Close encounters of Near Earth Objects with large asteroids [PDF]
, 2014 Close encounters of Near Earth Objects (NEOs) with large asteroids are a possible source of systematic errors in trajectory propagations and asteroid mitigation. It is, thus, necessary to identify those large asteroids that have to be considered as perturbers in NEO orbit modeling.

Main belt asteroids taxonomical information from Dark Energy Survey data [PDF]
arXiv, 2023 While proper orbital elements are currently available for more than 1 million asteroids, taxonomical information is still lagging behind. Surveys like SDSS-MOC4 provided preliminary information for more than 100,000 objects, but many asteroids still lack even a basic taxonomy.

Post-Cataract Surgery Visual Disturbance in a Retinitis Pigmentosa Patient with Asteroid Hyalosis
Case Reports in Ophthalmology, 2011 A patient with retinitis pigmentosa showed visual disturbances following successful cataract surgery. He had a dense asteroid hyalosis in the eye before cataract surgery. After the surgery he noticed that his vision became worse.

Identification and Dynamical Properties of Asteroid Families [PDF]
, 2015 Asteroids formed in a dynamically quiescent disk but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, many dozen large asteroids have been disrupted by impacts over the age of the Solar System, producing groups of fragments known as asteroid families.

Symposium - International Astronomical Union, 1986 Using a number of different conventional observing methods of astronomy like spectrophotometry, polarimetry, IR-radiometry and UBV-photometry, physical properties of asteroids can be derived, such as diameters, spectral reflectivity and albedo. Based on observable parameters a classification in terms of taxonomic types can be made and the mineralogy of

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 ...

AVAST Survey 0.4-1.0 μm Spectroscopy of Igneous Asteroids in the Inner and Middle Main Belt [PDF]
, 2012 We present the spectra of 60 asteroids, including 47 V-types observed during the first phase of the Adler V-Type Asteroid (AVAST) Survey. SDSS photometry was used to select candidate V-type asteroids for follow up by nature of their very blue $i-z$ color.

Diversity, 2023 Xyloplax is a genus of three species of sea stars previously found only on sunken wood in the deep ocean. Their circular and petaloid bodies, which lend them their common name “sea daisy”, and their presumed exclusive diet of wood make them an unusual ...

Modelling Detection Distances to Small Bodies Using Spacecraft Cameras
Modelling, 2023 Small bodies in the Solar System are appealing targets for scientific and technological space missions, owing to their diversity in intrinsic and extrinsic properties, besides orbit and other factors.

P/2017 S5: Another Active Asteroid Associated with the Theobalda Family [PDF]
Research Notes of the American Astronomical Society, Volume 2,
Issue 3, id. 129, 2018, 2018 In this note we have shown that a newly discovered comet P/2017 S5 (ATLAS), that moves around the Sun in an asteroid-like orbit, is a member of the Theobalda asteroid family.
