ultima thule has no light curve. The most likely explanation is that an energy source is producing a dusty atmosphere. That energy source must be LENR. In a asteroid like body that is only 18 miles in diameter, it is too small for the standard heat sources that are assumed to make a celestial body geologically active. For example, Pluto which is geologically active was assumed to produce heat through the generation of ice as it solidifies over 4.6 billion years. Such a claim is not possible when it comes to such a small body as Ultima Thule happens to be. Other reasons that are given are also precluded because of a small body size We will know what is happening in a few more days.
