Abstract
General relativity effects coupled with those derived from the von Zeipel–Lidov–Kozai mechanism may play a significant role on the evolution of members of the Atira dynamical class, particularly in the case of those with the shortest sidereal orbital periods. Here, we provide a preliminary assessment of the short-term orbital evolution of 2021 PH27, a recently discovered Atira that has the shortest period among known asteroids. Our calculations, based on a publicly available orbit determination and including post-Newtonian terms in the numerical integrations, show that 2021 PH27 is a robust member of the Atira class and it may indeed be used to explore the combined effects of general relativity and the von Zeipel–Lidov–Kozai mechanism once its orbit determination is sufficiently improved.
