The evolution of the Line of Variations at close encounters: an analytic approach
Giovanni Battista Valsecchi, Alessio Del Vigna, Marta Ceccaroni
We study the post-encounter evolution of fictitious small bodies belonging to the so-called Line of Variations (LoV) in the framework of the analytic theory of close encounters. We…

Near-Earth asteroid (410777) 2009 FD is a potentially hazardous asteroid with potential impacts on Earth at the end of the 22nd century. The astrometry collected during the 2019 ap…
Short arc orbit determination and imminent impactors in the Gaia era
F. Spoto, A. Del Vigna, A. Milani +6
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…
