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…

A newly discovered asteroid 2016 HO3 has coorbital type of retrograde (or quasi) satellite with respect to Earth. The discovery enlarges number of known retrograde satellites of Earth. In this work

The orbital dynamics of asteroid 469219 Kamo’oalewa

The study of orbital dynamics and evolution of Solar system small-bodies like asteroids has been conducted regularly with the latest data to ensure and update our understanding of the object’s

Geophysical and orbital environments of asteroid 469219 2016 HO3

Asteroid 469219 Kamo’oalewa, also named 2016 HO3, is a small-size fast-rotating near-Earth asteroid, which is a potential target for future explorations. Owing to its weak gravity and fast spin rate,

Lunar-like silicate material forms the Earth quasi-satellite (469219) 2016 HO3 Kamoʻoalewa

Little is known about Earth quasi-satellites, a class of near-Earth small solar system bodies that orbit the sun but remain close to the Earth, because they are faint and difficult to observe. Here

On the orbital evolution of meteoroid 2020 CD3, a temporarily captured orbiter of the Earth–Moon system

Any near-Earth object (NEO) following an Earth-like orbit may eventually be captured by Earth's gravity during low-velocity encounters. This theoretical possibility was first attested during the

Simulation of global GM estimate of Asteroid (469219) 2016 HO3 for China's future asteroid mission

Asteroid (469219) 2016HO3 (hereinafter called HO3) is the most stable (known) quasi-satellite of Earth. China plans to launch a sample return mission to this target, called Zhenghe, consisting of an

Asteroid 2017 FZ2 et al.: signs of recent mass-shedding from YORP?

The first direct detection of the asteroidal YORP effect, a phenomenon that changes the spin states of small bodies due to thermal reemission of sunlight from their surfaces, was obtained for (54509)

Horseshoe co-orbitals of Earth: current population and new candidates

Most co-orbital objects in the Solar system are thought to follow tadpole-type orbits, behaving as Trojans. However, most of Earth's identified co-orbitals are moving along horseshoe-type orbits. The

The analemma criterion: accidental quasi-satellites are indeed true quasi-satellites

In the Solar system, a quasi-satellite is an object that follows a heliocentric path with an orbital period that matches almost exactly with that of a host body (planetary or not). The trajectory is
