    Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams by M.G. Sokolova, M.V. Sergienko

    Published 2016-12-01
    “…The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the proportionality of their orbits with the orbits of asteroids. …”

    The NEO Surveyor Near-Earth Asteroid Known Object Model by Tommy Grav, Amy K. Mainzer, Joseph R. Masiero, Dar W. Dahlen, Tim Spahr, William F. Bottke, Frank J. Masci

    Published 2023-01-01
    “…An essential component of the next generation of NEO surveys is an understanding of the population of known objects, including an accounting of the discovery rate per year as a function of size. Using a near-Earth asteroid (NEA) reference model developed for NASA’s NEO Surveyor (NEOS) mission and a model of the major current and historical ground-based surveys, an estimate of the current NEA survey completeness as a function of size and absolute magnitude has been determined (termed the Known Object Model; KOM). …”

    Non-zero Yarkovsky acceleration for near-Earth asteroid (99942) Apophis by Jorge A. Pérez-Hernández, Luis Benet

    Published 2022-01-01
    “…The Yarkovsky acceleration acting on near-Earth asteroid (99942) Apophis is large enough to require consideration when evaluating the object’s course and future close passes of Earth, according to an analysis of astrometry data collected including the 2021 flyby.…”

    A common origin for dynamically associated near-Earth asteroid pairs by Binzel, Richard P, DeMeo, Francesca E, Person, Michael J

    Published 2020
    “…Though pairs of dynamically associated asteroids in the Main Belt have been identified and studied for over a decade, very few pair systems have been identified in the near-Earth asteroid population. We present data and analysis that supports the existence of two genetically related pairs in near-Earth space. …”

    Tidal Disruption of Near-Earth Asteroids during Close Encounters with Terrestrial Planets by Mikael Granvik, Kevin J. Walsh

    Published 2024-01-01
    “…Numerical modeling has long suggested that gravitationally bound (or so-called rubble-pile) near-Earth asteroids (NEAs) can be destroyed by tidal forces during close and slow encounters with terrestrial planets. …”

    Spectral and spin measurement of two small and fast-rotating near-Earth asteroids by Polishook, David, Lockhart, Matthew, Golisch, W., Bus, S. J., Gulbis, Amanda A. S., DeMeo, Francesca E, Binzel, Richard P

    Published 2014
    “…Their spectral characteristics are somewhat atypical among near-Earth asteroids: C-complex for 2012 KP24 and B-type for 2012 KT42, from which we interpret the albedos of both asteroids to be between 0.10 and 0.15 and maximum effective diameters of 20 ± 6 and 6 ± 1 m, respectively. …”
