Orbiting the Sun at an average distance of 0.59 au and with the shortest aphelion of any known minor body, at 0.77 au, the Atira-class asteroid 2019 AQ3 may be an orbital outlier or perhaps an early indication of the presence of a new population of objects: those following orbits entirely encompassed within that of Venus, the so-called Vatiras. Here, we explore the orbital evolution of 2019 AQ3 within the context of the known Atiras to show that, like many of them, it displays a present-day…

A Twilight Search for Atiras, Vatiras, and Co-orbital Asteroids: Preliminary Results
Near-Earth objects (NEOs) that orbit the Sun on or within Earth’s orbit are tricky to detect for Earth-based observers due to their proximity to the Sun in the sky. These small bodies hold clues to
Physical characterization of 2020 AV2, the first known asteroid orbiting inside Venus orbit
The first known asteroid with the orbit inside that of Venus is 2020 AV2. This may be the largest member of a new population of small bodies with the aphelion smaller than 0.718 au, called Vatiras.
Near the Edge of the Atira Orbital Realm: Short-term Dynamical Evolution of 2020 HA10 and 2020 OV1
Atiras or Interior Earth Objects (IEOs) have their orbits contained entirely within the orbit of Earth. The first IEO, 1998 DK36, was found in 1998; out of the 23 known Atiras, 15 have been
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


Kozai–Lidov Resonant Behavior Among Atira-class Asteroids
Atira-class asteroids have aphelia greater than 0.718 au and smaller than 0.983 au. It has been found that the orbits of many of them remain relatively stable for at least 1 Myr, but it is unclear
On the dynamical evolution of 2002 VE68
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

The Chelyabinsk superbolide: a fragment of asteroid 2011 EO40?
Bright fireballs or bolides are caused by meteoroids entering the Earth's atmosphere at high speed. On 2013 February 15, a superbolide was observed in the skies near Chelyabinsk, Russia. Such a
Flipping minor bodies: what comet 96P/Machholz 1 can tell us about the orbital evolution of extreme trans-Neptunian objects and the production of near-Earth objects on retrograde orbits
Nearly all known extreme trans-Neptunian objects (ETNOs) have argument of perihelion close to 0 degrees. An existing observational bias strongly favours the detection of ETNOs with arguments of
Dancing with Venus in the shadow of the Earth: a pair of genetically related near-Earth asteroids trapped in a mean-motion resonance
YORP-induced fission events may form dynamically coherent pairs or even families of asteroids. The outcome of this process is well documented among members of the main asteroid belt, but not in the
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
Possible long-lived asteroid belts in the inner Solar System
Recent years have seen the discovery of several objects in stable orbits in the outer Solar System; these bodies include objects in the Kuiper belt (also known as the Kuiper–Edgeworth belt) as well
