In this work, we investigate the size, thermal inertia, surface roughness, and geometric albedo of 10 Vesta family asteroids using the Advanced Thermophysical Model (ATM), based...

Kuiper Belt Object (385446) Manwe-Thorondor is a multiobject system with mutual events predicted to occur from 2014 to 2019. To detect the events, we observed the system at 4...

The Yarkovsky effect is a thermal process acting upon the orbits of small celestial bodies, which can cause these orbits to slowly expand or contract with time. The effect is...

We report on our detailed characterization of Earth's second known temporary natural satellite, or minimoon, asteroid 2020CD3. An artificial origin can be ruled out based on its...

We initiated the bilateral collaboration between the Lulin Observatory and the Purple Mountain Observatory to collect asteroid lightcurves using the Chinese Near-Earth Object...

Asteroid 2012TC4 is a small (~10m) near-Earth object that was observed during its Earth close approaches in 2012 and 2017. Earlier analyses of light curves revealed its excited...

The large time span and precise observational data of natural satellites is of great significance for updating their ephemerides and studying their dynamic characteristics. With...

Sputnik Planitia, Pluto's gigantic, volatile ice glacier, hosts numerous scientific mysteries, including the presence of thousands of elongated pit structures. We examine...

We report 491 new near-infrared spectroscopic measurements of 420 near-Earth objects (NEOs) collected on the NASA InfraRed Telescope Facility as part of the MIT-Hawaii NEO...

We report a new determination of the orbits of the irregular Saturnian satellites. We fit their numerically integrated orbits to a data set containing Earth-based observations...

The five major Uranian satellites (Ariel, Umbriel, Titania, Oberon, and Miranda) were observed by a 1.56m telescope at Sheshan Station of Shanghai Astronomical Observatory...

The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these...

A novel algorithm based on the Lindstedt-Poincare method is proposed to construct an analytical solution of the lunar orbit. Based on the analytical solution, a numerical...

Mean plane measurements of the Kuiper Belt from observational data are of interest for their potential to test dynamical models of the solar system. Recent measurements have...

We present photometric data for minor planets observed by the Transiting Exoplanet Survey Satellite during its Cycle 1 operations. In total we extracted usable detections for...

We report on the ephemeris development for Menoetius, the satellite of Patroclus. Our data set consisted of ground-based and Hubble Space Telescope relative astrometry, as well...

We present the methods and results from the discovery and photometric measurement of 26 bright VR>24 trans-Neptunian objects (TNOs) during the first year (2019-20) of the...

We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project. Of these 110 TNOs, 105 do not...

We present results from observations of 238 near-Earth objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic telescope at San Pedro Martir's National Observatory...

We present the results of a wide-field survey using the 1.2m Samuel Oschin Telescope at Palomar Observatory. This survey was designed to find the most distant members of the...
