Here it is:
At left is a composite of two images taken by New Horizons' high-resolution Long-Range Reconnaissance Imager (LORRI), which provides the best indication of Ultima Thule's size and shape so far. Preliminary measurements of this Kuiper Belt object suggest it is approximately 20 miles long by 10 miles wide (32 kilometers by 16 kilometers). An artist's impression at right illustrates one possible appearance of Ultima Thule, based on the actual image at left. The direction of Ultima's spin axis is indicated by the arrows.

Resolution and the addition of colour will happen soon... This is another inbound image.

Three stacked images on the way in...
This sequence of three images, received on Dec. 31, 2018, and taken by the LORRI camera onboard New Horizons at 70 and 85 minutes apart illustrates the rotation of Ultima Thule.
