Some detailed astronomical and applied aspects deflection of hazardous near-Earth objects (NEO) by direct high concentrated sunlight, causing intensive local ablation of their surfaces, are considered. The major requirements to solar concentrating optics within a single collector (a large mirror) approach, along with the asteroid properties being most substantial in achieving the predetermined effect for the period less than a year (mid-thrust action), are discussed. Such a hastened strategy…

Physical limits of solar collectors in deflecting Earth-threatening asteroids
Abstract This paper investigates the physical limits of a solar collector for orbit deflection of near-Earth asteroids (NEAs) on a collision course with Earth. For decades of warning time a small
Deflecting APOPHIS with a flotilla of solar shields
Abstract The possibility to use the photonic pressure from the Sun for acting upon the orbit of a man-made object is well known. What is presented in this paper is the capacity to use a solar sail
A multi-mirror solution for the deflection of dangerous NEOS
This paper presents some recent results on the deflection of potentially dangerous near earth objects. A particular deflection technique, employing a swarm of mirrors focusing the light of the Sun on
Meteoroids, Meteors, and the Near-Earth Object Impact Hazard
In considering the modern-day hazard from infalling near-Earth asteroids and comets, the focus has shifted toward the smallest, most frequent impacts that can do damage on the ground, like the 1908
NEOWISE OBSERVATIONS OF NEAR-EARTH OBJECTS: PRELIMINARY RESULTS
With the NEOWISE portion of the 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
Optimal deflection of NEOs en route of collision with the Earth
Abstract Recently, a method for the n -body analysis of the velocity change required to deflect a hazardous near-Earth object (NEO) was presented by Carusi et al. [Carusi, A., Valsecchi, G.B.,
Dynamics and control of a solar collector system for near Earth object deflection
A solar collector system is a possible method using solar energy to deflect Earth-threatening near-Earth objects. We investigate the dynamics and control of a solar collector system including a main
Deflection of near-Earth asteroids by kinetic energy impacts from retrograde orbits
Abstract Previous studies of non-nuclear diversion of near Earth asteroids have largely ignored the use of pure kinetic energy impacts, partly due to apparent limits on impact speeds of 10– 15 km s
Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
The orbital and absolute magnitude distribution of the near-Earth objects (NEOs) is difficult to compute, partly because only a modest fraction of the entire NEO population has been discovered so
On the deflection of asteroids with mirrors
This paper presents an analysis of an asteroid deflection method based on multiple solar concentrators. A model of the deflection through the sublimation of the surface material of an asteroid is
