo zeNeptunian zithande ukuhlangana. Oku kuhlanganisana kukhokelela kwingcinga yokuba iplanethi enokubakho ekude ibe nefuthe kwezo ndlela zijikelezayo. Nangona kunjalo, i-orbit ye 2017 OF201 yenye yezona zimbalwa [ezifana ne 2013 FT28 kunye 2015 KG163] echasene nokulungelelaniswa kwi-orbit ebalwayo yePlanethi yeThoba. Ukwenza imodeli kucebisa ukuba iplanethi ecingelwayo ngeyikhuphe i-2017 OF201 kwi-orbit yayo yangoku ngamaxesha esikali esingaphantsi kwe-100 lezigidi zeminyaka, nangona inokuba kwi-orbit yethutyana.

 I-Orbit 
I-2017 OF201 ijikeleza kude ngaphaya kweNeptune kumgama ophakathi kwama-880 eeyunithi zeenkwenkwezi (AU), ithatha iminyaka engama-25,000 ukugqiba i-orbit ejikeleze iLanga. I-2017 OF201 ine-orbit ene-orbital eccentricity ye-0.95 kunye ne-orbital inclination ye-16.21 °. I-2017 OF201 inenye yezona zinto zikude kakhulu ze-aphelia eyaziwayo ye-trans-Neptunian, efana ne-2013 SY99 kwaye yodlulwa ngo-2019 EU5, zonke ezintathu zineperihelia ngaphakathi kwe-Kuiper cliff kwaye ziye okanye zinentsebenziswano neNeptune. Oku kubeka le nto kufuphi nomda oqikelelweyo wengingqi yediski esasazekileyo kunye neengcinga ezithile zefu elingaphakathi le-Oort. I-orbit ka-2017 OF201 ibunjwe zizo zombini iNeptune kunye ne-galactic tide kwiibhiliyoni zeminyaka.

 Iimpawu zomzimba 
Idayamitha ka-2017 OF201 ayaziwa, kodwa kuqikelelwa ukuba iphakathi kwe-550-850 yeekhilomitha ububanzi, ibeka phakathi koluhlu lweeplanethi ezincinci ezinokwenzeka. Ukufumana ireferensi, iPluto yi-2,376.6 yeekhilomitha ububanzi, kwaye iQuaoar, eyamkelwa ngokubanzi njengeplanethi encinci, yi-1,090 yeekhilomitha ububanzi."An Extreme Cousin for Pluto?
