Ultima Thule as a single body
Ultima Thule as a single body
Artist’s impression of the trans-Neptunian object (486958) 2014 MU69, or Ultima Thule, as a 30-kilometre coherent body. Based on the light curves obtained from ground-based telescopes and the SOFIA airborne observatory, it is not entirely clear whether the target object of NASA’s New Horizons spacecraft for 1 January 2019 has one or possibly two bodies, which are either totally separate or weakly joined.
