    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). …”

    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. …”
