Colors and Dynamics of a Near-Sun Orbital Asteroid Family: 2021 PH27 and 2025 GN1
Scott Sheppard, Henry Hsieh, Petr Pokorny +6
We observed the dynamically similar near-Sun asteroids 2021 PH27 and 2025 GN1 for their optical colors. These objects have the lowest known semi-major axes of any asteroids. 2021 P…
Discovery and Characteristics of the Rapidly Rotating Active Asteroid (62412) 2000 SY178 in the Main Belt
Scott Sheppard, Chadwick Trujillo
We report a new active asteroid in the main belt of asteroids between Mars and Jupiter. Object (62412) 2000 SY178 exhibited a tail in images collected during our survey for objects…
A Southern Sky and Galactic Plane Survey for Bright Kuiper Belt Objects
Scott Sheppard, Andrzej Udalski, Chad Trujillo +6
About 2500 square degrees of sky south of declination -25 degrees and/or near the galactic plane were surveyed for bright outer solar system objects. This survey is one of the firs…
The Albedos, Sizes, Colors and Satellites of Dwarf Planets Compared with Newly Measured Dwarf Planet 2013 FY27
Scott Sheppard, Yanga Fernandez, Arielle Moullet
2013 FY27 is the ninth intrinsically brightest Trans-Neptunian Object (TNO). We observed 2013 FY27 at thermal wavelengths with ALMA and in the optical with Magellan to determine it…
Observational Investigation of the 2013 Near-Earth Encounter by Asteroid (367943) Duende
Nicholas Moskovitz, Conor Benson, Daniel Scheeres +20
On 15 February 2013, the asteroid 367943 Duende (2012 DA14) experienced a near-Earth encounter at an altitude of 27,700 km or 4.2 Earth radii. We present here the results of an ext…
All planetesimals born near the Kuiper Belt formed as binaries
Wesley C. Fraser, Michele t. Bannister, Rosemary E. Pike +19
The cold classical Kuiper belt objects have low inclinations and eccentricities and are the only Kuiper belt population suspected to have formed in situ. Compared with the dynamica…
