Classifying and Characterizing the Evolution of the Minimum Orbit Intersection Distance for Near-Earth Asteroids

The Planetary Science Journal
In this paper, the minimum orbit intersection distances (MOIDs) of near-Earth asteroids (NEAs) over the next 200 yr are computed and analyzed in detail. It is shown that the MOID of an NEA relative to the Earth–Moon barycenter is usually a better metric ...

The Discovery and Characterization of Minimoon 2024 PT5

The Astrophysical Journal Letters
Minimoons are asteroids that become temporarily captured by the Earth–Moon system. We present the discovery of 2024 PT _5 , a minimoon discovered by the Asteroid Terrestrial-impact Last Alert System Sutherland telescope on 2024 August 7.

Observations of Near Earth Objects with Spitzer

, 2016
We are carrying out an Exploration Science Warm Spitzer program entitled NEOSurvey in which we are observing 550 Near Earth Objects in 710 hours of Spitzer time. For each object we use a thermal model to derive diameter and albedo. For each object we also derive a (partial) lightcurve; total elapsed observing times range from 15 minutes to 3.2 hours ...

NEOWISE Data Processing and Color Corrections for Near-Earth Asteroid Observations

The Planetary Science Journal
The Wide-field Infrared Survey Explorer and NEOWISE missions are a key source of thermal data for near-Earth asteroids (NEAs). These missions, which utilized a space-based platform in Earth orbit, produced thermal images across four different wavelength ...

Near earth objects space observatory

, 2015
In this Master Thesis we begin with an introduction about Near Earth Objects (NEOs). We start with the different kind of existing NEOs, and then we will focus more on which ones can represent the biggest hazard for Earth. Thus many studies suggest irrelevant number of meteorites hit the earth each year, but actually is very hard to know number of exact
