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 Facility on 4 January 2020 is the first known object on a Vatira orbit. Numerical integrations of 2020 AV$_2$'s nominal orbit show it remaining in the Vatira region for the next few hundred kyr before coupling to Venus and evolving onto an Atira orbit (NEOs entirely interior to Earth's orbit with $0.718<Q<0… Expand

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.Expand
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
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
Exploring the Solar System with the NOIRLab Source Catalog I: Detecting Objects with CANFind
Despite extensive searches and the relative proximity of solar system objects (SSOs) to Earth, many remain undiscovered and there is still much to learn about their properties and interactions. ThisExpand

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


The orbital distribution of Near-Earth Objects inside Earth's orbit
Canada’s Near-Earth Object Surveillance Satellite (NEOSSat), set to launch in early 2012, will search for and track Near-Earth Objects (NEOs), tuning its search to best detect objects with a < 1.0Expand
Debiased orbit and absolute-magnitude distributions for near-Earth objects
Abstract The debiased absolute-magnitude and orbit distributions as well as source regions for near-Earth objects (NEOs) provide a fundamental frame of reference for studies of individual NEOs andExpand
