Photometric observations of 9 Near-Earth Objects [PDF]
, 2001 We present new CCD observations of nine Near-Earth Asteroids carried out between February, 1999 and July, 2000. The bulk of the data was acquired through an R_C filter, while the minor planet 11405 was observed without filter.

A Near-Earth Object Model Calibrated to Earth Impactors
The Astronomical JournalThe population of Earth-impacting meteoroids and their size-dependent orbital elements are key to understanding the origin of meteorites and informing planetary defense efforts. Outstanding questions include the role of collisions in depleting meteoroids

Spitzer Albedos of Near-Earth Objects [PDF]
The Astronomical Journal, 2019 Abstract Thermal infrared observations are the most effective way to measure asteroid diameter and albedo for a large number of near-Earth objects (NEOs). Major surveys like NEOWISE, NEOSurvey, ExploreNEOs, and NEOLegacy find a small fraction of high albedo objects that do not have clear analogs in the current meteorite population. About

The Sensitivity of NEO Surveyor to Low-perihelion Asteroids
The Planetary Science JournalAsteroids with low orbital perihelion distances experience extreme heating from the Sun that can modify their surfaces and trigger nontypical activity mechanisms.

On the ballistic capture of asteroids for resource utilisation [PDF]
, 2011 This paper investigates the concept of capturing in the Earth’s neighbourhood Earth-approaching objects such as asteroids and comets. These objects may provide access to potential resources, as well as be potential scientific mission opportunities.

VADER: Probing the Dark Side of Dimorphos with LICIACube LUKE
The Planetary Science JournalThe ASI cubesat LICIACube has been part of the first planetary defense mission DART, having among its scopes to complement the DRACO images to better constrain the Dimorphos shape. LICIACube had two different cameras, LEIA and LUKE, and to accomplish its

A Strategy for Finding Near Earth Objects with the SDSS Telescope
, 2004 We present a detailed observational strategy for finding Near Earth Objects (NEOs) with the Sloan Digital Sky Survey (SDSS) telescope. We investigate strategies in normal, unbinned mode as well as binning the CCDs 2x2 or 3x3, which affects the sky ...

The Mission Accessible Near-Earth Objects Survey: Four years of photometry [PDF]
, 2018 Over 4.5 years, the Mission Accessible Near-Earth Object Survey (MANOS) assembled 228 Near-Earth Object (NEO) lightcurves. We report rotational lightcurves for 82 NEOs, constraints on amplitudes and periods for 21 NEOs, lightcurves with no detected ...

Encounter Circumstances of Asteroid 99942 Apophis with the Catalog of Known Asteroids
The Planetary Science JournalAsteroid 99942 Apophis will pass near Earth in 2029 April. Expected to miss our planet by a safe margin, that could change if Apophis's path were perturbed by a collision with another asteroid in the interim.

The Near-Earth Object Surveyor Mission
The Planetary Science Journal, 2023 The Near-Earth Object (NEO) Surveyor mission is a NASA Observatory designed to discover and characterize asteroids and comets. The mission’s primary objective is to find the majority of objects large enough to cause severe regional impact damage (>140 m ...
