'''{{mp|2014 FE|72}}'''是一個位於[[離散盤]]內的[[海王星外天體]]，其軌道深入內[[奥尔特云]]<ref name = " MPEC 2016-Q43" />。該天體由[[斯科特·谢泼德]]與[[乍德·特魯希略]]發現，並於2016年8月29日公開<ref name = " MPEC 2016-Q43" /><ref name = "Carnegie2016-08-29" />。

==軌道==
2014 FE72的軌道是[[軌道離心率]]高達0.98的橢圓軌道，因此[[近日點]]約36.3天文單位，遠日點達到約3800天文單位，軌道周期約86000年<ref name="jpldata" />。它的遠日點與軌道週期分別為另一顆[[海王星外天體]][[小行星90377|賽德娜]]的4和8倍，是已知太陽系內[[長週期彗星]]以外天體中軌道週期最长者。然而，該天體已知的觀測弧很短，並且軌道離心率極高，因此前述軌道數值並非準確估計值<ref name="jpldata" />。

{{mp|2014 FE|72}}上次通過近日點是1965年，2016年8月29日宣布時距離太陽約61.4天文單位<ref name="jpldata" />。
