The steady-state population of Earth's co-orbitals of lunar provenance
Elisa Maria Alessi, Robert Jedicke
The population of natural objects in a 1:1 mean motion resonance with Earth are known as Earth's co-orbitals. Main belt objects can dynamically evolve into Earth co-orbitals but ta…
Apache Point rapid response characterization of primitive imminent impactor 2024 RW
Carl Ingebretsen, Bryce T. Bolin, Robert Jedicke +6
Imminent impactors may be detected only a few hours before their impact with Earth, providing a brief opportunity to characterize them before impact. We describe the characterizati…
The steady state population of Earth's minimoons of lunar provenance
Robert Jedicke, Elisa Maria Alessi, Naja Wiedner +3
This work examines the plausibility of a lunar origin of natural objects that have a negative total energy (ET) with respect to the geocenter while within 3 Earth Hill radii (RH),…
Keck and Gemini characterization of rendezvous target 1998 KY
Bryce T. Bolin, Christoffer Fremling, Matthew Belyakov +7
Near-earth object (NEO) 1998 KY is a target of the spacecraft, which it will rendezvous with in July 2031. The asteroid is a rapid rotator and has a large out-…
The discovery and characterization of Earth-crossing asteroid 2024 YR
Bryce T. Bolin, Josef Hanuš, Larry Denneau +9
We describe observations and physical characteristics of Earth-crossing asteroid 2024 YR, discovered on 2024 December 27 by the Asteroid Terrestrial-impact Last Alert System. T…
The discovery and characterization of minimoon 2024 PT
Bryce T. Bolin, Larry Denneau, Laura-May Abron +4
Minimoons are asteroids that become temporarily captured by the Earth-Moon system. We present the discovery of 2024 PT, a minimoon discovered by the Asteroid Terrestrial-impact…
