LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large Synoptic…

Proper element catalogs and asteroid families
Using the synthetic theory, we computed proper elements for asteroids in the inner part of the main belt and in the trans-Neptunian region. We present the new results and we discuss some important…

Asteroid Proper Elements and the Dynamical Structure of the Asteroid Main Belt
Abstract We have computed proper elements for 12,573 asteroids, including all the ones with orbits accurate enough to be useful for family identification. This was done with an upgraded version of…

Quantifying the Risk Posed by Potential Earth Impacts
TLDR
A new hazard scale that will describe the risk posed by a particular potential impact in both absolute and relative terms is proposed and described, which reflects the urgency of the situation in a natural way and thus can guide specialists in assessing the computational and observational effort appropriate for a given situation.

The Trojan asteroid belt: Proper elements, stability, chaos and families
I have computed proper elements for 174 asteroids in the 1 : 1 resonance with Jupiter, that is for all the reliable orbits available (numbered and multi-opposition). The procedure requires numerical…

Measurement of Jupiter’s asymmetric gravity field
TLDR
Measurements of Jupiter’s gravity harmonics are reported through precise Doppler tracking of the Juno spacecraft in its polar orbit around Jupiter, finding a north–south asymmetry, which is a signature of atmospheric and interior flows.

Orbit determination of space debris: admissible regions
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 observations of a…
