2012 FC71, also written 2012 FC71, is a small asteroid trapped in a Kozai resonance with the Earth.
As of 21 April 2012 its orbit is based on 35 observations spanning a data-arc of 21 days.
It will remain both very dim (around apparent magnitude 27), and close in the sky to the Sun (solar elongation of less than 90 degrees), making it impossible to observe with current ground based telescopes till the 2060s.
[2] 2012 FC71 is locked in a Kozai resonance and as such it has a very slow orbital evolution and it will remain relatively unperturbed for hundreds of thousands of years.
It may have been originated within the Venus-Earth-Mars region or in the main asteroid belt like other Near-Earth Objects, then transitioned to an Amor-class asteroid before entering Earth's co-orbital region.
