Originally 2004 DW, the largest Plutino after Pluto. Thought of as the "anti-Pluto" because it is at perihelion when Pluto is at aphelion and vice versa. It also has a similarly large in ratio moon. Named after Pluto's Etruscan equivalent, while its moon is named after the one who ferried souls to the underworld, Vanth. It was the thought to be the largest TNO at discovery (after Quaoar), and now thought to be almost certainly a dwarf planet by Mike Brown.
