Tianwen-2 target asteroid (469219) Kamo'oalewa probably develops an Itokawa-compositional but ultra-highly space-weathered surface
Pengfei Zhang, Guozheng Zhang, Zichen Wei +45
China's Tianwen-2 mission plans to return samples from a small, rapidly spinning Earth quasi-satellite (469219) Kamo'oalewa. Previous studies linked Kamo'oalewa to lunar compositio…
Dynamical Origin of (469219) Kamo`oalewa of Tianwen-2 Mission from the Main-Belt: Secular Resonance, Flora Family or 3:1 Resonance with Jupiter
Yandong Wang, Shoucun Hu, Jianghui Ji +1
China's Tianwen-2 mission, launched on 29 May 2025, targets the near-Earth object (469219) Kamo`oalewa, an Earth quasi-satellite trapped in a 1:1 mean-motion resonance with our pla…
Classifying and characterizing the evolution of minimum orbit intersection distance for near-Earth asteroids
Shoucun Hu, Yuanyuan Chen, Xinran Li +2
In this paper, the minimum orbit intersection distances (MOIDs) of near-Earth asteroids (NEAs) over the next 200 years were computed and analyzed in detail. It was shown that the M…
PyMsOfa: A Python Package for the Standards of Fundamental Astronomy (SOFA) Service
Jianghui Ji, Dongjie Tan, Chunhui Bao +4
The Standards of Fundamental Astronomy (SOFA) is a service provided by the International Astronomical Union (IAU) that offers algorithms and software for astronomical calculations,…
Peculiar orbital characteristics of Earth quasi-satellite 469219 Kamo`oalewa: implications for the Yarkovsky detection and orbital uncertainty propagation
Shoucun Hu, Bin Li, Haoxuan Jiang +2
469219 Kamo`oalewa is selected as one of the primary targets of Tianwen-2 mission, which is currently believed to be the most stable quasi-satellite of Earth. Here we derive a weak…
Mid-IR Observations of IRAS, AKARI, WISE/NEOWISE and Subaru for Large Icy Asteroid (704) Interamnia: a New Perspective of Regolith Properties and Water Ice Fraction
Haoxuan Jiang, Jianghui Ji, Liangliang Yu +3
(704) Interamnia is one of the largest asteroids that locates in the outer main-belt region, which may contain a large amount of water ice underneath its surface. We observe this a…
Orbital effects on time delay interferometry for TianQin
Ming-Yue Zhou, Xin-Chun Hu, Bobing Ye +5
The proposed space-borne laser interferometric gravitational wave (GW) observatory TianQin adopts a geocentric orbit for its nearly equilateral triangular constellation formed by t…
Sublimation as an effective mechanism for flattened lobes of (486958) Arrokoth
Yuhui Zhao, Ladislav Rezac, Yuri Skorov +3
The New Horizons spacecraft's flyby of Kuiper Belt Object (KBO) (486958) Arrokoth revealed a bilobed shape with highly flattened lobes both aligned to its equatorial plane, and a r…
Critical spin periods of sub-km-sized cohesive rubble-pile asteroids: dependencies on material parameters
Shoucun Hu, Derek C. Richardson, Yun Zhang +1
In this work, we employ a soft-sphere discrete element method with a cohesion implementation to model the dynamical process of sub-km-sized cohesive rubble piles under continuous s…
The formation mechanism of 4179 Toutatis' elongated bi-lobed structure in a close Earth encounter scenario
Shoucun Hu, Jianghui Ji, Derek C. Richardson +2
The optical images of near-Earth asteroid 4179 Toutatis acquired by Chang'e-2 spacecraft show that Toutatis has an elongated contact binary configuration, with the contact point lo…
Fundamentals of the orbit and response for TianQin
Xin-Chun Hu, Xiao-Hong Li, Yan Wang +6
TianQin is a space-based laser interferometric gravitational wave detector aimed at detecting gravitational waves at low frequencies (0.1 mHz -- 1 Hz). It is formed by three identi…
Using Chebyshev polynomials interpolation to improve the computation efficiency of gravity near an irregular-shaped asteroid
Shoucun Hu, Jianghui Ji
In asteroid rendezvous missions, the dynamical environment near the asteroid's surface should be made clear prior to the mission launch. However, most of the asteroids have irregul…
TianQin: a space-borne gravitational wave detector
Jun Luo, Li-Sheng Chen, Hui-Zong Duan +17
TianQin is a proposal for a space-borne detector of gravitational waves in the millihertz frequencies. The experiment relies on a constellation of three drag-free spacecraft orbiti…
Revisit of rotational dynamics of Asteroid 4179 Toutatis from Chang'e-2's flyby
