NEA 1998 SH2 is Really a Comet

I had a look at the paper. They failed to fully appreciate the minor planet observation community (which is typical) and ignored much of the previous research, much of which has been published in specialty amateur/professional literature rather than Nature. When you do that, you end up reinventing the wheel and then giving it a new name.

What's new here is the idea that you could use signs of outgassing, based on an analysis of the orbit, as a diagnostic for determining if the object was historically a comet. I suspect this isn't as useful as they suggest it to be, because orbital data that is consistent and accurate enough over long periods of time is not generally available--at least not quite yet.
