FarFarOut
FarFarOut is the nickname of a trans-Neptunian object discovered well beyond from the Sun. Imaged in January 2018 during a search for the hypothetical Planet Nine, the object was announced in a press release on February 21, 2019, by astronomers Scott Sheppard, David Tholen, and Chad Trujillo, when they nicknamed it "FarFarOut" to emphasize its distance from the Sun.Distance
The object was initially estimated to be roughly from the Sun. But with a very short observation arc the uncertainties in this estimated distance have not been published., it is the furthest observed member of the Solar System.
Many near-parabolic comets are much further from the Sun. Caesar's Comet is calculated to be more than from the Sun. Comet Donati is from the Sun.
