The minor planet 2002 VE68 was identified as a quasi-satellite of Venus shortly after its discovery. At that time its data-arc span was only 24 d; now it is 2947 d. Here we revisit the topic of the dynamical status of this remarkable object as well as look into its dynamical past and explore its future orbital evolution which is driven by close encounters with both the Earth–Moon system and Mercury. In our calculations, we use a Hermite integration scheme, the most updated ephemerides and… 

Dynamical evolution of near-Earth asteroid 1991 VG

The discovery of 1991 VG on 1991 November 6 attracted an unprecedented amount of attention as it was the first near-Earth object (NEO) ever found on an Earth-like orbit. At that time, it was

On the orbital evolution of 2020 AV2, the first asteroid ever observed to go around the Sun inside the orbit of Venus

The innermost section of the Solar system has not been extensively studied because minor bodies moving inside Earth’s orbit tend to spend most of their sidereal orbital periods at very low solar

Asteroid 2012 XE133: a transient companion to Venus

Apart from Mercury that has no known co-orbital companions, Venus remains as the inner planet that hosts the smallest number of known co-orbitals (two): (322756) 2001 CK 32 and 2002 VE 68 . Both

Asteroid 2014 OL339: yet another Earth quasi-satellite

Our planet has one permanently bound satellite -the Moon-, a likely large number of mini-moons or transient irregular natural satellites, and three temporary natural retrograde satellites or

Asteroid (469219) 2016 HO3, the smallest and closest Earth quasi-satellite

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

(309239) 2007 RW10: a large temporary quasi-satellite of Neptune

Upon discovery, asteroid (309239) 2007 RW10 was considered a Neptune Trojan candidate. The object is currently listed by the Minor Planet Center as a Centaur but it is classified as a Scattered Disk

Asteroid 2015 DB216: a recurring co-orbital companion to Uranus

Minor bodies trapped in 1:1 co-orbital resonances with a host planet could be relevant to explain the origin of captured satellites. Among the giant planets, Uranus has one of the smallest known

A resonant family of dynamically cold small bodies in the near-Earth asteroid belt

Near-Earth objects (NEOs) moving in resonant, Earth-like orbits are potentially important. On the positive side, they are the ideal targets for robotic and human low-cost sample return missions and a

Plutino (15810) 1994 JR1, an accidental quasi-satellite of Pluto

In the Solar system, quasi-satellites move in a 1:1 mean motion resonance going around their host body like a retrograde satellite but their mutual separation is well beyond the Hill radius and the

Crantor, a short-lived horseshoe companion to Uranus

Context. Stable co-orbital motion with Uranus is vulnerable to planetary migration, but temporary co-orbitals may exist today. So far, only two candidates have been suggested, both moving on

A long-lived horseshoe companion to the Earth

We present a dynamical investigation of a newly found asteroid, 2010 SO 16, and the discovery that it is a horseshoe companion of the Earth. The object's absolute magnitude (H = 20.7) makes this the

An asteroidal companion to the Earth

Near-Earth asteroids range in size from a few metres to more than 30 km: in addition to playing an important role in past and present impact rates on the Earth, they might one day be exploited as

The Orbital Evolution of Near-Earth Asteroid 3753

Asteroid 3753 (1986 TO) is in a 1:1 mean motion resonance with Earth, on a complex horseshoe-type orbit. Numerical experiments are performed to determine its medium-term stability and the means by

Discovery of Earth's quasi‐satellite

Abstract— The newly discovered asteroid 2003 YN107 is currently a quasi‐satellite of the Earth, making a satellite‐like orbit of high inclination with apparent period of one year. The term

Asteroids in the inner Solar system – I. Existence

Ensembles of in-plane and inclined orbits in the vicinity of the Lagrange points of the terrestrial planets are integrated for up to 100 Myr. The integrations incorporate the gravitational effects of

Long-term integrations and stability of planetary orbits in our Solar system

We present the results of very long-term numerical integrations of planetary orbital motions over 10 9 -yr time-spans including all nine planets. A quick inspection of our numerical data shows that

Orbital Stability of Planetary Quasi-Satellites

An object having the same mean motion and mean longitude, but different eccentricity than a planet, appears to circle the planet like a retrograde moon. If the distance is large enough such that the

We present here a new solution for the astronomical computation of the orbital motion of the Earth spanning from 0 to −250 Myr. The main improvement with respect to our previous numerical solution

Successive Refinements in Long-Term Integrations of Planetary Orbits

We report on accurate, long-term numerical simulations of the orbits of the major planets in our solar system. The equations of motion are directly integrated by a Störmer multistep scheme, which is
