Distribution of the near-earth objects
Solar System Research, 2011This paper analyzes the distribution of the orbits of near-Earth minor bodies from the data on more than 7500 objects. The distribution of large near-Earth objects (NEOs) with absolute magnitudes of H < 18 is generally consistent with the earlier predictions (Bottke et al., 2002; Stuart, 2003), although we have revealed a previously undetected maximum ...

INEO—Imaging of near-Earth objects
Acta Astronautica, 1994Abstract INEO is a program of four explorer flyby missions for imaging near-Earth objects by means of small spin stabilized spacecrafts. A low-cost approach is achieved by using existing hardware and available scientific instrumentation. For the first mission the payload consists of the flight space model of the Halley multicolour camera and three ...

Asteroids and comets probably contributed significantly to the delivery of water and organic materials to the early Earth necessary for the development of life. However, later impacts of near-Earth objects almost certainly played a role in mass extinctions and evolution.

Physical characterization of the near-Earth object population
The European Physical Journal Plus, 2017The Near-Earth Object (NEO) population, being the remnants of the building blocks that originally formed our solar system, allows us to understand the initial conditions that were present in the protosolar nebula. Its investigation can provide crucial information on the origin and early evolution of the solar system, and shed light on the delivery of ...

The population of near-Earth objects discovered by Spacewatch [PDF]
Earth, Moon, and Planets, 1996 In the past three years the Spacewatch program at the University of Arizona’s Lunar and Planetary Laboratory has discovered ~45% of the new Earth Approaching asteroids and found evidence for an unheralded population of small (~10m) objects in the inner solar system.

The chances of a random piece of rock striking Earth still exists, but probably to a much reduced level of threat. During the early years in the creation of our Solar System, there was plenty of debris that had yet to settle into some form and order, with constant collisions of large bodies before any structure was imposed.

The debiased compositional distribution of Near-Earth Objects
2022<p>We report 491 new near-infrared spectroscopic measurements of 420 Near-Earth Objects (NEOs) collected on NASA&#8217;s IRTF in the context of MITHNEOS (PI: DeMeo). The measurements were combined with previously published data (Binzel et al.

Impacting small Near Earth Objects
Advances in Space Research, 2008Abstract The design of a low-cost spacecraft to impact on a small, faint Near Earth Object (NEO), poses major challenges. This paper focuses on the terminal phase of such impact mission, analyzing the capability of autonomous Guidance, Navigation and Control (GNC) systems to compensate the deviations in the impact point to achieve a successful ...

Near Earth object mitigation studies
2016 IEEE Aerospace Conference, 2016Early detection of an object on a collision course with Earth, leading to well-considered and effective measures to mitigate its hazards, is not always possible due to a number of extenuating factors. NASA and the Department of Energy (DOE)'s National Nuclear Security Administration (NNSA) have partnered to develop a full systems framework for ...

Binary Asteroids in the Near-Earth Object Population
Science, 2002Radar images of near-Earth asteroid 2000 DP107 show that it is composed of an ∼800-meter-diameter primary and an ∼300-meter-diameter secondary revolving around their common center of mass. The orbital period of 1.755 ± 0.007 days and semimajor axis of 2620 ± 160 meters constrain the total mass of the system to 4.6 ± 0.5 × 10 11
