We measured the system-integrated thermal emission of the binary Kuiper Belt object (47171 ) 1999 TC36, at wavelengths near 24 and 70 μm using the Spitzer Space Telescope. We fit these data and the visual magnitude using both the standard thermal model and thermophysical models. We find that the effective diameter of the binary is 405 km, with a range of 350-470 km, and the effective visible geometric albedo for the system is 0.079, with a range of 0.055-0.11. The binary orbit, magnitude…

The orbit, mass, size, albedo, and density of (65489) Ceto/Phorcys: A tidally-evolved binary Centaur
Abstract Hubble Space Telescope observations of Uranus- and Neptune-crossing object (65489) Ceto/Phorcys (provisionally designated 2003 FX128) reveal it to be a close binary system. The mutual orbit
The density of mid-sized Kuiper belt object 2002 UX25 and the formation of the dwarf planets
The formation of the largest objects in the Kuiper belt, with measured densities of ~1.5 g cm^(–3) and higher, from the coagulation of small bodies, with measured densities below 1 g cm^(–3), is
Physical Properties of Kuiper Belt and Centaur Objects: Constraints from the Spitzer Space Telescope
Detecting heat from minor planers in the outer solar system is challenging, yet it is the most efficient means for constraining the albedos and sizes of Kuiper belt objects (KBOs) and their progeny,
Here we report Wide-Field Planetary Camera 2 observations of the Quaoar-Weywot Kuiper Belt binary. From these observations, we find that Weywot is on an elliptical orbit with an eccentricity of 0.14
(47171) 1999 TC36, A transneptunian triple
Abstract We present new analysis of HST images of (47171) 1999 TC36 that confirm it as a triple system. Fits to the point-spread function (PSF) consistently show that the apparent primary is itself
Trans-Neptunian objects and Centaurs at thermal wavelengths
Abstract The thermal emission of Trans-Neptunian objects and Centaurs has been observed at mid- and far-infrared wavelengths—with the biggest contributions coming from the Spitzer and Herschel space
“TNOs are Cool”: A survey of the trans-Neptunian region - X. Analysis of classical Kuiper belt objects from Herschel and Spitzer observations
Context. The Kuiper belt is formed of planetesimals which failed to grow to planets and its dynamical structure has been affected by Neptune. The classical Kuiper belt contains objects both from a
New observations show that the light curve of Kuiper Belt contact binary (139775) 2001 QG298 has changed substantially since the first observations in 2003. The 2010 light curve has a peak-to-peak
Physical Properties of Transneptunian Objects
In 1992, the first body beyond Neptune since the discovery of Pluto in 1930 was found. Since then, nearly a thousand solid bodies, including some of planetary size, have been discovered in the outer
ESO large program about transneptunian objects: surface variations on (47171) 1999 TC36
Aims. We investigate the surface composition of the Plutino (47171) 1999 TC36. Methods. We completed near-infrared photometric and spectroscopic observations of (47171) 1999 TC36 with the adaptive


The high-albedo kuiper belt object (55565) 2002 AW197
We detected thermal emission from the Kuiper Belt object 2002 AW197 in 2003 December and again in 2004 April using the Multiband Imaging Photometer on the Spitzer Space Telescope. In combination with
The size and albedo of the Kuiper-belt object (20000) Varuna
Observations over the last decade have revealed the existence of a large number of bodies orbiting the Sun beyond Neptune. Known as the Kuiper-belt objects (KBOs), they are believed to be formed in
Direct Measurement of the Size of the Large Kuiper Belt Object (50000) Quaoar
We imaged the recently discovered bright Kuiper belt object (50000) Quaoar with the Hubble Space Telescope High Resolution Camera to directly determine its size. The point-spread function (PSF) of

Discovery of a Planetary-sized Object in the Scattered Kuiper Belt
We present the discovery and initial physical and dynamical characterization of the object 2003 UB313. The object is sufficiently bright that for all reasonable values of the albedo it is certain to

The color temperature of (2060) Chiron: A warm and small nucleus
We present three sets of thermal-infrared observations of (2060) Chiron, obtained in 1991, 1993, and 1994. These observations allow the first estimates of the color temperature of Chiron as well as
The binary Kuiper-belt object 1998 WW31
It is reported that the Kuiper-belt object 1998 WW31 is binary with a highly eccentric orbit (eccentricity e ≈ 0.8) and a long period (about 570 days), very different from the Pluto/Charon system, which was hitherto the only previously known binary in theKuiper belt.
Thermal Properties of Centaurs Asbolus and Chiron
