When I saw the objekt in the article I came to think on Star Trek The Voyage Home.
It's very interesting to read nevertheless.
The observations also confirmed this object – now certain to be an asteroid rather than a comet, as it had no visible coma – was dark and reddish in color. This was the result of cosmic rays blasting it for the millions of years it has been traveling through space, irradiating its surface.
