'''{{mp|2018 VG|18}}''', met die bynaam ''Farout'', is ’n verafgeleë [[trans-Neptunus-voorwerp]]. Op ’n afstand van ~{{val|120|ul=AE}} (meer as drie keer dié van [[Pluto]] van die [[Son]] af en byna twee keer die gemiddelde afstand van [[Eris (dwergplaneet)|Eris]]), is dit tans (Desember 2018) die verste voorwerp in die [[Sonnestelsel]] wat nog waargeneem is (die vorige verste voorwerp was Eris). Dit is sover bekend die enigste voorwerp verder as {{val|100|u=AE}} van die Son af, vandaar die bynaam.<ref name="NYT-20181217">{{cite news |last=Chang |first=Kenneth |title=It’s the Solar System’s Most Distant Object.

Dit is egter nie naastenby die voorwerp met die grootste gemiddelde wentelbaan nie, want sy [[Ellips|semihoofas]] is na raming sowat 95,2&nbsp;AE (in vergelyking hiermee is die semihoofas van {{mp|2014 FE|72}} sowat 1&nbsp;550&nbsp;AE).

Sheppard, David Tholen en Chad Trujillo het {{mp|2018 VG|18}} ontdek terwyl hulle op soek was na die hipotetiese [[Planeet Nege]].<ref name="Carnegie_2018_1217">{{cite web |title=Discovered: The Most-Distant Solar System Object Ever Observed |url=https://carnegiescience.edu/news/discovered-most-distant-solar-system-object-ever-observed |publisher=Carnegie Science |access-date=17 Desember 2018 |language=en |archive-url=https://web.archive.org/web/20191031015002/https://carnegiescience.edu/news/discovered-most-distant-solar-system-object-ever-observed |archive-date=31 Oktober 2019 |url-status=live |df=dmy-all}}</ref>
