(119979) 2002 WC19, also written as (119979) 2002 WC19, is a twotino, i.e. it is in a 1:2 orbital resonance with Neptune. It was discovered on November 16, 2002 at the Palomar Observatory. It is probably a dwarf planet.
Knowing how many twotinos there are may reveal whether Neptune took roughly 1 million or 10 million years to migrate about 7 AU from its birth location.
