Finding the shape of 2014 MU69 from occultations
On three occasions in June and July 2017, New Horizons mission team members attempted to track a small, distant Kuiper Belt object, 2014 MU69, as it passed in front of a star – an event known as an occultation. The colored lines mark the path of the star as seen from different telescopes on each day; the blank spaces on those lines indicate the few seconds when MU69 blocked the light from the star. Scientists are using these observations to craft a picture of MU69 and any companion bodies. This diagram was drawn before the discovery of a few bugs in the astrometry software. Fixing those bugs and improvements in Hubble image reduction brought the main body of MU69 closer to its astrometry-predicted position and brought the single SOFIA "blip" closer to the main body.
