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. The surface of 2020 AV2 is being constantly modified by the high temperature, by the strong solar wind irradiation that characterizes the innermost region of the Solar system, and by high-energy micrometeorite impacts. The study of its physical properties represents an extreme test-case for the… Expand

Roaming the Relativistic Realm: Short-term Dynamical Evolution of Atira 2021 PH27
General relativity effects coupled with those derived from the von Zeipel–Lidov–Kozai mechanism may play a significant role on the evolution of members of the Atira dynamical class, particularly inExpand

Observations and computer simulations of their orbits and interactions with planets yield insights into the asteroids’ dynamic lives.


Orbital dynamics of 2020 AV2: the first Vatira asteroid
Vatira-class near-Earth objects (NEOs) have orbits entirely interior to the orbit of Venus with aphelia $0.307<Q<0.718$ AU. Recently discovered asteroid 2020 AV$_2$ by the Zwicky Transient FacilityExpand
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 solarExpand
Near-Earth asteroids spectroscopic survey at Isaac Newton Telescope
Context. The population of near-Earth asteroids (NEAs) shows a large variety of objects in terms of physical and dynamical properties. They are subject to planetary encounters and to strong solarExpand
Understanding the evolution of Atira-class asteroid 2019 AQ3, a major step towards the future discovery of the Vatira population
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 anExpand
A spectroscopic survey of the small near-Earth asteroid population: Peculiar taxonomic distribution and phase reddening
Abstract We present the results of the first-ever visible spectroscopic survey fully dedicated to the small (absolute magnitude H ≥ 20) near-Earth asteroid (NEA) population. Observations have beenExpand
Olivine-rich asteroids in the near-Earth space
In the framework of a 30-night spectroscopic survey of small near-Earth asteroids (NEAs) we present new results regarding the identification of olivine-rich objects. The following NEAs wereExpand
Evidence for a Circumsolar Dust Ring Near Mercury’s Orbit
To test a technique to be used on the white-light imager onboard the recently launched Parker Solar Probe mission, we performed a numerical differentiation of the brightness profiles along theExpand
An extension of the Bus asteroid taxonomy into the near-infrared
An asteroid taxonomy classification system based on reflectance spectrum characteristics for 371 asteroids measured over the wavelength range 0.45 to 2.45 μm is presented and nearly all of the Bus taxonomy classes are preserved, with one new class (Sv). Expand
Spectral properties of near-Earth and Mars-crossing asteroids using Sloan photometry
The nature and origin of the asteroids orbiting in near-Earth space, including those on a potentially hazardous trajectory, is of both scientific interest and practical importance. We aim here atExpand
