Dynamics of the asteroid rings (10199) Chariklo
Вісник Астрономічної школи, 2016 In 2014 it was reported on opening two rings around asteroid (10199) Chariklo (Braga-Ribas F., et al., 2014, Nature, 508, 72–75) and it became the fifth object of the Solar system known to have ring system, after Jupiter, Saturn, Uranus and Neptune.

Feature Scalar Field Grid-Guided Optical-Flow Image Matching for Multi-View Images of Asteroid
Remote Sensing, 2023 Images captured by deep space probes exhibit large-scale variations, irregular overlap, and remarkable differences in field of view. These issues present considerable challenges for the registration of multi-view asteroid sensor images.

Asteroid spin-states of a 4 Gyr collisional family [PDF]
, 2022 Families of asteroids generated by the collisional fragmentation of a common parent body have been identified using clustering methods of asteroids in their proper orbital element space. An alternative method has been developed in order to identify collisional families from the correlation between the asteroid fragment sizes and their proper semi-major

Preatmospheric Detection of a Meter-sized Earth Impactor
The Planetary Science Journal, 2023 On 2020 September 18 U.S. Government (USG) sensors detected a bolide with peak bolometric magnitude of −19 over the Western Pacific. The impact was also detected by the Geostationary Lightning Mapper instrument on the GOES-17 satellite and infrasound ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
Journal of Research in Science Teaching, EarlyView.ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

A Gravitational Tractor for Towing Asteroids [PDF]
, 2005 We present a concept for a spacecraft that can controllably alter the trajectory of an Earth threatening asteroid using gravity as a towline. The spacecraft hovers near the asteroid with thrusters angled outward so the exhaust does not impinge on the surface. This deflection method is insensitive to the structure, surface properties, and rotation state
