The centerpiece objective of the NASA New Horizons first Kuiper Extended Mission (KEM-1) was the close flyby of the Kuiper Belt Object KBO) 2014 MU69, nicknamed Ultima Thule. On 1 Jan 2019 this flyby culminated, making the first close observations of a small KBO. Initial post flyby trajectory reconstruction indicated the spacecraft approached to within ~3500 km of MU69 at 5:33:19 UT. Here we summarize the earliest results obtained from that successful flyby. At the time of this submission, only…

The HST lightcurve of (486958) 2014 MU69
Abstract We report Hubble Space Telescope (HST) lightcurve observations of the New Horizons spacecraft encounter Kuiper Belt object (KBO) (486958) 2014 MU69 acquired near opposition in July 2017. In
The natural history of 'Oumuamua
TLDR
How the observed characteristics of `Oumuamua are explained by the extensive knowledge of natural minor bodies in the authors' Solar System and the current knowledge of the evolution of planetary systems is discussed.
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 natural history of ‘Oumuamua
4 The discovery of the first interstellar object (ISO) passing through the Solar System, 1I/2017 U1 5 (‘Oumuamua), provoked intense and continuing interest from the scientific community and the
The Changing Rotational Light-curve Amplitude of Varuna and Evidence for a Close-in Satellite
From CCD observations carried out with different telescopes, we present short-term photometric measurements of the large trans-Neptunian object Varuna in 10 epochs, spanning around 19 years. We
The small inner satellites of Saturn: Shapes, structures and some implications
Abstract Properties of the small inner satellites of Saturn are updated using final Cassini image data. The equatorial ridges on Pan and Atlas are morphologically, structurally, and gravitationally
Ultima Thule (486958; 2014 MU69): Necklace, Composition, Rotation, Formation
Flyby images of Ultima Thule (486958; 2014 MU69) show a comparatively bright ``necklace'' between its two lobes, in contrast to its generally low albedo. The necklace is found in the most shaded, and
Emissivity of Ammonia Ice
Bodies in the outer Solar System may consist of, or be covered by, solid ammonia. Their temperature depends on its emissivity. We calculate that emissivity as a function of frequency, angle and

Fly-by images of (486958) Arrokoth (Ultima Thule, 2014 MU69) show a comparatively bright ‘necklace’ in the neck, or cleft, between its two lobes, in contrast to its generally low albedo. We suggest
