There's a diagram at NASA: http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2004%20Q2;orb=1;cov=0;log=0#orb the diagram seems to suggest it doesn't even get as close to the Sun as Earth. Can anybody shed any light on the contradiction I perceive? Am I missing some clues? This article, and others I read, say its orbit takes it close to the sun, within the orbit of Mercury.

Can anybody shed any light on the contradiction I perceive? Am I missing some clues?

I don't even know if it's possible to distinguish the two species from the observations..! Just a chemist's curiosity:

If it has a prograde orbit within a few degrees of the ecliptic plane then it is far more likely to be from the Kuyper Belt. If it is retrograde or highly inclined then the implication is that it is an Oort Cloud comet, although an extra solar origin would be a possibility.

Because Ms. Atkinson is the best and hardest working dang science news writer on the web, that's why. Check out her website. I like explanation 1: It came from another star system. Scary in that we may need to look for stray comets traveling inter-solar system for NEA objects that could end the party sooner than as planned by Sol. Why is this site so slow????

Note, however, that this isn't a matter of spelling. I don't ever comment to correct spelling - at most I may mention some spelling mistake <i>en passant</i> while I'm commenting something else, and that rarely. Heck, I'm not even a native English speaker, and I have my own spelling mistakes to bother with. No. This is a typo that could confuse some readers, which is another beast alltogether. These I do mention whenever I spot them, because I think it's in the interest of UT to correct them asap.

How about sending an email to the author. It always disappoints me when the comments section is used to correct spelling. Jorge.

Surely you meant unusual?
