Just over 24 hours before its closest approach to Ultima Thule, New Horizons has sent back the first images that begin to reveal Ultima Thule’s shape. Image-sharpening techniques combining multiple images show that Ultima Thule is elongated, perhaps twice as long as it is wide. The spacecraft was approximately 1.2 million miles (1.9 million km) from Ultima Thule when this image was taken on December 30, 2018.

This composite image of Ultima Thule was taken just 33 hours before the December 2 course-correction maneuver that fine-tuned New Horizons’ trajectory for its New Year’s flyby. At left is the full LORRI image with a yellow circle centered on the location of Ultima Thule. Unlike the LORRI images taken in August through October 2018, the object is now evident among the many background stars even without further processing. Nevertheless, Ultima Thule really stands out after subtracting the background stars; the region within the yellow box has been expanded in the star-subtracted version of the image on the right.
