Abstract

In this paper, we investigate the orbital behavior of the transition between the quasisatellite (QS) and horseshoe (HS) motions of 2016 HO₃. Based on the phase space structure in the Sun–Earth circular restricted three-body problem, we find that the surface of 2016 HO₃ in the torus space is a compound surface formed by QS and HS portions. Its co-orbital motion is therefore a QS–HS transition. 2016 HO₃ is currently located in a QS state, and its locus clings to the QS portion in the isosurface in agreement with the semi-analytical results. We provide a criterion to separate the QS and HS stages in the transition and obtain accurate incoming and outgoing epochs of the QS motion. We then propose an approximate curve to describe the locus of 2016 HO₃ in the ω − e projection. Virtual asteroids (VAs) near 2016 HO₃ in the isosurface were created to study the influence of the initial state of the QS–HS transition. We find that the duration of the QS state is mainly influenced by the loci in the ω − e projection. The VAs with large QS durations usually have longer loci across the QS region than those with shorter durations. In addition, although some VAs are close to 2016 HO₃ in the ω − e projection, their co-orbital behaviors are significantly different from that of the latter. This indicates that the QS–HS transition of 2016 HO₃ is sensitive to the (ω, e) position.

2016年HO3的共轨道跃迁

本文研究了2016年HO3准卫星(QS)和马蹄铁(HS)运动之间的轨道跃迁行为。基于日地圆受限三体问题的相空间结构，发现2016年HO3环面空间表面是由QS和HS两部分组成的复合表面。因此，它的共轨道运动是一个QS-HS跃迁。2016 HO3目前处于QS状态，其轨迹与半解析结果一致，依附于等值面上的QS部分。我们提供了一种准则来分离过渡阶段的QS和HS阶段，并获得了精确的QS运动的输入和输出时代。然后，我们提出了一条近似曲线来描述ω−e投影中2016年HO3的轨迹。在等值面上创建2016年HO3附近的虚拟小行星(Virtual asteroids, VAs)，研究QS-HS转变初始状态的影响。我们发现QS状态的持续时间主要受ω−e投影中的位点的影响。与持续时间较短的VAs相比，持续时间较长的VAs通常在整个QS区域具有较长的位点。此外，虽然部分VAs在ω−e投影上接近2016 HO3，但它们的共轨行为与后者有显著差异。这说明2016年HO3的QS-HS转变对(ω， e)位置很敏感。
