Ultima Thule has a shape even stranger than expected

NASA and the Johns Hopkins University Applied Physics Laboratory have published new images of the Kuiper belt Object cataloged as 2014 MU69 and nicknamed Ultima Thule along with animations that show new details of its shape. A sequence of 14 images captured by the New Horizons space probe during its January 1, 2019 flyby shows that the this object’s two lobes are not vaguely spherical as it seemed but in particular the larger one is definitely flat, to the point that it was compared to a pancake, and it’s not clear why it has that shape.
