BYORP and Dissipation in Binary Asteroids: Lessons from DART
The Planetary Science JournalThe near-Earth binary asteroid Didymos was the target of the planetary defense demonstration mission DART in 2022 September. The smaller binary component, Dimorphos, was impacted by the spacecraft in order to measure momentum transfer in kinetic impacts ...

DART Impact Ejecta Plume Evolution: Implications for Dimorphos
The Planetary Science JournalThe NASA Double Asteroid Redirection Test (DART) spacecraft impacted the moon Dimorphos of the [65803] Didymos binary system and changed the binary orbit period, demonstrating asteroid deflection by a kinetic impact and indicating that more momentum was ...

Machine-learning identification of asteroid groups
Monthly notices of the Royal Astronomical Society, 2019 Asteroid families are groups of asteroids that share a common origin. They can be the outcome of a collision or be the result of the rotational failure of a parent body or its satellites.

Asteroid Detection using Machine Learning Algorithm
, 2020 My paper starts from the question many of us wonder ‘What if an Asteroid hit Earth? The answer depends on how big an asteroid is in terms of dimension- Let’s say an asteroid of baseball ground hits earth, which can completely erase a city.

EXTREME AO OBSERVATIONS OF TWO TRIPLE ASTEROID SYSTEMS WITH SPHERE [PDF]
, 2016 We present the discovery of a new satellite of asteroid (130) Elektra—S/2014 (130) 1—in differential imaging and in integral field spectroscopy data over multiple epochs obtained with Spectro-Polarimetric High-contrast Exoplanet Research/Very Large ...

The Secular Dynamical Evolution of Binary Asteroid System (65803) Didymos Post-DART
The Planetary Science JournalThe successful impact of NASA’s DART mission with Dimorphos, the secondary body of binary asteroid system (65803) Didymos, altered the attitude, shape, and orbit of Dimorphos.

Reconnecting groups of space debris to their parent body through proper elements
Scientific Reports, 2021 Satellite collisions or fragmentations generate a huge number of space debris; over time, the fragments might get dispersed, making it difficult to associate them to the configuration at break-up.

Asteroid 2015 DB216: a recurring co-orbital companion to Uranus [PDF]
, 2015 Minor bodies trapped in 1:1 co-orbital resonances with a host planet could be relevant to explain the origin of captured satellites. Among the giant planets, Uranus has one of the smallest known populations of co-orbitals, three objects, and all of them ...

The Cumulation of Debris Clouds around a Fast-rotating Asteroid
The Astrophysical JournalThe rotational mass loss has been realized to be a prevalent mechanism to produce low-speed debris near the asteroid, and the size composition of the asteroid’s surface regolith has been closely measured by in situ explorations.
