There's a relevant paragraph at Wikipedia (Asteroid#Terminology) - "The main difference between an asteroid and a comet is that a comet shows a coma due to sublimation of near surface ices by solar radiation..." etc. | |

As far as the "asteroid or comet" part of the question, does the paper choose to use "asteroid" simply to avoid repeating "asteroid or comet" at every instance, or is it being actively asserted that the object is both not a comet and is an asteroid? | |
