We describe the discovery of a satellite in orbit about the dwarf planet (136472) Makemake. This satellite, provisionally designated S/2015 (136472) 1, was detected in imaging data collected with the Hubble Space Telescope's Wide Field Camera 3 on UTC 2015 April 27 at 7.80 ± 0.04 mag fainter than Makemake and at a separation of 057. It likely evaded detection in previous satellite searches due to a nearly edge-on orbital configuration, placing it deep within the glare of Makemake during a…

Discovery of a Satellite of the Large Trans-Neptunian Object (225088) 2007 OR10
2007 OR10 is currently the third largest known dwarf planet in the trans-Neptunian region, with an effective radiometric diameter of ~1535 km. It has a slow rotation period of ~45 hr that was
Long-term photometric monitoring of the dwarf planet (136472) Makemake
Aims. We studied the rotational properties of the dwarf planet Makemake. Methods. The photometric observations were carried out at different telescopes between 2006 and 2017. Most of the measurements
The Short Rotation Period of Hi'iaka, Haumea's Largest Satellite
Hi'iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysis, we have
Early formation of moons around large trans-Neptunian objects via giant impacts
Recent studies1,2 have revealed that all large (over 1,000 km in diameter) trans-Neptunian objects (TNOs) form satellite systems. Although the largest Plutonian satellite, Charon, is thought to be an
Interpreting the densities of the Kuiper belt's dwarf planets
Kuiper Belt objects with absolute magnitude less than 3 (radius $\gtrsim$500 km), the dwarf planets, have a range of different ice/rock ratios, and are more rock-rich than their smaller counterparts.
Stellar Occultations by Transneptunian objects: from Predictions to Observations and Prospects for the Future
In terms of scientific output, the best way to study solar system bodies is sending spacecraft to make in-situ measurements or to observe at close distance. Probably, the second best means to learn

The case for implementation of moving target tracking is presented, a feature that will benefit from the heritage of JWST and enable a broader range of solar system observations.
The dwarf planet Makemake as seen by X-Shooter
Makemake is one of the brightest known trans-Neptunian objects, as such, it has been widely observed. Nevertheless, its visible to near-infrared spectrum has not been completely observed in medium


On the Size, Shape, and Density of Dwarf Planet Makemake
A recent stellar occultation by the dwarf planet Makemake provided an excellent opportunity to measure the size and shape of one of the largest objects in the Kuiper belt. The analysis of these
The Rotation Period and Light-Curve Amplitude of Kuiper Belt Dwarf Planet 136472 Makemake (2005 FY9)
Kuiper Belt dwarf planet 136472 Makemake, formerly known as 2005 FY9, is currently the third-largest known object in the Kuiper Belt, after the dwarf planets Pluto and Eris. It is currently second
Albedo and atmospheric constraints of dwarf planet Makemake from a stellar occultation
The disappearances and reappearances of the star were abrupt, showing that Makemake has no global Pluto-like atmosphere at an upper limit of 4–12 nanobar (1σ) for the surface pressure, although a localized atmosphere is possible.
Interpreting the densities of the Kuiper belt's dwarf planets
Kuiper Belt objects with absolute magnitude less than 3 (radius $\gtrsim$500 km), the dwarf planets, have a range of different ice/rock ratios, and are more rock-rich than their smaller counterparts.
The small satellites of Pluto as observed by New Horizons
The New Horizons results on Pluto’s small moons help to elucidate the conditions under which the Pluto system formed and evolved, and massively increase the understanding of the bodies in the outer solar system.
We report the orbital distribution of the trans-Neptunian objects (TNOs) discovered during the Canada–France Ecliptic Plane Survey (CFEPS), whose discovery phase ran from early 2003 until early 2007.
Characterization of Seven Ultra-wide Trans-Neptunian Binaries
The low-inclination component of the Classical Kuiper Belt is host to a population of extremely widely separated binaries. These systems are similar to other trans-Neptunian binaries (TNBs) in that
The solar system beyond Neptune
A new frontier in our solar system opened with the discovery of the Kuiper Belt and the extensive population of icy bodies orbiting beyond Neptune. Today the study of all of these bodies,
