In a press briefing that included a number of scientists working on NASA’s New Horizons mission, the first discoveries on the Kuiper Belt object cataloged as 2014 MU69 and nicknamed Ultima Thule were presented, obtained thanks to data received during the January 1, 2019 flyby. They’re based on information that’s still incomplete, which could be contradicted by high resolution photos and other data but for the moment this object doesn’t appear to have neither moons nor rings, or at least not of relevant sizes, no impact craters were found on its surface nor were traces of atmosphere.
