Author(s): Greenberg, AH; Margot, J-L; Verma, AK; Taylor, PA; Naidu, SP; Brozovic, M; Benner, LAM | Abstract: Near-Earth asteroid (NEA) 1566 Icarus ($a=1.08\,\mathrm{au}$, e = 0.83, $i=22\buildrel{\circ}\over{.} 8$) made a close approach to Earth in 2015 June at 22 lunar distances (LD). Its detection during the 1968 approach (16 LD) was the first in the history of asteroid radar astronomy. A subsequent approach in 1996 (40 LD) did not yield radar images. We describe analyses of our 2015 radar… Expand
Goldstone Radar Observations of Horseshoe-orbiting Near-Earth Asteroid 2013 BS45, a Potential Mission Target
We report radar observations of near-Earth asteroid 2013 BS45 obtained during the 2013 apparition. This object is in a resonant, Earth-like orbit, and it is a backup target for NASA’s NEA ScoutExpand
Polarimetric Study of Near-Earth Asteroid (1566) Icarus
We conducted a polarimetric observation of the fast-rotating near-Earth asteroid (1566) Icarus at large phase (Sun-asteroid-observer's) angles $\alpha$= 57 deg--141deg around the 2015 summerExpand
Detecting the Yarkovsky effect among near-Earth asteroids from astrometric data
We present an updated set of near-Earth asteroids with a Yarkovsky-related semimajor axis drift detected from the orbital fit to the astrometry. We find 87 reliable detections after filtering for theExpand
An empirical examination of WISE/NEOWISE asteroid analysis and results
Abstract Asteroid observations by the WISE space telescope and the analysis of those observations by the NEOWISE project have provided more information about the diameter, albedo, and otherExpand
Expected precision of Europa Clipper gravity measurements
Abstract The primary gravity science objective of NASA’s Clipper mission to Europa is to confirm the presence or absence of a global subsurface ocean beneath Europa’s Icy crust. Gravity fieldExpand
Prospects of Dynamical Determination of General Relativity parameter beta and Solar quadrupole moment J_{2odot} with Asteroid Radar Astronomy
We evaluated the prospects of quantifying the parameterized post-Newtonian parameter beta and solar quadrupole moment J2 with observations of near-Earth asteroids with large orbital precession ratesExpand
Q-type asteroids: Possibility of non-fresh weathered surfaces
Itokawa particles, which are the recovered samples from the S-complex asteroid 25143 Itokawa by the Hayabusa spacecraft, demonstrate that S-complex asteroids are parent bodies of ordinary chondriteExpand
Central Field Motion with Perturbing Acceleration Varying by the Inverse Square Law: Application to the Yarkovsky Effect
Abstract A mean-element differential equation system is solved analytically in the first approximation in a small parameter to investigate the orbital evolution of an asteroid moving under theExpand

An Adaptive Scheduling Tool to Optimize Measurements to Reach a Scientific Objective: Methodology and Application to Measurements of Stellar Orbits in the Galactic Center
In various fields of physics and astronomy, access to experimental facilities or to telescopes is becoming more and more competitive and limited. It becomes therefore important to optimize the typeExpand


Radar observations and a physical model of Asteroid 1580 Betulia
Abstract We report Arecibo (2380-MHz, 13-cm) observations of Asteroid 1580 Betulia in May–June 2002. We combine these continuous-wave Doppler spectra and delay-Doppler images with optical lightcurvesExpand
Recent radar observations of asteroid 1566 Icarus
Abstract We report Doppler-only radar observations of Icarus at Goldstone at a transmitter frequency of 8510 MHz (3.5 cm wavelength) during 8–10 June 1996, the first radar detection of the objectExpand
Near Earth Asteroids with measurable Yarkovsky effect
Abstract We seek evidence of the Yarkovsky effect among Near Earth Asteroids (NEAs) by measuring the Yarkovsky-related orbital drift from the orbital fit. To prevent the occurrence of unreliableExpand
Yarkovsky Effect on Small Near-Earth Asteroids: Mathematical Formulation and Examples
The Yarkovsky effect is a subtle nongravitational phenomenon related to the anisotropic thermal emission of Solar System objects. Its importance has been recently demonstrated in relation to theExpand
Mainbelt Asteroids: Results of Arecibo and Goldstone Radar Observations of 37 Objects during 1980-1995
Abstract We report detailed results of Arecibo and Goldstone radar observations of 30 mainbelt asteroids (MBAs) during 1980–1995. In addition to estimates of radar cross section, radar albedo, andExpand
The binary near-Earth Asteroid (175706) 1996 FG3 — An observational constraint on its orbital evolution
Abstract Using our photometric observations taken between April 1996 and January 2013 and other published data, we derived properties of the binary near-Earth Asteroid (175706) 1996 FG3 including newExpand
A radar survey of main-belt asteroids: Arecibo observations of 55 objects during 1999–2003
Abstract We report Arecibo observations of 55 main-belt asteroids (MBAs) during 1999–2003. Most of our targets had not been detected previously with radar, so these observations more than double theExpand
Asteroid 1950 DA's Encounter with Earth in 2880: Physical Limits of Collision Probability Prediction
