The Near-Earth Object Surveyor Mission

open access: yesThe Planetary Science Journal, 2023
The Near-Earth Object (NEO) Surveyor mission is a NASA observatory designed to discover and characterize near-Earth asteroids and comets. The mission's primary objective is to find the majority of objects large enough to cause severe regional impact ...

Infrared Lightcurves of Near Earth Objects [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2018
We present lightcurves and derive periods and amplitudes for a subset of 38 near earth objects (NEOs) observed at 4.5 microns with the IRAC camera on the the Spitzer Space Telescope, many of them having no previously reported rotation periods.

Unconfirmed Near-Earth Objects [PDF]

open access: bronzeThe Astronomical Journal, 2018
Abstract We studied the Near-Earth Asteroid (NEA) candidates posted on the Minor Planet Center’s Near-Earth Object Confirmation Page (NEOCP) between years 2013 and 2016. Out of more than 17000 NEA candidates, while the majority became either new discoveries or were associated with previously known objects, about 11% were unable to be ...

Photometric survey of 67 near-Earth objects [PDF]

open access: yesAstronomy & Astrophysics, 2018
Context. The near-Earth object (NEO) population is a window into the original conditions of the protosolar nebula, and has the potential to provide a key pathway for the delivery of water and organics to the early Earth.

Klet Observatory – European Contribution to Detecting and Tracking of Near Earth Objects

open access: diamondGeoinformatics FCE CTU, 2012
Near Earth Object (NEO) research is an expanding field of astronomy. Is is important for solar system science and also for protecting human society from asteroid and comet hazard.  A near-Earth object (NEO) can be defined as an asteroid or comet that has

Are Near Earth Objects the Key to Optimization Theory? [PDF]

open access: greenBritish Journal of Mathematics & Computer Science, 2009
This note suggests that near earth objects and Central Force Optimization have something in common, that NEO theory may hold the key to solving some vexing problems in deterministic optimization: local trapping and proof of convergence. CFO analogizes Newton's laws to locate the global maxima of a function.

ExploreNEOs I: Description and first results from the Warm Spitzer NEO Survey [PDF]

open access: bronze, 2010
We have begun the ExploreNEOs project in which we observe some 700 Near Earth Objects (NEOs) at 3.6 and 4.5 microns with the Spitzer Space Telescope in its Warm Spitzer mode.

NEOWISE Observations of Near-Earth Objects: Preliminary Results [PDF]

open access: yesThe Astrophysical Journal, 2011
With the NEOWISE portion of the \emph{Wide-field Infrared Survey Explorer} (WISE) project, we have carried out a highly uniform survey of the near-Earth object (NEO) population at thermal infrared wavelengths ranging from 3 to 22 $\mu$m, allowing us to ...

Directed Energy Active Illumination for Near-Earth Object Detection [PDF]

open access: green, 2014
On 15 February 2013, a previously unknown ~20 m asteroid struck Earth near Chelyabinsk, Russia, releasing kinetic energy equivalent to ~570 kt TNT. Detecting objects like the Chelyabinsk impactor that are orbiting near Earth is a difficult task, in part ...

First Results from the rapid-response spectrophotometric characterization of Near-Earth Objects [PDF]

open access: bronze, 2019
As part of our multi-observatory, multi-filter campaign, we present \rmi color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic telescope at the San Pedro Martir's National Observatory in Mexico.
