Secular evolution of asteroid families: the role of Ceres
, 2015 We consider the role of the dwarf planet Ceres on the secular dynamics of the asteroid main belt. Specifically, we examine the post impact evolution of asteroid families due to the interaction of their members with the linear nodal secular resonance with

Dynamic autonomous intelligent control of an asteroid lander [PDF]
, 2010 One of the future flagship missions of the European Space Agency (ESA) is the asteroid sample return mission Marco-Polo. Although there have been a number of past missions to asteroids, a sample has never been successfully returned.

Massenbegriffe auf dem Prüfstand: Die drei Facetten der Masse
Physik in unserer Zeit, EarlyView.Masse ist die primäre Eigenschaft, die man physikalischen Körpern zuordnet. Da die Masse verschiedene Rollen übernimmt – so reagiert sie nicht nur auf ein Gravitationsfeld, sie erzeugt auch eines –, müssen diese verschiedenen Rollen und darauf aufbauend die verschiedenen Massenbegriffe genauer analysiert werden.

Excitation and Depletion of the Asteroid Belt in the Early Instability Scenario [PDF]
Astronomical Journal, 2018 Containing only a few percentages of the mass of the moon, the current asteroid belt is around three to four orders of magnitude smaller than its primordial mass inferred from disk models. Yet dynamical studies have shown that the asteroid belt could not

Nachtsicht ins All mit dem bloßen Auge: Sag mir, wie weit die Sterne steh'n
Physik in unserer Zeit, EarlyView.Beim Blick in den Nachthimmel sehen wir ohne optische Hilfsmittel und abhängig von der lokalen Lichtverschmutzung viele Hundert bis maximal einige Tausend Sterne und auch einige Galaxien. Aber wie weit sind diese von uns entfernt? Und bis zu welchen maximalen Entfernungen können wir Objekte im Weltall mit dem bloßen Auge wahrnehmen?

Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2016 The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the ...

Erosion Rate Measurements for DART Spacecraft Ion Propulsion System
Applied Sciences, 2022 The Double Asteroid Redirection Test (DART) spacecraft was developed to provide the first measurement for orbital deflection of an asteroid upon intentional impact. The NEXT ion engine is part of the mission, on its maiden voyage.

The OSIRIS-REx Visible and InfraRed Spectrometer (OVIRS): Spectral Maps of the Asteroid Bennu [PDF]
, 2017 The OSIRIS-REx Visible and Infrared Spectrometer (OVIRS) is a point spectrometer covering the spectral range of 0.4 to 4.3 microns (25,000–2300 cm−1). Its primary purpose is to map the surface composition of the asteroid Bennu, the target asteroid of the
