Short arc orbit determination and imminent impactors in the Gaia era
- Physics, GeologyAstronomy & Astrophysics
- 2018
Short-arc orbit determination is crucial when an asteroid is first discovered. In these cases usually the observations are so few that the differential correction procedure may not converge. We…

A systematic ranging technique for follow-ups of NEOs detected with the Flyeye telescope
- Physics, Geology
- 2019
When new objects are detected in the sky, an orbit determination needs to be performed immediately to find out their origin, to determine the probability of an Earth impact and possibly also to…
Near-Earth Object Orbit Linking with the Large Synoptic Survey Telescope
- Physics
- 2017
We have conducted a detailed simulation of the ability of the Large Synoptic Survey Telescope (LSST) to link near-Earth and main belt asteroid detections into orbits. The key elements of the study…
A NEW WAY OF THINKING ABOUT IMPACT MONITORING OF NEAR-EARTH OBJECTS
- Physics
- 2019
An asteroid just been discovered has a strongly undetermined orbit, being weakly constrained by the few available astrometric observations, and there is a set of possible orbits, all compatible with…
Ground-based astrometry calibrated by Gaia DR1: new perspectives in asteroid orbit determination
- Physics, Geology
- 2017
The Gaia Data Release 1 (GDR1) is a first, important step on the path of evolution of astrometric accuracy towards a much improved situation. Although asteroids are not present in GDR1, this…
New Tools for the Optimized Follow-Up of Imminent Impactors
- Geology, Physics
- 2021
The solar system is populated with, other than planets, a wide variety of minor bodies, the majority of which are represented by asteroids. Most of their orbits are comprised of those between Mars…

Orbit estimation for late warning asteroid impacts: The case of 2014 AA
- Geology2015 IEEE Aerospace Conference
- 2015
We describe a computational technique to assess the near-term Earth impact hazard posed by newly discovered asteroids. In these late warning cases the observational data sets will often include only…
Statistical Ranging of Asteroid Orbits
- Physics, Geology
- 2001
We present a new orbit determination method, termed statistical ranging, applicable to poorly observed single-apparition asteroids having two or more observations. We examine the Bayesian a…
Orbit determination with very short arcs. I admissible regions
- Physics, Geology
- 2004
Most asteroid discoveries consist of a few astrometric observations over a short time span, and in many cases the amount of information is too limited to compute a full orbit according to the least…
From Astrometry to Celestial Mechanics: Orbit Determination with Very Short Arcs
- Physics
- 2005
Contemporary surveys provide a huge number of detections of small solar system bodies, mostly asteroids. Typically, the reported astrometry is not enough to compute an orbit and/or perform an…
Asteroid Close Approaches: Analysis and Potential Impact Detection
- Physics
- 2002
Recently, several new tools and techniques have been developed to allow for robust detection and prediction of planetary encounters and potential impacts by near-Earth asteroids (NEAs). We review the…
Photometric observations of Earth‐impacting asteroid 2008 TC3
- Physics, Geology
- 2011
Abstract– A calibrated lightcurve is presented of the near‐Earth asteroid 2008 TC3, obtained before it impacted Earth on October 7, 2008. The asteroid was observed in unfiltered images from the end…
Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
- Physics, Geology
- 2002
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…
Asteroid Orbit Determination Using Bayesian Probabilities
- Physics, Geology
- 1993
Abstract We determine asteroid orbital elements from optical astrometric observations using Bayesian a priori and a posteriori probability densities. Assuming Gaussian noise statistics and…
