Open Astronomy, 2015 We cast a retrospective look at the mankind’s acquaintance with minor bodies of the Solar System, at the explosive growth in their discoveries resulting from the technological progress, and at gradual understanding of the danger to our very existence ...

The Proximities of Asteroids and Critical Points of the Distance Function [PDF]
Serbian Astronomical Journal, 2010 The proximities are important for different purposes,for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets.

A potential survival strategy during the late heavy bombardment [PDF]
Serbian Astronomical Journal, 2023 The Late Heavy Bombardment (LHB) represents a period of time in which an increased number of impactors collided with the Earth. While there were continuous collisions of impactors globally, these would be perceived by populations of life as ...

Survey of secular resonances in the asteroid belt [PDF]
Serbian Astronomical Journal, 2022 Using a recently introduced synthetic method to compute the asteroid secular frequencies (Knežević and Milani 2019), in this paper we survey the locations of secular resonances in the 9 dynamically distinct zones of the asteroid belt.

Third derivatives of the integrable part of an asteroid Hamiltonian [PDF]
Serbian Astronomical Journal, 2007 To apply the theorem of Nekhoroshev (1977) to asteroids, one first has to check whether a necessary geometrical condition is fulfilled: either convexity, or quasi-convexity, or only a 3-jet non-degeneracy.

Computation of asteroid proper elements on the Grid [PDF]
Serbian Astronomical Journal, 2009 A procedure of gridification of the computation of asteroid proper orbital elements is described. The need to speed up the time consuming computations and make them more efficient is justified by the large increase of observational data expected from the

Genetic optimization of asteroid families’ membership
Frontiers in Astronomy and Space Sciences, 2022 Asteroid families are groups of asteroids with a common origin, such as prior collisions or the parent body’s rotational fission. In proper [a, e, sin(i)] element domains, they are generally observed using the hierarchical clustering technique (HCMs ...

Computation of asteroid proper elements: Recent advances [PDF]
Serbian Astronomical Journal, 2017 The recent advances in computation of asteroid proper elements are briefly reviewed. Although not representing real breakthroughs in computation and stability assessment of proper elements, these advances can still be considered as important improvements

Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets
The Astronomical Journal, 2023 We complete the publication of all microlensing planets (and “possible planets”) identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields during the 2019 observing season, namely, KMT-2019-BLG-0298, KMT-2019-BLG ...

Asteroid spin-rate studies using large sky-field surveys
Geoscience Letters, 2017 Eight campaigns to survey asteroid rotation periods have been carried out using the intermediate Palomar Transient Factory in the past 3 years. 2780 reliable rotation periods were obtained, from which we identified two new super-fast rotators (SFRs ...
