Determining orbits for natural and artificial celestial bodies is an essential step in the
exploration and understanding of the Solar System. However, recent progress in the quality …

Abstract 1I/'Oumuamua is the first confirmed interstellar body in our solar system. Here we
report on observations of'Oumuamua made with the Spitzer Space Telescope on 2017 …

The main problem in the orbit determination of the space debris population orbiting our
planet is identifying which separate sets of data belong to the same physical object. The …

We assess the risk of an Earth impact for asteroid (99942) Apophis by means of a statistical
analysis accounting for the uncertainty of both the orbital solution and the Yarkovsky effect …

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 …

When a new near Earth asteroid is discovered, it is important to know whether or not there is
the possibility of an impact with the Earth in the near future. In this paper, we describe the …

When the observational data are not enough to compute a meaningful orbit for an
asteroid/comet we can represent the data with an attributable, ie, two angles and their time …

Aims. The primary objective of this study is to utilize Gaia DR3 asteroid astrometry to detect
the Yarkovsky effect, a non-gravitational acceleration that affects the orbits of small …

This paper addresses the problem of minimizing the impact of nonlinearities when dealing
with uncertainty propagation in the perturbed two-body problem. The recently introduced …

The potentially hazardous Asteroid (101955) 1999 RQ36 has a possibility of colliding with
the Earth in the latter half of the 22nd century, well beyond the traditional 100-year time …
