Query: Asteroid (469219) 2016 HO3, the smallest and closest Earth
  quasi-satellite   A number of Earth co-orbital asteroids experience repeated transitions
between the quasi-satellite and horseshoe dynamical states. Asteroids 2001 GO2,
2002 AA29, 2003 YN107 and 2015 SO2 are well-documented cases of such a
dynamical behaviour. These transitions depend on the gravitational influence of
other planets, owing to the overlapping of a multiplicity of secular
resonances. Here, we show that the recently discovered asteroid (469219) 2016
HO3 is a quasi-satellite of our planet -the fifth one, joining the ranks of
(164207) 2004 GU9, (277810) 2006 FV35, 2013 LX28 and 2014 OL339. This new Earth
co-orbital also switches repeatedly between the quasi-satellite and horseshoe
configurations. Its current quasi-satellite episode started nearly 100 yr ago
and it will end in about 300 yr from now. The orbital solution currently
available for this object is very robust and our full N-body calculations show
that it may be a long-term companion (time-scale of Myr) to our planet. Among
the known Earth quasi-satellites, it is the closest to our planet and as such,
a potentially accessible target for future in situ study. Due to its presumably
lengthy dynamical relationship with the Earth and given the fact that at
present and for many decades this transient object remains well positioned with
respect to our planet, the results of spectroscopic studies of this small body,
26-115 m, may be particularly useful to improve our understanding of the
origins -local or captured- of Earth's co-orbital asteroid population. The
non-negligible effect of the uncertainty in the value of the mass of Jupiter on
the stability of this type of co-orbitals is also briefly explored.
