On 21 July 1969, during the first manned lunar mission, Apollo 11, retroreflector array was placed on moon, enabling highly accurate measurements of Earthmoon separation by means laser ranging. Lunar ranging (LLR) turns system into a laboratory for broad range investigations, including astronomy, science, gravitational physics, geodesy, and geodynamics. Contributions from LLR include three-orders-of-magnitude improvement in accuracy ephemeris, several-orders-of-magnitude measurement...
The discovery rate of near-Earth asteroids (NEAs) has steadily increased over the past three decades, yet physical characterization these objects not kept pace. In an effort to help address this gap, we combined targeted photometric observations, archival data, and sparse data from Asteroid Terrestrial-impact Last Alert System (ATLAS) survey extract as much information possible about NEAs' rotation rates, spin-axis orientations, shapes. We selected 17 NEAs with a potential for shape...
Asteroid pairs are genetically related asteroids that recently separated ($<$few million years), but still reside on similar heliocentric orbits. A few hundred of these systems have been identified, primarily in the asteroid main-belt. Here we studied a newly discovered pair near-Earth objects (NEOs): 2019 PR2 and QR6. Based broad-band photometry, found to be spectrally D-types, type rare amongst NEOs. We recovered astrometric observations for both from Catalina Sky Survey 2005, which...
2012 is one of the known solar system objects with largest aphelion distance, exceeding 2200 au, on a high inclination orbit (i = 78°). It has been recognized to be either borderline representative inclination, perihelion distance (HiHq) objects, or even new class bodies, similar HiHq for but an in inner Oort Cloud. Here, we present photometry using long-term data from 2000 2013 taken by SDSS sky survey, ESO MPG 2.2 m and McDonald 2.1 telescopes, visual+near-infrared spectrum Southern...
