Query: The role of the Yarkovsky effect in the long-term dynamics of asteroid
  (469219) Kamo'oalewa   Near-Earth asteroid (469219) Kamo'oalewa (aka 2016 HO3) is an Earth
co-orbital and a potential space mission target. Its short-term dynamics is
characterized by a periodic switching between quasi-satellite and horseshoe
configurations. Due to its small diameter of only about 36 meters, the
Yarkovsky effect may play a significant role in the long-term dynamics. In this
work, we addressed this issue by studying the changes in the long-term motion
of Kamo'oalewa caused by the Yarkovsky effect. We used an estimation of the
magnitude of the Yarkovsky effect assuming different surface compositions and
introduced the semi-major axis drift by propagating orbits of test particles
representing the clones of the nominal orbit. Our simulations showed that the
Yarkovsky effect may cause Kamo'oalewa to exit from the Earth co-orbital region
a bit faster when compared to a purely gravitational model. Nevertheless, it
still could remain an Earth companion for at least 0.5 My in the future. Our
results imply that Kamo'oalewa is the most stable Earth's co-orbital object
known so far, not only from a short-term perspective but also on long time
scales.
